Interfaces

The syntax for defining an interface is very similar to the syntax for defining a class or a struct: [attributes ] [access-modifier ] interface interface-name [: base-list ] {interface-body } Access modifiers (public, private, etc.) work just as they do with classes. It is common (but not required) to begin the name of your interface with a capital I The body of the interface is defined within braces, just as the body of a class would be. Suppose you want to create an interface to define the contract for data being stored to a database or file. Your interface will define the methods and properties a class will need to implement in order to be stored to a database or file. You decide to call this interface IStorable. In this interface, you might specify two methods, Read() a

Use SAP applications enable customers to enhance application source code without making modifications and thus meet customer-specific requirements that are not provided for in the standard shipment. The applications can use Business Add-Ins (BAdIs) for this purpose. Furthermore, if customers use applications that exchange messages by using XI, they can define data type enhancements for Integration Repository data types. Customers can use these enhancements to send additional data with a message and can access this data by using BAdIs, for example. Prerequisites Customers or partners have to create data type enhancements in a separate software component version and a separate namespace. This software component version must be based on the SAP software component version in which the dat

Use Proxy objects implement message interfaces from the Integration Repository. That is, you use proxies to implement the actual message exchange that is described in the Integration Builder. Integration You create proxy object in the development system by using proxy generation. Features You can use message interfaces to create the following proxy objects: · ABAP proxy objects or · Java proxy objectsABAP Proxy GenerationProxy Generation Developing Message InterfacesExporting XSD and WSDL Documents Developing Messag...Java Proxy Objects Enumerations Developing Message...Java Proxy Objects Tables Developing Message Inter...Java Proxy Objects Developing Message InterfacesABAP Proxy Objects Developing Message InterfacesProxy Objects Developing Message InterfacesData Typ

Definition All ABAP objects that are created when you generate an interface object from the Integration Repository in an SAP system are called ABAP Proxy Objects. Structure You can divide the different interface objects (the objects from the Integration Repository from which you generate proxies) into two classes: The message interface itself and the corresponding parameters and data types (also see: Converting WSDL to the Target Language). Each generated proxy object can be assigned to its corresponding interface object in the Integration Repository even after generation. The ABAP proxy generation function notes this assignment using metadata, which is transported with the proxy object. Interfaces Message interfaces can have the mode synchronous or asynchronous (see: Communication Pa

Definition All Java objects that are created from a message interface from the Integration Repository in an SAP system, are called Java Proxy Objects. Multiple proxy objects are created in the system for each message interface (Java classes or Java interfaces). Message interfaces contain message types, and these in turn contain data types.All objects referenced to message interfaces (including fault message types), are also called Interface Objects. They are the counterparts of the generated proxy objects. Structure You can divide the different interface objects into two classes: The message interface itself and the corresponding parameters and data types (also see: Converting WSDL to the Target Language). Each generated proxy object can be assigned to its corresponding interfa

Unbounded Occurring Elements in XSD Neither XSD nor Java has an explicit table type. However, in XSD you can define elements so that there is no limit to how often they may occur (also see: Elements and Attributes). For example, assume you require a data type staff, which you can use to select a group of colleagues as members of staff and assign them a manager. The following table reflects the definition of this data type in the XSD editor: Definition of an Unbounded XSD Element Within a Structure Structure Category Type Occurrence Description staff Complex Type [-] manager Element 1 staff manager name Element xsd:string 1 birthday Element xsd:date 1 [-] employee Element 1..unbounded staff members name Element xsd:string 1 birthday Element

An enumeration is a facet that you can use to restrict the value range of a simple data type, attribute, or element. Java proxy generation generates a Java class for accessing the values. This class provides a type and value secure mapping of the enumeration by generating constants for each value and only enabling access using methods: There are two constants for each value that, where possible, have the same name as the value itself (for example, in the case of string values). Otherwise, the constants have the names value1, value2,...., valueN (with or without an underscore): A value constant of the type of the simple data type, attribute, or element. The constant therefore has the value of a possible value in the enumeration. In addition, the constant name has an underscore as a pre

Use The Integration Builder editors access repository objects directly. For example, you can load message types in the mapping editor to define a message mapping. You can also use tools from a third-party to design a mapping and then import the XSLT or Java mapping into the repository. The Integration Builder supports the export of interface objects for such scenarios. Interface Object Export Format Message Interface WSDL (Web Service Description Language) Data type, (fault) message type XSD (XML Schema Definition) Note the following here: · When exporting WSDL, the XSD of the referenced message type is contained in the exported file. · When exporting (fault) message types or data types, the Integration Builder checks whether there are any references to

Purpose Proxy generation converts non-language-specific interface descriptions in WSDL into executable interfaces known as Proxies. Depending on the target programming language, you choose one of the following: · ABAP proxy generation is part of the SAP Web AS 6.40. ABAP proxy generation enables you to generate proxies to communicate by using the Web service infrastructure and by using SAP Exchange Infrastructure. ABAP proxies that were generated from message interfaces in the Integration Repository (IR) can be used in both infrastructures. This means that if none of the Integration Server services are required for a proxy-to-proxy communication scenario in ABAP, you can use a point-to-point connection using the Web service infrastructure instead. · Java proxy generation

Use If you have already defined a data type as an XML Schema Definition (XSD) outside the Integration Builder, you can import this definition for a data type in the XSD editor. You use this as a template and can change it as required using the XSD editor. If more than one data type is defined in an XSD definition, the XSD editor can only import one of the globally defined data types. If the XSD data type to be imported contains references to other data types, the XSD editor does not import these referenced data types. After import, the references no longer link to these data types. However, you can import data types that reference each other to the Integration Repository one after the other. The Integration Builder recognizes automatically if data types for previously invalid references

Procedure ... 1. Create a data type in your namespace on the design maintenance screen of the Integration Builder (see also: Creating a New Object). 2. Choose the Definition tab page. The XSD editor automatically selects the category Simple Type when you create a data type. 3. To insert a subnode, call the context menu for the root element and choose either Insert Subelement or Insert Attribute. This is only possible if the root element has not yet been assigned a type. If a type has already been specified in the Type column, you can delete it again by selecting the type with the cursor, deleting the selected text by choosing the Del button, and then confirming the change by choosing Return. 4. The type then automatically changes to

Procedure ... 1. Create a data type in your namespace on the design maintenance screen of the Integration Builder (see also: Creating a New Object). 2. Choose the Definition tab page. The XSD editor automatically selects the category Simple Type when you create a data type. 3. In the Type column, define a built-in data type by clicking or double clicking the cell and selecting a value from the list box. You can also reference other simple data types by using the input help in the toolbar or in the list box. You cannot reference complex data types. You cannot make any entries for simple data types in the Occurrence column. 4. To define the facets of the simple data type in the Details column, call the input help by double clickin

Use Facets enable you to restrict the value range of a data type in XML schema to a particular subset. This enables you to determine exactly which value is expected in a special case for a simple data type, an element, or an attribute. For example: · A telephone number (using a pattern on a string) · A selection of permitted values, for example to classify the different classes for a flight (using an enumeration) Prerequisites Before you can use a facet, you must have selected a built-in data type in the Type column for your simple data type, element, or attribute. Otherwise the input field in the Details column remains locked. Features Using the XSD editor, you can further restrict the value range of a built-in data type for simple data types, elements or attributes

You create complex data types using elements and attributes in the XSD editor: Node Type Use Example Instance Element Create structured data types. Elements that have a type cannot contain subelements. Value of f1 Value of f2 Attribute Add attributes to elements. Attributes cannot usually have subnodes. myAttr="AttributeValue"> Element Value You can flag an attribute as optional or required in the Occurrence column. These values mean the same for elements with an occurrence of 0..1 or 1. The only difference between elements and attributes is that attributes cannot have subnodes and that the same attribute cannot be used more than once in an element. Frequently Occurring Elements XML schema does not recognize tables but permits instead th

Use The XSD editor enables you to define data types and data type enhancements without needing extensive knowledge of XML schema. You construct a data type in the XSD editor by using a table that returns the structure of the data type. As in XML schema, you can define both simple and complex data types that are automatically converted to XML Schema Definition (XSD) by the editor. The XML Schema Definition determines which tags can be transferred with which values in the payload. When defining a data type, the selection of values that you can enter in the table is context-dependent. Therefore, you cannot enter invalid entries. Prerequisites You have already created a data type. To access the XSD editor, select the Definition tab page (see: Data Types). Features The XSD editor compr

Use A data type is a basic unit for defining the structure of the data for a message type and, as a result, for the message to be exchanged. Integration A data type is an XML Schema Definition (XSD). This definition determines how the valid payload of a message will look. Data types in XML schema are only an abstract description of a structure that you can assign to elements in an XML schema definition. A message type or a fault message type that references a data type determines the name of the root element of a message. Alternatively, you can use external definitions, which already contain data types, or import an XSD definition as a template. Customers and partners can use data type enhancements to add their own fields to SAP data types in the Integration Repository. Prerequisi

Use Fault message types are designed for application-specific errors that occur on the inbound side and that are reported back to the sender or persisted in monitoring. · In the synchronous case, when an application-specific error occurs on the inbound side, instead of sending a response message back to the sender, the application can send a fault message to handle the error. · The fault message of the application for an asynchronous ABAP server proxy is persisted for monitoring. In the case asynchronous of Java server proxies, the fault message is part of a negative application acknowledgement (see Acknowledgments). Application-specific means that the application on the inbound side triggers the error itself because, for example, the request message did not contain su

Use A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type: · More than one message interface can use the same message type. For example, an asynchronous outbound message interface and an asynchronous inbound message interface can reference the same message type because the request message does not need to be mapped. · When defining a message mapping you can directly reference message types to map messages from an outbound interface to messages from a receiver interface. For technical reasons, a data type is not sufficient to describe the instance of a message. In XML schema, data types are defined as abstra

Purpose By using platform-independent message interfaces you can define the type of communication and the data to be exchanged before you actually implement your cross-system process. See also: Introduction to Interface Development. Overview The following graphic displays the class model for message interfaces in the Integration Builder: As with all repository objects, message interfaces are organized by using Repository namespaces, which are assigned to a software component version (see also: Organization of Shipment Contents). You can construct message interfaces in the following way: · Using message types and data types. This two-layer structure uses WSDL (Web Service Description Language) and is oriented towards maximum reusability. Customers can also use data type enh

Purpose Generally speaking, interfaces are where functions in a system can be executed. In the context of SAP Exchange Infrastructure, only the following interfaces are relevant: · Interfaces designed for message exchange between application systems · Interfaces used by a cross-component integration process to receive or send messages, or both Starting with a cross-system integration process, you can then derive the corresponding interfaces required. SAP Exchange Infrastructure supports this process by using an integration scenario to describe the collaborative process. The integration scenario summarizes the interfaces required for this collaborative process. You can use SAP interfaces that already exist in systems, non-SAP interfaces that are connected to SAP Excha

abstract An formally unfinished class or method, marked with the keyword abstract. It is a way of preventing someone from instantiating a class that is supposed to be extended first. An abstract class is deliberately missing some or all of the method bodies. An abstract method is deliberately missing its method body. An abstract class is similar to an interface which is missing all the method bodies. An abstract class provides a base for someone to extend an actual class. You can't use new on abstract classes, but you can use abstract references, which always point to objects of a class that extends the abstract class. Interfaces are implicitly abstract as are all their methods.To use make practical use of an abstract class, you must define a non-abstract class that extends the abstract on

The .NET Framework provides classes that enable you to handle HTTP requests for the ASP.NET Web pages and services. You can handle HTTP requests by creating a class that implements the IHttpHandler interface contained in the System.Web namespace.The System.Web namespace contains classes and interfaces that enable you to handle the communication between browsers and Web servers. Before you can use a class that implements the IHttpHandler interface, you need to write the section in the Web.config configuration file to map the class that implements IHttpHandler to a URL request.Before you create an HTTP Handler, let us look at the IHttpHandler and IHttpHandlerFactory interfaces, and some of the classes contained in the System.Web namespace.IHttpHandler interfaceThe IHttpHandler interface mus

This error kept me busy all morning and part of the afternoon: An error has occurred while establishing a connection to the server.  When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) This error seems to be affecting more developers - according to some forums and blogs - but none of them had a solution. After trying some workarounds I finally found one that worked: The SQL port - 1433 -  needs to be included as part of Data Source on the connection string:...Data Source=mysqlserverinstance1,1433;... That did it for me. Note that the error was happening when connecting to a SQL Server 2000 from a .NET 2.0 web application.

     This is an update to a previous post regarding the change of mac address in Debian. In the previous tutorial I told you can change it by ifconfig from a root account. Now I’m going to teach you how to set an interface mac address using /etc/network/interfaces . This is a better way to set your mac address because the mac you set in /etc/network/interfaces will always load when the interfaces are loaded so you don’t have to worry about the mac after reboot for example. Let’s start by looking at my /etc/network/interfaces it looks like this:   #This file describes the network interfaces available on your system # and how to activate them.

We all know how successful the Apple iPod became which was in part to its cool click wheel, not here is another MP3 player trying something different. This new MP3 player is just a concept, but if it ever reaches production it will allow the user to change the music and the volume by rolling the trackball. Now a trackball is old tech but being used on an MP3 player is a little different to what most music lover’s use. Not that this feature will be handy, but I like the idea of being able to turn this player upside down on a table and then change music just by rolling it on the table (maybe that will get boring quick). One problem with concepts is that most never make it to the real world, what do you think of this design? Source Written by Daniel for Product ReviewsIn Sections: Electronics, Portable Music Players

The .NET Framework contains both classes and interfaces. When you write routines, you will find that you probably know which .NET class you’re using. However, your code will be more robust and more reusable if you program using any supported interfaces instead of the class you happen to be working with at the time. Consider this code: private void LoadList (object [] items, ListBox l) {for (int i = 0; i l.Items.Add (items[i].ToString ());} This function loads a ListBox from an array of any kind of objects. The code is limited to an array only. Suppose that later you find that objects are stored in a database, or in some other collection. You need to modify the routine to use the different collection type. However, had you written the routine using the ICollection interface, it would work on any type that implements the ICollection interface: private void LoadList (ICollection items, ListBox l) {foreach (object o in items)l.Items.Add (o.ToString ());} The ICollection interface is

Nokia's upper management quickly reverses its thoughts on optical and touch sensitive interfaces for mobile devices Last week Nokia gave a vote of no confidence to the use of touchscreen technology in mobile phones. In an interview with Swedish newspaper, E24.SE, Nokia's General Manager of Mobile Devices, Antti Vasara, simply said that users prefer keyboards and joysticks over touchscreen displays and that Nokia is not enthusiastic about touch screens. Despite this, he did say that if Nokia sees the demand for touch screens, the company would use them in mobile devices.A week later it seems that Nokia has seen the demand for touchscreen technology in mobile phones. Tero Ojanpera, Chief Technology Officer of Nokia, yesterday said, "Optical sensors and touch will be the next big things." His statement is a 180 degree turn from what Vasara said last week.Ojanpera lauded touch screens, claiming the technology would allow cell phone makers to hide keypads. In addition, he said tha

These interfaces are implemented and used in the same manner as those you created earlier.Common interfaces of the .NET Framework Class Library. InterfaceDescriptionIComparableInterface IComparable can also be used to allow objects of a class that implements the interface to be compared to one another. The interface contains one method, CompareTo, that compares the object that calls the method to the object passed as an argument to the method. Classes must implement CompareTo to return a value indicating whether the object on which it is invoked is less than (negative integer return value), equal to (0 return value) or greater than (positive integer return value) the object passed as an argument, using any criteria specified by the programmer.

Most Hibernate-related application code primarily interacts with four interfaces provided by Hibernate Core:org.hibernate.Sessionorg.hibernate.SessionFactoryorg.hibernate.Criteriaorg.hibernate.QueryThe Session is a persistence manager that manages operation like storing and retrieving objects. Instances of Session are inexpensive to create and destroy. They are not thread safe.The application obtains Session instances from a SessionFactory. SessionFactory instances are not lightweight and typically one instance is created for the whole application. If the application accesses multiple databases, it needs one per database.The Criteria provides a provision for conditional search over the resultset.One can retrieve entities by composing Criterion objects. The Session is a factory for Criteria.Criterion instances are usually obtained via the factory methods on Restrictions.Query represents object oriented representation of a Hibernate query.

What is an interface?From my previous posts you must already know how to derive a class from another class, but the real power of inheritance lies in inheriting from an interface. An interface allows you to completely separate the name of a method from its implementation. In an interface, no method can include a body, i.e. an interface provides no implementation whatsoever. It stresses more on what is to be done than how it is to be done. An interface can be implemented by any number of classes. One class can implement any number of interfaces. Interfaces only include method signatures; their implementations are determined by their derived classes. Thus, two classes can implement the same interface in different ways. C# supports "one interface and multiple methods".An example, how to declare an interface:interface IDispay //Declasre IDisplay as an interface { // no access modifiers, methods are public // no implementation  void
