    3939==== Description ==== 
     40  Extension points / extensions are what makes application extensible. Simply speaking, application extensibility is adding on to already existing functionality. [[BR]] 
     41An '''extension point''' is an opening that may be added to by later code. [[BR]] 
     42An '''extension''' is code that adds onto an existing extension point. [[BR]]

    41 ==== Usage ==== 
     44==== Examples ==== 
     45These are the JPF classes and concepts which are similar to the Sophie implementation of extensions and extension points: 
     46 * [http://jpf.sourceforge.net/api/org/java/plugin/registry/ExtensionPoint.html Extension Point] 
     47 * [http://jpf.sourceforge.net/api/org/java/plugin/registry/Extension.html Extension] 
     48 
     49Concrete implementations and tests for the Sophie implementations are located in the [source:/trunk/sophie2-platform/modules/org.sophie2.core.modularity] module. in the test folder there is very useful example how to use the core.modularity library. 
     50 
     51Good example in our project is also the module [source:/trunk/sophie2-platform/modules/org.sophie2.base.dialogs]. There is [source:/trunk/sophie2-platform/modules/org.sophie2.base.dialogs/BaseDialogsModule.java BaseDialogsModule] which is module class for the base dialogs and represents the extension point(static inner class) for the dialogs, called DialogExtensionPoint. The [source:/trunk/sophie2-platform/modules/org.sophie2.base.dialogs/Dialog.java Dialog] represents the abstract class to be extended by the dialog extensions.

     53==== Diagram ==== 
     54 * The extensions and extension points defined in the project now are:

     57 
     58 * Something like a legend for the upper diagram for clear understanding about the arrows and components is created:

     63Because of the need of external resources for our jars, we decided to make an API for resource managing. It will be implemented soon. [[BR]] 
     64The resources, which need to be shared with other modules, are located in src/main/resources/distrib folder in the module which provides them.
