Adapters

Identifier:
org.eclipse.core.runtime.adapters

Since:
3.0

Description:
The adapters extension point allows plug-ins to declaratively register adapter factories. This information is used to by the runtime XML expression language to determine existence of adapters without causing plug-ins to be loaded. Registration of adapter factories via extension point eliminates the need to manually register adapter factories when a plug-in starts up.

Configuration Markup:

<!ELEMENT extension ( factory+)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED

>


<!ELEMENT factory ( adapter+)>

<!ATTLIST factory

adaptableType CDATA #REQUIRED

class         CDATA #REQUIRED

>

  • adaptableType - The fully qualified name of a class (typically implementing IAdaptable) that this factory provides adapters for.
  • class - The fully qualified name of the adapter factory class. Must implement org.eclipse.core.runtime.IAdapterFactory.

<!ELEMENT adapter EMPTY>

<!ATTLIST adapter

type CDATA #REQUIRED

>

  • type - The fully qualified name of a Java class or interface that this factory can adapt to.

Examples:
Following is an example of an adapter declaration. This example declares that this plug-in will provide an adapter factory that will adapt objects of type IFile to objects of type MyFile.


      <extension point=
"org.eclipse.core.runtime.adapters"
>
         <factory 
            class=
"com.xyz.MyFileAdapterFactory"
 
            adaptableType=
"org.eclipse.core.resources.IFile"
>
            <adapter type=
"com.xyz.MyFile"
/>
         </factory>
      </extension>
   

Supplied Implementation:
Several plug-ins in the platform provide adapters for a number of different IAdaptable objects.
