Feature Type Factory

Identifier: org.eclipse.update.core.featureTypes

Description: The platform update mechanism supports pluggable feature type implementations. A new feature type can be registered in order to support alternate packaging and verification schemes.

The featureTypes extension point allows alternate feature implementations to be registered using a symbolic type identifier. Whenever the type is referenced using this identifier, the supplied factory is used to create the correct concrete feature implementation.

Configuration Markup:

   <!ELEMENT extension (feature-factory+)>

   <!ATTLIST extension
     point CDATA #REQUIRED
     id    CDATA #IMPLIED
     name  CDATA #IMPLIED
   >

   <!ELEMENT feature-factory EMPTY>

   <!ATTLIST feature-factory
     class CDATA #REQUIRED
   >

Examples: The following is an example of new feature type registration:

   <extension
      id="custom"
      point="org.eclipse.update.core.featureTypes"
      name="Custom packaged feature">
      <feature-factory
          class="com.xyz.update.CustomFeatureFactory">
      </feature-factory>
   </extension>

API Information: Registered factory classes must implement org.eclipse.update.core.IFeatureFactory

Supplied Implementation: The platform supplies two standard implementations of feature types. One representing the default packaged feature type, and the other representing an installed feature type.
