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:

###### 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.
