# Site Type Factory

###### Identifier:

org.eclipse.update.core.siteTypes

###### Description:

The platform update mechanism supports pluggable site type implementations. A new site type can be registered in order to support alternate site layout schemes.

The `siteTypes` extension point allows alternate site 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 site implementation.

              class="com.xyz.update.CustomSiteFactory">
          </site-factory>
       </extension>

###### API Information:

Registered factory classes must implement `org.eclipse.update.core.ISiteFactory`

###### Supplied Implementation:
