Global Install Handlers

###### Identifier:

org.eclipse.update.core.installHandlers

###### Description:

Extension point for registering global install handlers. Global install handlers can be referenced by features (using the `<feature> <install-handler>` tags) without having to include a copy of the handler code as part of the downloadable feature.

###### Configuration Markup:

###### Examples:

The following is an example of new global install handler registration:

       <extension
            id="custom"
            point="org.eclipse.update.core.installHandlers"
            name="Custom install handler">
         <install-handler
            class="com.xyz.update.CustomInstallHandler">
         </install-handler>
       </extension>

###### API Information:

Registered install handler classes must implement `org.eclipse.update.core.IInstallHandler` interface. Implementers should extend base class `org.eclipse.update.core.BaseInstallHandler`.

###### Supplied Implementation:

The platform supplies a simple install handler that is registered as `org.eclipse.update.core.DefaultInstallHandler`. If used, it will copy any non-plug-in data entries provided with the feature into the feature installation directory.
