Interface IPlatformPlugin

All Superinterfaces:

IPluginLifecycleListener

public interface IPlatformPlugin
extends IPluginLifecycleListener

This interface represents the contract for the specification of a plugin. A IPluginProvider is responsible for serving these to requesting clients, such as the IPluginManager. The presence of an instance of an IPlatformPlugin does not necessarily mean that the plugin is loaded. An implementations of this interface represents merely a plugin configuration.

Map<String,String> getStaticResourceMap()

Returns a list of static resource paths for this plugin-in

getLifecycleListenerClassname

String getLifecycleListenerClassname()

Returns the fully qualified name of the lifecycle listener class defined by this plugin. The class must be a IPluginLifecycleListener.

Returns:

addLifecycleListener

void addLifecycleListener(IPluginLifecycleListener listener)

Registers a lifecycle listener with this plugin. This listener will be notified when lifecycle events occur on this plugin.

Parameters:

listener - a lifecycle listener

init

void init()
          throws PluginLifecycleException

Description copied from interface: IPluginLifecycleListener

Specified by:

init in interface IPluginLifecycleListener

Throws:

PluginLifecycleException - if an error occurred

loaded

void loaded()
            throws PluginLifecycleException

Description copied from interface: IPluginLifecycleListener

Called after the plugin has been registered with the platform, i.e. all content generators, components, etc. have been loaded.

Specified by:

loaded in interface IPluginLifecycleListener

Throws:

PluginLifecycleException - if an error occurred

unLoaded

void unLoaded()
              throws PluginLifecycleException

Description copied from interface: IPluginLifecycleListener

Called when the plugin needs to be unloaded. This method should release all resources and return things to a pre-loaded state.

Specified by:

unLoaded in interface IPluginLifecycleListener

Throws:

PluginLifecycleException - if an error occurred
