Method Detail

initialize

public void initialize(PluginLinker linker)
                throws PluginInitializerException

Perform first initialization of the plugin. This is called after the plugin is instantiated, but before it is asked to provide any of its API implementations. Any APIs the plugin declared it needed for initialization will be available through the linker when this method is called.

Plugins should perform any time-consuming initialization in this method, rather than in the constructor or static initializers, and should use this method to report any fatal errors during initialization.

Specified by:

initialize in interface PluginInitializer

Overrides:

initialize in class BasicPluginInitializer

Parameters:

linker - the linker for this plugin.

Throws:

PluginInitializerException - thrown if the plugin could not initialize itself.

getAPIImplementation

public Object getAPIImplementation(Class apiClass,
                                   PluginLinker linker)
                            throws PluginInitializerException

A plugin must implement this method to provide the implementations of the APIs that it provides. This method is called after the initialize() method. Any APIs the plugin declared it needed in to implement this API will be available through the linker when this method is called.

Plugins should perform any time-consuming initialization in this method, rather than in the constructor or static initializers, and should use this method to report any fatal errors during initialization.

Specified by:

getAPIImplementation in interface PluginInitializer

Overrides:

getAPIImplementation in class BasicPluginInitializer

Parameters:

apiClass - the class of the API to implement

linker - the linker for this plugin.

Returns:

an object implementing the API.

Throws:

PluginInitializerException - thrown if the plugin could not implement the API.

shutDown

public void shutDown(PluginLinker linker)
              throws PluginInitializerException

Perform finalization and shutdown of the plugin. This is called when the plugin is being unplugged.

Specified by:

shutDown in interface PluginInitializer

Overrides:

shutDown in class BasicPluginInitializer

Parameters:

linker - the linker for this plugin.

Throws:

PluginInitializerException - thrown if the plugin could not shut down.
