Method Detail

isDestroyed

public final boolean isDestroyed()

isDestroyed in interface DestructableComponent

Returns:

true iff the component has been destroyed

isInitialized

public boolean isInitialized()

Gets whether this component is initialized.

Specified by:

isInitialized in interface InitializableComponent

Returns:

true iff this component is initialized

destroy

public final void destroy()

Destroys the component.

Specified by:

destroy in interface DestructableComponent

initialize

public final void initialize()
                      throws ComponentInitializationException

Initializes the component.

Specified by:

initialize in interface InitializableComponent

Throws:

ComponentInitializationException - thrown if there is a problem initializing the component

doDestroy

protected void doDestroy()

Performs component specific destruction logic. This method is executed within the lock on the object being destroyed. The default implementation of this method is a no-op.

doInitialize

protected void doInitialize()
                     throws ComponentInitializationException

Performs the initialization of the component. This method is executed within the lock on the object being initialized. The default implementation of this method is a no-op.
