isRunning

public boolean isRunning()

Description copied from interface: Container

Returns true if the container has been started, and false if it has not been started.

Specified by:

isRunning in interface Container

start

public void start()

Description copied from interface: Container

Begin the lifecycle of the container, after which components should be accessible. Implementors should stop any component registration as of the start() call. Subsequent start() calls should be ignored.

Specified by:

start in interface Container

getParent

protected Container getParent()

getStoredComponent

protected java.lang.Object getStoredComponent(java.lang.Object key)

store

protected void store(java.lang.Object key,
                     java.lang.Object component)
