isEmpty

public boolean isEmpty()

Determine whether or not the context is empty. Objects bound directly to the context or subcontexts are all that is considered. The environment of the context is not considered.

Returns:

true of the context is empty, else false.

Set the name of the Context. This is only used from createSubcontext. It might get replaced by adding more constructors, but there is really no reason to expose it publicly anyway.

Parameters:

name - the Name of the context.

Throws:

NamingException - if the subContext already has a name.

forceClose

public void forceClose()
                throws NamingException

Throws:

NamingException
