                        throws SAXException

Joins all the child receivers.

This method is called by a child receiver when it sees something that it cannot handle, or by this object itself when it sees an event that it can't process.

This method forces children to move to its final state, then revert to the parent.

Parameters:

source - If this method is called by one of the child receivers, the receiver object. If this method is called by itself, null.

Throws:

SAXException
