question: public void componentAdded ( ContainerEvent e ) { Layer childLayer = ( Layer ) e . getChild ( ) ; addProjectionListener ( childLayer ) ; if ( ! removedLayers . removeElement ( childLayer ) ) { addedLayers . addElement ( childLayer ) ; } changeLayers ( e ) ; }
target:  ContainerListener Interface method. Should not be called directly. Part of the ContainerListener interface, and it's here to make the MapBean a good Container citizen.
