There are two characteristics of the broadcaster that are worthy of note: Broadcasters check whether the event is consumed before each invocation of a listeners methods. Broadcasters also check to see if a given listener is interested in an event based on the modifier filter (if defined by the listener) before the event is passed onto the listener.<P><HR><P><!--
