================================================================= Logtalk - Object oriented extension to Prolog Release 2.29.4 Copyright (c) 1998-2007 Paulo Moura. All Rights Reserved. ================================================================= To load all entities in this library load the events_loader.lgt utility file: | ?- logtalk_load(events_loader). The objects event_registry, before_event_registry, and after_event_registry implement convenient predicates for registering before and after events. The protocol event_handlersp declares the two basic event handler predicates (before/3 and after/3). You will need to refer this protocol in your objects if you want to use the super control structure (^^/1) with these predicates. The monitor object implements more sophisticated event handling predicates. Some of the objects assume that the chosen Prolog compiler defines the usual sort/2 built-in predicate.
