This new version allocates only a single event +// finder for each port for each type of event, e.g., pos(), neg(), and +// value_change(). The event finder persists as long as the port does, +// which is what the LRM dictates. Because only a single instance is +// allocated for each event type per port there is not a potential +// explosion of storage as was true in the 2.0.1/2.1 versions. +// +// Revision 1.6 2006/02/02 21:26:34 acg +// Andy Goodrich: pulled out the check I just stuck into the +// sc_event_finder::free_instances() method. It turns out the LRM says that +// sc_event_finder instances are valid as long as the sc_module hierarchy is +// valid, so we can't give the user a call to free the instances. +// +// Revision 1.5 2006/02/02 21:10:52 acg +// Andy Goodrich: added check for end of elaboration to the static method +// sc_event_finder::free_instances(). This will allow the method to be +// made public if that is desired. +// +// Revision 1.4 2006/02/02 20:43:09 acg +// Andy Goodrich: Added an existence linked list to sc_event_finder so that +// the dynamically allocated instances can be freed after port binding +// completes. This replaces the individual deletions in ~sc_bind_ef, as these +// caused an exception if an sc_event_finder instance was used more than +// once, due to a double freeing of the instance. +// +// Revision 1.3 2006/01/13 18:47:41 acg +// Added $Log command so that CVS comments are reproduced in the source. +// + +// Taf! |
