match

public abstract boolean match(SimEvent event)

The match function which must be overridden when writing a new predicate. The function is called with each event in the deferred queue as its parameter when a Simulation.select() call is made by the user.

Parameters:

event - The event to test for a match.

Returns:

The function should return true if the event matches and should be selected, or false if it does not match the predicate.
