Class SimEvent

java.lang.Object
  hades.simulator.SimEvent

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

SignalEvent, SimEvent1164, SimulatorInterruptEvent, WakeupEvent

public class SimEvent

extends java.lang.Object

implements java.io.Serializable

SimEvent - the basic Hades simulation event. If possible, use one of the createNewSimEvent() methods instead of calling the constructors directly, to allow for efficient SimEvent recycling.

• Object source the object which generated this event
• double time the event time (simulation time)
• Object arg an optional argument
• Simulatable target the target object
• Port targetPort the port of the target object. This will only be zero for StdLogic-type signals distributed to multiple input ports on the same target object.
