Examples of org.mitre.sim.Trigger.condition()

org.mitre.sim.Trigger.condition()

Decision logic of the trigger. Instances of trigger are used by simulation developers to detect changes in the simulation environment and trigger action in their entities. Triggers are used to wake up entities whose {@link org.mitre.sim.Entity#agenda() agendas}are suspended in a call to {@link org.mitre.sim.Entity#waitForActionOrTrigger(Trigger[] cs,double backStop) waitForActionOrTrigger}. The simulation executive may invoke this method an undetermined number of times. Therefore evaluation of the condition method should have no side effect in the simulation. @return The value of the developer supplied condition. @see org.mitre.sim.Entity#waitForActionOrTrigger(Trigger[] cs,double backStop)
