Method Detail

init

public void init(Population p,
                 int index)

User entities can extend this method

handleEvents

public Time handleEvents(EventList el,
                         Time t)

User entities MUST extend this method : deal with events in el up to time t, and advance the entity's time to at least t and return the time actually advanced to (which may be later than t, as long as the state can be rewound back to t and no new events are generated after t). If the event type of incoming events is not recognised, the method defaultEventHandler() should be called.

Parameters:

el - The (possible empty) event list in time stamp order

t - The time to advance to

Returns:

the time actually advanced to (must be >= t)

defaultEventHandler

reset
