public abstract class ArrivalProcess<S extends SimProcess> extends SimProcess
ArrivalProcess is some kind of source for
SimProcess es. It makes them arrive from the 'outside world'
in the system of interest. So it can be viewed as the border of the system
(model). The user has to specify at which rate (frequency)
SimProcess es are arriving in the system. See the Constructor
for more details. The user has to derive from this class to make his own
ArrivalProcesses for the arriving processes he needs in his simulated system.
He has to implement the abstract method createSuccessor(),
which should create (instantiate) the newly arriving process. It is
recommended to use one ArrivalProcess for each different kind of arriving
process (with its specific arrival rate).| Constructor and Description |

ArrivalProcess(Model owner,
java.lang.String name,
NumericalDist<java.lang.Double> arrivalRate,
boolean showInTrace)
Constructor for an ArrivalProcess to make a certain kind of SimProcess
arrive automatically in the system at a given rate.

createSuccessor()
Implement this abstract method so it creates (instantiates) a new
SimProcess object which is arriving at the system
(border). |

getArrivalRate()
Returns the rate (frequency) at which the SimProcesses arrive at the
system.

throws SuspendExecution
ArrivalProcess is some kind of source for
SimProcess es. So its lifeCycle is quite simple: Make a
new SimProcess object and activate it. Then wait until the
next SimProcess object is arriving at the system. Note:
the first SimProcess object is arriving when this
ArrivalProcess is started! This method uses the
createSuccessor() method to create a new
SimProcess object. If this method returns
null the life cycle of this ArrivalProcess
will stop.lifeCycle in class SimProcessSuspendExecution
