public class Server extends DETransformer
The service time used for a job is the most recently arrived service time prior to or simultaneous with the arrival of the job (not with the time at which service begins). Thus, if you want each job to have independent service times, you should provide a new serviceTime input synchronized with each new job arrival.

Server(CompositeEntity container,
java.lang.String name)
Construct an actor with the specified container and name.
|
| Modifier and Type | Method and Description |
|---|---|
void |
attributeChanged(Attribute attribute)
If the attribute is serviceTime, then ensure that the value
is non-negative, and if the attribute is
capacity, then change the capacity of the queue.
|
java.lang.Object |
clone(Workspace workspace)
Clone the actor into the specified workspace.
|
void |
declareDelayDependency()
Declare that the output
does not depend on the input and serviceTime in a firing.
|
void |
fire()
If there is input, read it and put it in the queue.
|
void |
initialize()
Reset the states of the server to indicate that the server is ready
to serve.
|
boolean |
postfire()
If the server is free and there is at least one token in the queue,
request a firing at the current time plus the service time.
