FifoServerQueue
public FifoServerQueue(Simulation sim, String name, boolean intern, QS... servers) throws IllegalArgumentException Constructor.- Parameters:
sim
- the simulationname
- the name of the queueintern
- true if the queue name should be interned in the simulation tables; false otherwiseservers
- the queue's servers- Throws:
IllegalArgumentException
- typically means a name is already in use

Method Details
-
clone
Creates and returns a copy of this object. This method will throw the exception CloneNotSupportedException if the object is interned.- Overrides:
clone
in classObject
- Throws:
CloneNotSupportedException
- a clone could not be created- See Also:
-
isInterned
public boolean isInterned()Determine if an object is interned in a object namer's tables.- Specified by:
isInterned
in interfaceNamedObjectOps
- Returns:
- true if the object is interned; false if not
-
getObjectNamer
Get the object namer for a named object.- Returns:
- the object namer for this named object
-
getName
Get an object's name.- Specified by:
getName
in interfaceNamedObjectOps
- Returns:
- the name of the object
-
delete
public final boolean delete()Delete an object. An object can only be deleted once. If this method returns true, the object (if interned) will have been removed from the object namer tables.The implementations provided by
DefaultNamedObect
and generated because of a@NamedObject
annotation provide a protected method named onDelete. A subclass that overrides onDelete() must call the onDelete method of its superclass after it's onDelete method has been called and any cleanup actions performed. In some cases, this may happen at a later time (e.g., if a thread is used for some of the cleanup operations or if it is otherwise necessary to wait).- Specified by:
delete
in interfaceNamedObjectOps
- Returns:
- true if the deletion request was accepted; false otherwise
-
isDeleted
public final boolean isDeleted()Determine if an object has been deleted. An object is deleted if the method delete() has been called and returned true.- Specified by:
isDeleted
in interfaceNamedObjectOps
- Returns:
- true if deleted; false otherwise
-
deletePending
public final boolean deletePending()Determine if an object is being deleted. An deletion is pending if the method delete() has been called and returned true but the deletion has not been completed.- Specified by:
deletePending
in interfaceNamedObjectOps
- Returns:
- true if deletion is pending; false otherwise
-
