Method Summary

Modifier and Type	Method and Description
default boolean	hasServerAccessCredits(Q queue, SimQueueState<SimJob,Q> queueState) Checks whether a given state represents a queue-state with server-access credits available.
default boolean	isQueueAccessVacation(Q queue, SimQueueState<SimJob,Q> queueState) Checks whether a given state represents a queue-state vacation on given queue.
boolean	isStartArmed(Q queue, SimQueueState<SimJob,Q> queueState) Checks whether a given state represents StartArmed on given queue.

Method Detail

isQueueAccessVacation

default boolean isQueueAccessVacation(Q queue,
                                      SimQueueState<SimJob,Q> queueState)

Checks whether a given state represents a queue-state vacation on given queue.

The default implementation returns queueState.isQueueAccessVacation ().

Parameters:

queue - The queue.

queueState - The queue state, non-null.

Returns:

True if the state represents a queue-access vacation at given queue.

Throws:

IllegalArgumentException - If any of the arguments is null.

hasServerAccessCredits

default boolean hasServerAccessCredits(Q queue,
                                       SimQueueState<SimJob,Q> queueState)

Checks whether a given state represents a queue-state with server-access credits available.

The default implementation returns queueState.getServerAccessCredits () > 0.

Parameters:

queue - The queue.

queueState - The queue state, non-null.

Returns:

True if the state represents a queue-state with server-access credits available.

Throws:

IllegalArgumentException - If any of the arguments is null.

isStartArmed

boolean isStartArmed(Q queue,
                     SimQueueState<SimJob,Q> queueState)

Checks whether a given state represents StartArmed on given queue.

Parameters:

queue - The queue.

queueState - The queue state, non-null.

Returns:

True if the state represents StartArmed at given queue.

Throws:

IllegalArgumentException - If any of the arguments is null.
