## umontreal.iro.lecuyer.contactcenters.ctmc
Class CallCenterCTMCQueues

    java.lang.Object
      umontreal.iro.lecuyer.contactcenters.ctmc.CallCenterCTMCQueues

All Implemented Interfaces:
  Cloneable

    public class CallCenterCTMCQueues

extends Object
implements Cloneable

Provides helper method used to maintain information on queued calls, for a CTMC model of a call center. This class encapsulates an array of circular arrays of integers representing the waiting queues, and provides the `init()` that should be called after `CallCenterCTMC.initEmpty()` or `CallCenterCTMC.init(CallCenterCTMC)`. It also implements the `update(CallCenterCTMC,TransitionType)` method which should be called after each transition to update the waiting queues. The methods `getLastWaitingTime(int)`, and `getQueue(int)` can then be used by CTMC models to implement the interface `CallCenterCTMCWithQueues`.

Constructor Summary
`CallCenterCTMCQueues(CallCenterCTMC ctmc)` Constructs a new object holding queueing information from the call center CTMC model `ctmc`.

Method Summary
`CallCenterCTMCQueues` | `clone()` Constructs and returns a deep copy of this object, including copies of the waiting queues.
`int` | `getLastWaitingTime(int k)` Returns the number of transitions spent by the last call of type `k` having left the queue, provided that the `update(CallCenterCTMC,TransitionType)` method has been called after each transition.
`CircularIntArray` | `getQueue(int k)` Returns the circular array of integers containing the transition number at which each call of type `k` entered the queue, provided that the `update(CallCenterCTMC,TransitionType)` method has been called at each transition.
`void` | `init()` Empties all the circular arrays representing waiting queues, and resets the last waiting times to 0.
`void` | `init(CallCenterCTMCQueues q)` Initializes this object with the contents of the other object `q`.
`void` | `update(CallCenterCTMC ctmc, TransitionType type)` Updates the status of the waiting queues after a transition of type `type` of the CTMC model `ctmc`.

Constructor Detail

### CallCenterCTMCQueues

    public CallCenterCTMCQueues(CallCenterCTMC ctmc)

  Constructs a new object holding queueing information from the call center CTMC model `ctmc`.

  Parameters:
    `ctmc` - the call center CTMC model.

Method Detail

### getQueue

    public CircularIntArray getQueue(int k)

  Returns the circular array of integers containing the transition number at which each call of type `k` entered the queue, provided that the `update(CallCenterCTMC,TransitionType)` method has been called at each transition.

  Parameters:
    `k` - the tested call type.
  Returns:
    the circular array representing the queue.

### getLastWaitingTime

    public int getLastWaitingTime(int k)

  Returns the number of transitions spent by the last call of type `k` having left the queue, provided that the `update(CallCenterCTMC,TransitionType)` method has been called after each transition.

  Parameters:
    `k` - the tested call type.
  Returns:
    the number of transitions spent in queue.

### init

    public void init()

  Empties all the circular arrays representing waiting queues, and resets the last waiting times to 0.

### init

    public void init(CallCenterCTMCQueues q)

  Initializes this object with the contents of the other object `q`.

  Parameters:
    `q` - another object holding queue information.

### update

    public void update(CallCenterCTMC ctmc,
                       TransitionType type)

  Updates the status of the waiting queues after a transition of type `type` of the CTMC model `ctmc`.

  Parameters:
    `ctmc` - the CTMC model in which the transition occurred.
    `type` - the type of transition.

### clone

    public CallCenterCTMCQueues clone()

  Constructs and returns a deep copy of this object, including copies of the waiting queues.

  Overrides:
    `clone` in class `Object`
