Method Detail

pollFromAny

V pollFromAny(long timeout,
              TimeUnit unit,
              String... queueNames)
       throws InterruptedException

Retrieves and removes first available head element of any queue, waiting up to the specified wait time if necessary for an element to become available in any of defined queues including queue own.

Parameters:

queueNames - - names of queue

timeout - how long to wait before giving up, in units of unit

unit - a TimeUnit determining how to interpret the timeout parameter

Returns:

the head of this queue, or null if the specified waiting time elapses before an element is available

Throws:

InterruptedException - if interrupted while waiting

pollLastAndOfferFirstTo

V pollLastAndOfferFirstTo(String queueName,
                          long timeout,
                          TimeUnit unit)
                   throws InterruptedException

Throws:

InterruptedException

takeLastAndOfferFirstTo

V takeLastAndOfferFirstTo(String queueName)
                   throws InterruptedException

Throws:

InterruptedException
