Method Detail

pollFirstFromAnyAsync

RFuture<V> pollFirstFromAnyAsync(long timeout,
                                 TimeUnit unit,
                                 String... queueNames)

Retrieves and removes first available head element of any queue in async mode, 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

pollLastFromAnyAsync

RFuture<V> pollLastFromAnyAsync(long timeout,
                                TimeUnit unit,
                                String... queueNames)

Retrieves and removes first available tail element of any queue in async mode, 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

putFirstAsync

RFuture<Void> putFirstAsync(V e)

Adds value to the head of queue.

Parameters:

e - value

Returns:

void

putLastAsync

RFuture<Void> putLastAsync(V e)

Adds value to the tail of queue.

Parameters:

e - value

Returns:

void

pollLastAsync

RFuture<V> pollLastAsync(long timeout,
                         TimeUnit unit)

Retrieves and removes value at the tail of queue. If necessary waits up to defined timeout for an element become available.

Parameters:

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

unit - a TimeUnit determining how to interpret the timeout parameter

Returns:

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

takeLastAsync

RFuture<V> takeLastAsync()

Retrieves and removes value at the tail of queue. Waits for an element become available.

Returns:

the tail element of this queue

pollFirstAsync

RFuture<V> pollFirstAsync(long timeout,
                          TimeUnit unit)

Retrieves and removes value at the head of queue. If necessary waits up to defined timeout for an element become available.

Parameters:

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

unit - a TimeUnit determining how to interpret the timeout parameter

Returns:

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

takeFirstAsync

RFuture<V> takeFirstAsync()

Retrieves and removes value at the head of queue. Waits for an element become available.

Returns:

the head element of this queue
