List<V>	readAll()	Returns all queue elements at once
RFuture<Void>	transferAsync(V e)	Transfers the element to waiting consumer which invoked RBlockingQueueAsync.takeAsync() or RBlockingQueueAsync.pollAsync(long, java.util.concurrent.TimeUnit) method at the moment of transfer.
RFuture<Boolean>	tryTransferAsync(V e)	Tries to transfer the element to waiting consumer which invoked RBlockingQueueAsync.takeAsync() or RBlockingQueueAsync.pollAsync(long, java.util.concurrent.TimeUnit) method at the moment of transfer.
RFuture<Boolean>	tryTransferAsync(V e, long timeout, TimeUnit unit)	Transfers the element to waiting consumer which invoked RBlockingQueueAsync.takeAsync() or RBlockingQueueAsync.pollAsync(long, java.util.concurrent.TimeUnit) method at the moment of transfer.

Method Details

tryTransferAsync

RFuture<Boolean> tryTransferAsync(V e)

Tries to transfer the element to waiting consumer which invoked RBlockingQueueAsync.takeAsync() or RBlockingQueueAsync.pollAsync(long, java.util.concurrent.TimeUnit) method at the moment of transfer.

Parameters:

e - element to transfer

Returns:

true if element was transferred, otherwise false

transferAsync

RFuture<Void> transferAsync(V e)

Transfers the element to waiting consumer which invoked RBlockingQueueAsync.takeAsync() or RBlockingQueueAsync.pollAsync(long, java.util.concurrent.TimeUnit) method at the moment of transfer. Waits if necessary for a consumer.

Parameters:

e - the element to transfer

Throws:

ClassCastException - if the class of the specified element prevents it from being added to this queue

NullPointerException - if the specified element is null

IllegalArgumentException - if some property of the specified element prevents it from being added to this queue

tryTransferAsync

RFuture<Boolean> tryTransferAsync(V e,
 long timeout,
 TimeUnit unit)

Transfers the element to waiting consumer which invoked RBlockingQueueAsync.takeAsync() or RBlockingQueueAsync.pollAsync(long, java.util.concurrent.TimeUnit) method at the moment of transfer. Waits up to defined timeout if necessary for a consumer.

Parameters:

e - the element to transfer

timeout - the maximum time to wait

unit - the time unit

Returns:

true if the element was transferred and false otherwise

readAll

List<V> readAll()

Returns all queue elements at once

Returns:

elements
