io.reactivex.Maybe<V>	pollLastFromAny(long timeout, TimeUnit unit, String... queueNames) Retrieves and removes first available tail element of any queue in reactive mode, waiting up to the specified wait time if necessary for an element to become available in any of defined queues including queue own.
io.reactivex.Completable	putFirst(V e) Adds value to the head of queue.
io.reactivex.Completable	putLast(V e) Adds value to the tail of queue.
io.reactivex.Single<V>	takeFirst() Retrieves and removes value at the head of queue.
io.reactivex.Flowable<V>	takeFirstElements() Retrieves and removes continues stream of elements from the head of this queue.
io.reactivex.Single<V>	takeLast() Retrieves and removes value at the tail of queue.
io.reactivex.Flowable<V>	takeLastElements() Retrieves and removes continues stream of elements from the tail of this queue.

Method Detail

pollFirstFromAny

io.reactivex.Maybe<V> pollFirstFromAny(long timeout,
                                       TimeUnit unit,
                                       String... queueNames)

Retrieves and removes first available head element of any queue in reactive 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

pollLastFromAny

io.reactivex.Maybe<V> pollLastFromAny(long timeout,
                                      TimeUnit unit,
                                      String... queueNames)

Retrieves and removes first available tail element of any queue in reactive 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

putFirst

io.reactivex.Completable putFirst(V e)

Adds value to the head of queue.

Parameters:

e - value

Returns:

void

putLast

io.reactivex.Completable putLast(V e)

Adds value to the tail of queue.

Parameters:

e - value

Returns:

void

pollLast

io.reactivex.Maybe<V> pollLast(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

takeLast

io.reactivex.Single<V> takeLast()

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

Returns:

the tail element of this queue

pollFirst

io.reactivex.Maybe<V> pollFirst(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

takeFirst

io.reactivex.Single<V> takeFirst()

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

Returns:

the head element of this queue

takeFirstElements

io.reactivex.Flowable<V> takeFirstElements()
