                         ToIntFunction<E> getNumBytes)

方法详细资料

getNumBytes

public int getNumBytes()

覆盖:

getNumBytes 在类中 DataQueue<E>

getNumElements

public int getNumElements()

覆盖:

getNumElements 在类中 DataQueue<E>

clear

public void clear()

覆盖:

clear 在类中 DataQueue<E>

offer

public boolean offer(E element)

从类复制的说明: DataQueue

Adds an element to this queue.

覆盖:

offer 在类中 DataQueue<E>

返回:

true if the element is added successfully; otherwise, the element is not added, return false.

                     TimeDuration timeout)
              throws InterruptedException

Adds an element to this queue, waiting up to the given timeout.

返回:

true if the element is added successfully; otherwise, the element is not added, return false.

抛出:

InterruptedException

poll

public E poll()

从类复制的说明: DataQueue

Poll out the head element from this queue.

覆盖:

poll 在类中 DataQueue<E>
