org.apache.ratis.util.DataQueue<E>

org.apache.ratis.util.DataBlockingQueue<E>

所有已实现的接口:

Iterable<E>

public class DataBlockingQueue<E>
extends DataQueue<E>

A queue for data elements such that the queue imposes limits on both number of elements and the data size in bytes. Null element is NOT supported. This class is threadsafe.

                         ToLongFunction<E> getNumBytes)

方法详细资料

getNumBytes

public long 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()

从类复制的说明: DataQueue

The same as Collection.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.

offer

public boolean offer(E element,
                     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

remove

public boolean remove(E e)

从类复制的说明: DataQueue

The same as Collection.remove(Object).

覆盖:

remove 在类中 DataQueue<E>

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>

poll

public E poll(TimeDuration timeout)
       throws InterruptedException

Poll out the head element from this queue, waiting up to the given timeout.

抛出:

InterruptedException

pollList

public <RESULT,THROWABLE extends Throwable> List<RESULT> pollList(long timeoutMs,
                                                                  CheckedFunctionWithTimeout<E,RESULT,THROWABLE> getResult,
