构造器详细资料

BufferManager

public BufferManager(org.apache.flink.core.memory.MemorySegmentProvider globalPool,
                     InputChannel inputChannel,
                     int numRequiredBuffers)

方法详细资料

recycle

public void recycle(org.apache.flink.core.memory.MemorySegment segment)

Exclusive buffer is recycled to this channel manager directly and it may trigger return extra floating buffer based on numRequiredBuffers.

指定者:

recycle 在接口中 BufferRecycler

参数:

segment - The exclusive segment of this channel.

notifyBufferAvailable

public boolean notifyBufferAvailable(Buffer buffer)

The buffer pool notifies this listener of an available floating buffer. If the listener is released or currently does not need extra buffers, the buffer should be returned to the buffer pool. Otherwise, the buffer will be added into the bufferQueue.

指定者:

notifyBufferAvailable 在接口中 BufferListener

参数:

buffer - Buffer that becomes available in buffer pool.

返回:

true if the buffer is accepted by this listener.

notifyBufferDestroyed

public void notifyBufferDestroyed()

从接口复制的说明: BufferListener

Notification callback if the buffer provider is destroyed.

指定者:

notifyBufferDestroyed 在接口中 BufferListener
