方法详细资料

getNextBuffer

@Nullable
public ResultSubpartition.BufferAndBacklog getNextBuffer()

从接口复制的说明: ResultSubpartitionView

Returns the next Buffer instance of this queue iterator.

If there is currently no instance available, it will return null. This might happen for example when a pipelined queue producer is slower than the consumer or a spilled queue needs to read in more data.

Important: The consumer has to make sure that each buffer instance will eventually be recycled with Buffer.recycleBuffer() after it has been consumed.
