io.netty.channel.DefaultMaxMessagesRecvByteBufAllocator

io.netty.channel.FixedRecvByteBufAllocator

所有已实现的接口:

MaxMessagesRecvByteBufAllocator, RecvByteBufAllocator

public class FixedRecvByteBufAllocator
extends DefaultMaxMessagesRecvByteBufAllocator

The RecvByteBufAllocator that always yields the same buffer size prediction. This predictor ignores the feed back from the I/O thread.

构造器详细资料

FixedRecvByteBufAllocator

public FixedRecvByteBufAllocator(int bufferSize)

Creates a new predictor that always returns the same prediction of the specified buffer size.

方法详细资料

newHandle

public RecvByteBufAllocator.Handle newHandle()

从接口复制的说明: RecvByteBufAllocator

Creates a new handle. The handle provides the actual operations and keeps the internal information which is required for predicting an optimal buffer capacity.

respectMaybeMoreData

public FixedRecvByteBufAllocator respectMaybeMoreData(boolean respectMaybeMoreData)

从类复制的说明: DefaultMaxMessagesRecvByteBufAllocator

Determine if future instances of RecvByteBufAllocator.newHandle() will stop reading if we think there is no more data.

覆盖:

respectMaybeMoreData 在类中 DefaultMaxMessagesRecvByteBufAllocator

参数:

respectMaybeMoreData -

• true to stop reading if we think there is no more data. This may save a system call to read from the socket, but if data has arrived in a racy fashion we may give up our DefaultMaxMessagesRecvByteBufAllocator.maxMessagesPerRead() quantum and have to wait for the selector to notify us of more data.
• false to keep reading (up to DefaultMaxMessagesRecvByteBufAllocator.maxMessagesPerRead()) or until there is no data when we attempt to read.

返回:

this.
