类 WriteBufferWaterMark

java.lang.Object

io.netty.channel.WriteBufferWaterMark

public final class WriteBufferWaterMark
extends java.lang.Object

WriteBufferWaterMark is used to set low water mark and high water mark for the write buffer.

If the number of bytes queued in the write buffer exceeds the high water mark, Channel.isWritable() will start to return false.

If the number of bytes queued in the write buffer exceeds the high water mark and then dropped down below the low water mark, Channel.isWritable() will start to return true again.

Note that messages needs to be handled by the MessageSizeEstimator used by the channel for Channel.isWritable() to provide accurate back-pressure.
