Class LocalWindow

org.apache.sshd.common.util.logging.AbstractLoggingBean

org.apache.sshd.common.channel.Window

org.apache.sshd.common.channel.LocalWindow

All Implemented Interfaces:

Closeable, AutoCloseable, ChannelHolder

public class LocalWindow
extends Window

A Window that describes how much data this side is prepared to receive from the peer. Initialized when the channel is created. This side reduces the window by the amount of data received on reception; if it receives more data than allowed, it closes the channel. Once the data received has been processed, for instance, passed on, this side checks the current window size and if it is low, increases it and sends an SSH_MSG_CHANNEL_WINDOW_ADJUST message to the peer, who then is allowed to send more data again.
