Package com.google.gerrit.sshd

Class ChannelIdTrackingUnknownChannelReferenceHandler

java.lang.Object

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

org.apache.sshd.common.session.helpers.DefaultUnknownChannelReferenceHandler

com.google.gerrit.sshd.ChannelIdTrackingUnknownChannelReferenceHandler

All Implemented Interfaces:

EventListener, org.apache.sshd.common.channel.ChannelListener, org.apache.sshd.common.session.UnknownChannelReferenceHandler, org.apache.sshd.common.util.SshdEventListener

public class ChannelIdTrackingUnknownChannelReferenceHandler
extends org.apache.sshd.common.session.helpers.DefaultUnknownChannelReferenceHandler
implements org.apache.sshd.common.channel.ChannelListener

Makes sure that the referenced "unknown" channel identifier is one that was assigned in the past. Note: it relies on the fact that the default ConnectionService implementation assigns channels identifiers in ascending order.
