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.
