Package org.apache.sshd.contrib.common.session.helpers

Class ChannelIdTrackingUnknownChannelReferenceHandler

  • All Implemented Interfaces:
    java.util.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.
