use of org.jivesoftware.openfire.net.ClientStanzaHandler in project Openfire by igniterealtime.

the class ClientConnectionHandler method sessionIdle.

/**
	 * In addition to the functionality provided by the parent class, this
	 * method will send XMPP ping requests to the remote entity on every first
	 * invocation of this method (which will occur after a period of half the
	 * allowed connection idle time has passed, without any IO).
	 * 
	 * XMPP entities must respond with either an IQ result or an IQ error
	 * (feature-unavailable) stanza upon receiving the XMPP ping stanza. Both
	 * responses will be received by Openfire and will cause the connection idle
	 * count to be reset.
	 * 
	 * Entities that do not respond to the IQ Ping stanzas can be considered
	 * dead, and their connection will be closed by the parent class
	 * implementation on the second invocation of this method.
	 * 
	 * Note that whitespace pings that are sent by XMPP entities will also cause
	 * the connection idle count to be reset.
	 * 
	 * @see ConnectionHandler#sessionIdle(IoSession, IdleStatus)
