Example 11 with Connection

use of org.jivesoftware.openfire.Connection 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)
