Class TimeoutEvent

java.util.EventObject

android.javax.sip.TimeoutEvent

All Implemented Interfaces:

Serializable

public class TimeoutEvent
extends EventObject

This class represents an Timeout event that is passed from a SipProvider to its SipListener. A specific message may need retransmitted on a specific transaction numerous times before it is acknowledged by the receiver. If the message is not acknowledged after a specified period in the underlying implementation the transaction will expire, this occurs usually after seven retransmissions. The mechanism to alert an application that a message for a an underlying transaction needs retransmitted (i.e. 200OK) or an underlying transaction has expired is a Timeout Event.

A Timeout Event can be of two different types, namely:

• Timeout.RETRANSMIT
• Timeout.TRANSACTION

A TimeoutEvent contains the following information:

• source - the SipProvider that sent the TimeoutEvent.
• transaction - the transaction that this Timeout applies to.
• isServerTransaction - boolean indicating whether the transaction refers to a client or server transaction.
• timeout - indicates what type of Timeout occurred.
