All Implemented Interfaces:

Serializable

Direct Known Subclasses:

IOExceptionEventExt

public class IOExceptionEvent
extends EventObject

This object is used to signal to the application that an IO Exception has occured. The transaction state machine requires to report asynchronous IO Exceptions to the application immediately (according to RFC 3261). This class represents an IOExceptionEvent that is passed from a SipProvider to its SipListener. This event enables an implementation to propagate the asynchronous handling of IO Exceptions to the application. An application (SipListener) will register with the SIP protocol stack (SipProvider) and listen for IO Exceptions from the SipProvider. In many cases, when sending a SIP message, the sending function will return before the message was actually sent. This will happen for example if there is a need to wait for a response from a DNS server or to perform other asynchronous actions such as connecting a TCP connection. Later on if the message sending fails an IO exception event will be given to the application. IO Exception events may also be reported asynchronously when the Transaction State machine attempts to resend a pending request. Note that synchronous IO Exceptions are presented to the caller as SipException.

Constructor Detail

IOExceptionEvent

public IOExceptionEvent(Object source,
                String remoteHost,
                int port,
                String transport)

Constructor

Parameters:

source - -- the object that is logically deemed to have caused the IO Exception (dialog/transaction/provider).

remoteHost - -- host where the request/response was heading

port - -- port where the request/response was heading

transport - -- transport ( i.e. UDP/TCP/TLS).

Returns:

host

getPort

public int getPort()

Returns the port where the socket was trying to send amessage.

Returns:

port associated with the IOException

getTransport

public String getTransport()

Return transport used for the failed write attempt.

Returns:

the transaction associated with the IOException
