Constructor Detail

ConnectionOrientedMessageChannel

public ConnectionOrientedMessageChannel(SIPTransactionStack sipStack)

Method Detail

isReliable

public boolean isReliable()

Returns "true" as this is a reliable transport.

Specified by:

isReliable in class MessageChannel

Returns:

True if reliable, false if not.

close

public void close()

Close the message channel.

Specified by:

close in class MessageChannel

close

protected abstract void close(boolean removeSocket,
         boolean stopKeepAliveTask)

getSIPStack

public SIPTransactionStack getSIPStack()

Get my SIP Stack.

Specified by:

getSIPStack in class MessageChannel

Returns:

The SIP Stack for this message channel.

getPeerAddress

public String getPeerAddress()

get the address of the client that sent the data to us.

Specified by:

getPeerAddress in class MessageChannel

Returns:

Address of the client that sent us data that resulted in this channel being created.

getPeerInetAddress

protected InetAddress getPeerInetAddress()

Specified by:

getPeerInetAddress in class MessageChannel

getPeerProtocol

public String getPeerProtocol()

Specified by:

getPeerProtocol in class MessageChannel

sendMessage

public void sendMessage(SIPMessage sipMessage)
                 throws IOException

Return a formatted message to the client. We try to re-connect with the peer on the other end if possible.

Specified by:

sendMessage in class MessageChannel

Parameters:

sipMessage - Message to send.

Throws:

IOException - If there is an error sending the message

sendMessage

protected abstract void sendMessage(byte[] msg,
               boolean b)
                             throws IOException

Throws:

IOException

processMessage

public void processMessage(SIPMessage sipMessage,
                  InetAddress address)

processMessage

public void processMessage(SIPMessage sipMessage)
                    throws Exception

Gets invoked by the parser as a callback on successful message parsing (i.e. no parser errors).

Specified by:

processMessage in interface SIPMessageListener

Specified by:

processMessage in interface RawMessageChannel

Parameters:

sipMessage - Message to process (this calls the application for processing the message). Jvb: note that this code is identical to TCPMessageChannel, refactor some day

Throws:

Exception

See Also:

for the method that gets called on parse exception.

run

public void run()

This gets invoked when thread.start is called from the constructor. Implements a message loop - reading the tcp connection and processing messages until we are done or the other end has closed.

Specified by:

run in interface Runnable

uncache

protected void uncache()

Description copied from class: MessageChannel

Hook method, overridden by subclasses

Overrides:

uncache in class MessageChannel

getKey

public String getKey()

Get an identifying key. This key is used to cache the connection and re-use it if necessary.

Specified by:

getKey in class MessageChannel

getViaHost

public String getViaHost()

Get the host to assign to outgoing messages.

Specified by:

getViaHost in class MessageChannel

Returns:

the host to assign to the via header.

getViaPort

public int getViaPort()

Get the port for outgoing messages sent from the channel.

Specified by:

getViaPort in class MessageChannel

Returns:

the port to assign to the via header.

getPeerPort

public int getPeerPort()

Get the port of the peer to whom we are sending messages.

Specified by:

getPeerPort in class MessageChannel

Returns:

the peer port.

getPeerPacketSourcePort

public int getPeerPacketSourcePort()

Specified by:

getPeerPacketSourcePort in class MessageChannel

getPeerPacketSourceAddress

public InetAddress getPeerPacketSourceAddress()

Specified by:

getPeerPacketSourceAddress in class MessageChannel

                    throws Exception

Specified by:

sendSingleCLRF in interface SIPMessageListener

Throws:

Exception

public void cancelPingKeepAliveTimeoutTaskIfStarted()

setKeepAliveTimeout

public void setKeepAliveTimeout(long keepAliveTimeout)

getKeepAliveTimeout

public long getKeepAliveTimeout()

rescheduleKeepAliveTimeout
