Class NioPipelineParser

java.lang.Object

android.gov.nist.javax.sip.parser.NioPipelineParser

public class NioPipelineParser
extends Object

This is a FSM that can parse a single stream of messages with they bodies and then pass the sip message to the listeners. It accumulates bytes until end of message is detected or some DoS trigger terminates it due to excessive amount of bytes per message or line. Once parsed it will pass the message to the SIPMessageListener

Field Detail

sipMessageListener

protected SIPMessageListener sipMessageListener

The message listener that is registered with this parser. (The message listener has methods that can process correct and erroneous messages.)

Constructor Detail

NioPipelineParser

protected NioPipelineParser()

default constructor.

NioPipelineParser

public NioPipelineParser(SIPTransactionStack sipStack,
                 SIPMessageListener sipMessageListener,
                 boolean debug,
                 int maxMessageSize)

Constructor when we are given a message listener and an input stream (could be a TCP connection or a file)

Parameters:

sipMessageListener - Message listener which has methods that get called back from the parser when a parse is complete

in - Input stream from which to read the input.

debug - Enable/disable tracing or lexical analyser switch.

NioPipelineParser

public NioPipelineParser(SIPTransactionStack sipStack,
                 SIPMessageListener mhandler,
                 int maxMsgSize)

This is the constructor for the pipelined parser.

Parameters:

mhandler - a SIPMessageListener implementation that provides the message handlers to handle correctly and incorrectly parsed messages.

in - An input stream to read messages from.

Method Detail

close

public void close()

readStream

public void readStream(InputStream inputStream)
                throws IOException

Throws:

IOException

processSIPMessage

public void processSIPMessage(SIPMessage message)

addBytes

public void addBytes(byte[] bytes)
              throws Exception

Throws:

Exception

setMessageListener

public void setMessageListener(SIPMessageListener mlistener)

Add a class that implements a SIPMessageListener interface whose methods get called * on successful parse and error conditons.

Parameters:

mlistener - a SIPMessageListener implementation that can react to correct and incorrect pars.
