Detailed Description

Default trace to send.

A trace based streamer.

Sends UDP packets based on a trace file of an MPEG4 stream trace files could be downloaded form: http://www2.tkn.tu-berlin.de/research/trace/ltvt.html (the 2 first lines of the file should be removed) A valid trace file is a file with 4 columns:

-1- the first one represents the frame index
-2- the second one indicates the type of the frame: I, P or B
-3- the third one indicates the time on which the frame was generated by the encoder
-4- the fourth one indicates the frame size in byte

If no valid MPEG4 trace file is provided to the application the trace from g_defaultEntries array will be loaded.

void ns3::UdpTraceClient::DoDispose ( void )

protectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.
