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:

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

Also note that:

The latter behavior can be changed through the "TraceLoop" attribute.

Member Function Documentation

◆ DoDispose()

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 overridden 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.

Reimplemented from ns3::Application.
