Detailed Description

       Interface (envelope) to data received over RTP packets.

       A class of objects representing data transmitted over RTP packets. Tipically, this object
       will apply to received data. Data blocks received via RTP connections as well as its
       related objects (source, etc), are accessed through the methods of this class.

Constructor & Destructor Documentation

   AppDataUnit::AppDataUnit (const IncomingRTPPkt & packet, const SyncSource & src)
   AppDataUnit::~AppDataUnit () [inline]
   AppDataUnit::AppDataUnit (const AppDataUnit & src)
       Parameters:

Member Function Documentation

   uint8 AppDataUnit::getContributorsCount () const [inline]
       Get the number of contributing sources in the CSRC list.

   const uint32* AppDataUnit::getContributorsID () const [inline]
       Get the array of 32-bit CSRC identifiers.

       Returns:
           NULL if (getContributorsCount() == 0)

   const uint8* const AppDataUnit::getData () const [inline]
       Get data as it is received in RTP packets (i.e. for multi-octet encodings, octets are in
       network order.

       Returns:
           Raw pointer to data block.

       Examples:
           audiorx.cpp, ccrtptest.cpp, rtpduphello.cpp, and rtphello.cpp.

   uint16 AppDataUnit::getSeqNum () const [inline]
       Get data unit sequence number.

   size_t AppDataUnit::getSize () const [inline]
       Returns:
           length of data in octets

       Examples:
           audiorx.cpp, and rtplisten.cpp.

   const SyncSource& AppDataUnit::getSource () const [inline]
       Returns:
           Source that sent this data

       Examples:
           rtplisten.cpp.

   PayloadType AppDataUnit::getType () const [inline]
       Returns:
           type of this data

       Examples:
           rtplisten.cpp.

   bool AppDataUnit::isMarked () const [inline]
       Is this data unit marked?.

       Returns:
           true if marked.

   AppDataUnit& AppDataUnit::operator= (const AppDataUnit & source)
       Assignment operator.

       Parameters:
           source the AppDataUnit object being assigned

       Returns:
           the result of the assignment
