Member Function Documentation

list< Frame * > Forwarder::adapt (  Frame *  frm  )  [inline, virtual]
 

Accepts as input a frame, and checks if it can adapt the frame, If the frame is modified, a new Frame object is created and inserted into the return list.

This new frame is returned only, if the size of the payload is larger than zero. If the frame was not modified, it is also inserted into the list. For more complex adaptors, it will happen, that the adaptor caches up one complete GOP and returns the full GOP in network order. A caching adaptor has to create deep-copies for each frames. Never directly modify the payload of the input frm, always create copies!!!

Parameters:
frm object to adapt. An Adaptor is never allowed to free the input frame. This has to be done in the caller.
Returns:
List of adapted Frame objects

Reimplemented from Adaptor.

00067         };

Adaptor* Forwarder::clone (   )  [inline, virtual]
 

Create a shallow copy of the Adaptor.

Creates an Adaptor with the same setup (without copying the current status).

Returns:
An Adaptor object.

Implements Adaptor.

void Forwarder::initialize (   )  [inline, virtual]
 

Initialize internal data structures.

void Forwarder::setESInfo (  ESInfo *  esi  )  [inline, virtual]
 

Sets a reference to an ESInfo object.

Adaptors are allowed to change ESInfo objects. If you don't want that, pass an es->clone()
