Description

Interface to the processing nodes and the render nodes network.

Actually, there are three different interfaces to consider

• the ProcNode::pull is the invocation interface. It is call-style (easily callable by C)
• the builder interface, comprised by the NodeFactory and the WiringFactory. It's C++ (using templates)
• the actual processing function is supposed to be a C function; it uses a set of C functions for accessing the frame buffers with the data to be processed.

By using the builder interface, concrete node and wiring descriptor classes are created, based on some templates. These concrete classes form the "glue" to tie the node network together and contain much of the operation behaviour in a hard wired fashion.
