/**
|
|
* This is the main class for RenderMonkey file (.rfx) Xml Parser.
|
|
* A RenderMonkey file can contain any number of RmOpenGLEffect, each of which can
|
|
* contain any number of RmGLPass. Not all the pass have a fragment or vertex
|
|
* program, so we ignore the one that do not have them
|
|
* It works on a file corresponding to the given file name and the parsing
|
|
* is invoked by calling parse(). On success, this is the tree of class
|
|
* collected by the parser:
|
|
*
|
|
* RmXmlParser:
|
|
* - List< RmEffect >, each RmEffect has:
|
|
* - List< RmPass >, each RmPass has:
|
|
* - the fragment program source code
|
|
* - the vertex program source code
|
|
* - the uniform variable used in the fragment program
|
|
* - the uniform variable used in the vertex program
|
|
* - other infos such as openGL state and model reference
|
|
*
|
|
* Any class that is a container of List< other class > has these three methods:
|
|
* - int size() to know the list size
|
|
* - T & at(int idx) to get the idx-th element of the list
|
|
* - T & operator[] (int idx) as above
