Public Member Functions
ShBlockListPtr	blockList ()
	Get the currently active list.

These should always be called together, like so: pushArgQueue() && pushArg() && processArg(foo) && pushArg() && processArg(bar)
bool	pushArgQueue ()
bool	pushArg ()
	Indicate that an argument is coming. Always returns true.
bool	processArg (const ShVariable &result)
	Tokenize an argument, then add it to the argument queue. Always returns true.
Retrieving arguments
ShTokenArgument	getArgument ()
void	popArgQueue ()
	Pop the argument context (call after you've retrieved all your arguments).

Detailed Description

A tokenizer.

This is used during construction of the program, i.e. within a BeginShader/EndShader block, to process control statements in a tokenized fashion.

Once the shader has been parsed there is no more need for the tokenizer.
