Encapsulates the prototyp for numerical parser functions. The class
|
|
stores the number of arguments for parser functions as well
|
|
as additional flags indication the function is non optimizeable.
|
|
The pointer to the callback function pointer is stored as void*
|
|
and needs to be casted according to the argument count.
|
|
Negative argument counts indicate a parser function with a variable number
|
|
of arguments.
