The main class used to parse an input string when given a language.

Specifically, this class contains a ParseData object and is responsible for parsing an input string. This it does via its Language class and the Language included ParseTypes. In particular, while data remains to be parsed in the input string, the Parser uses Language to find the proper ParseType. It then calls this ParseType on the ParseData to parse one object. After parsing is complete, the Parser does some upkeep on the Operators and returns the resulting Node at the top of the Node stack.

Code:

public ~ Parser ( )

The only constructor for this class; accepts a Language pointer.

The language pointer is essential to the Parser because it defines the ParseTypes which need to be used to transform the data from string to Node stack.

Code:

public Parser (

const Parser & )

Returns a pointer to the ParseData structure in the Parser.

This function allows extension of the Parser by allowing more open access to the data included during parsing.

The main parsing function.

Performs a complete parsing of the string (according to the current Language. It then performs slight upkeep and returns the Node left at the top of the Node stack. If the stack is left empty, returns NULL.
