public final class AiccPrerequisiteParser
extends Object

A utility class for parsing AICC prerequisite expressions into structured representations. The class provides functionality to tokenize, validate, and process prerequisite strings into a format suitable for further evaluation or manipulation.

This class uses methods to convert the input expression into tokens, rearrange them into postfix notation, construct an Abstract Syntax Tree (AST), and extract identifiers from the expression. The class supports operators such as "AND", "OR", and "NOT", as well as optional markers for dependencies.
