The Parser creates a mathematical Expression from a given input string.
It uses a Lexer to create a RPN token stream and then builds the expression.
Usage example:
Parser p = new Parser();
Expression exp = p.parse("(x^2 + cos(y)) / 3");

parse(
String inputString) → Expression -
Parses the given input string into an Expression. Throws a
ArgumentErrorif the giveninputStringis empty. Throws aStateErrorif the token stream is invalid. Returns a valid Expression. -
