The evaluator package is designed to simplify the process of parsing a string.
The evaluator package is designed to simplify the process of parsing a string.
The work of parsing a string is reduced to just tokenizing an expression, that is, breaking it down into its principal parts. The AbstractEvaluator class will handle the rest.
The AbstractTokenizer makes this even easier, though it is only applicable in some situations.
