HELP!: pointers on unsing expr: A.evaluate() && B.evaluate() || c.evaluate()

[Arman Anwar <aaanwar at yahoo dot com>]

Greetings All,

I need to implement an expression compiler that will copile boolean expressions into byte code.

The atoms in the expressions can be the true or flase values:

true && false

Or we could have methids that need to be evaluated on certain objects. For simplicities sake let us say all concerned objects implement the evaluate() method which returns a boolean result thus I would like to compile:

A.evaluate() && B.evaluate().

I can easily define the grammer using JavaCC and have a fair idea how to evaluate the resulting expressions.

I'd be mighty grateful for advise, wizedom and/or sample code.

TIA,

Arman.

    Is capable of achieving the impossible.
