public class ParenGroupIterator
extends AbstractPipeInputIterator

Iterator that takes a Reader, breaks up the input into top-level parenthesized expressions. For example, in the input (a (a b) c) f (d e), there are two top-level expressions '(a (a b) c)' and '(d e)'. Text that is not within parentheses is ignored. Created: Thu Feb 26 13:45:43 2004
