Sequence

Class Overview

The Sequence parser matches if its left parser matches the prefix of the parse buffer and then its right parser matches (in sequence) the prefix of whatever remains in the parse buffer. Contrast this with the Alternative and Intersection parsers which apply their sub-parsers to the same portion of the parse buffer. The following matches a string composed of letters followed by digits: Parser p = Parser.sequence(Chset.ALPHA.plus(), Chset.DIGIT.plus()); p.parse("a0") -> matches "a0" p.parse("aaa0") -> matches "aaa0" p.parse("aaa000") -> matches "aaa0000" p.parse("a1a") -> matches "a1" p.parse("a") -> no match, does not end in a digit p.parse("0") -> no match, does not start with a letter
