public class Group
extends MetaPattern

A Group is a piece of a regular expression (referenced by some Java field or local variable) that forms a "capturing group" within the larger regular expression. A Group is bound to a regular expression MetaPattern when a matcher is retrieved for the pattern by calling one of the matcher() methods. Once bound, a Group cannot be rebound.
