Group (Wicket Util 9.0.0-SNAPSHOT API)

java.lang.Object
- org.apache.wicket.util.parse.metapattern.MetaPattern
- - org.apache.wicket.util.parse.metapattern.Group

All Implemented Interfaces:

java.io.Serializable, IClusterable

Direct Known Subclasses:

BooleanGroup, FloatingPointGroup, IntegerGroup
```
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.
