Class RegexUrlMapping

java.lang.Object

org.codehaus.groovy.grails.web.mapping.AbstractUrlMapping

org.codehaus.groovy.grails.web.mapping.RegexUrlMapping

All Implemented Interfaces:

java.lang.Comparable, UrlCreator, UrlMapping

public class RegexUrlMapping
extends AbstractUrlMapping

A UrlMapping implementation that takes a Grails URL pattern and turns it into a regex matcher so that URLs can be matched and information captured from the match.

A Grails URL pattern is not a regex, but is an extension to the form defined by Apache Ant and used by Spring AntPathMatcher. Unlike regular Ant paths Grails URL patterns allow for capturing groups in the form:

/blog/(*)/**

The parenthesis define a capturing group. This implementation transforms regular Ant paths into regular expressions that are able to use capturing groups

Since:

0.5
