Package org.apache.struts2.convention

Class ActionNameSpecificityComparator

java.lang.Object

org.apache.struts2.convention.ActionNameSpecificityComparator

All Implemented Interfaces:

Comparator<String>

public class ActionNameSpecificityComparator
extends Object
implements Comparator<String>

Orders wildcard action-name patterns most-specific-first so that, under the framework's first-match-wins matching, a specific pattern (e.g. some/usefull/*) is evaluated before a general one (e.g. some/*).

Ordering keys, applied in order:

1. fewer wildcard tokens first (a */** run, or a {var} group);
2. more literal characters first;
3. fewer path-spanning ** tokens first;
4. natural (alphabetical) order of the pattern, for deterministic tie-breaking.

Matcher-agnostic: it recognises both */** (WildcardHelper) and {var} (NamedVariablePatternMatcher) wildcards.

Since:

7.3.0 (WW-3784)
