java.lang.Objectcom.opensymphony.xwork2.config.impl.ActionConfigMatcher
public class ActionConfigMatcher
Matches paths against pre-compiled wildcard expressions pulled from action configs. It uses the wildcard matcher from the Apache Cocoon project. Patterns will be matched in the order they exist in the config file. The first match wins, so more specific patterns should be defined before less specific patterns.

public ActionConfigMatcher(Map<String,ActionConfig> configs)
Finds and precompiles the wildcard patterns from the ActionConfig "path" attributes. ActionConfig's will be evaluated in the order they exist in the config file. Only paths that actually contain a wildcard will be compiled. Patterns will matched strictly.

Finds and precompiles the wildcard patterns from the ActionConfig "path" attributes. ActionConfig's will be evaluated in the order they exist in the config file. Only paths that actually contain a wildcard will be compiled.
Patterns can optionally be matched "loosely". When the end of the pattern matches \*[^*]\*$ (wildcard, no wildcard, wildcard), if the pattern fails, it is also matched as if the last two characters didn't exist. The goal is to support the legacy "*!*" syntax, where the "!*" is optional.
