public class RulesBase extends Object implements Rules
Default implementation of the Rules interface that supports
 the standard rule matching behavior.  This class can also be used as a
 base class for specialized Rules implementations.
The matching policies implemented by this class support two different types of pattern matching rules:
<c> element, nested inside a <b>
     element, which is nested inside an <a> element.<b> element, nested inside an <a>
      element, no matter how deeply the pair is nested.| Modifier and Type | Field and Description | 
|---|---|
| protected HashMap<String,List<Rule>> | cacheThe set of registered Rule instances, keyed by the matching pattern. | 
| protected Digester | digesterThe Digester instance with which this Rules instance is associated. | 
| protected String | namespaceURIThe namespace URI for which subsequently added  Ruleobjects are relevant, ornullfor matching independent
 of namespaces. | 
| protected ArrayList<Rule> | rulesThe set of registered Rule instances, in the order that they were
 originally registered. |

| void | add(String pattern,
   Rule rule)Register a new Rule instance matching the specified pattern. | 
| void | clear()Clear all existing Rule instance registrations. | 
| Digester | getDigester()Return the Digester instance with which this Rules instance is
 associated. | 
| String | getNamespaceURI()Return the namespace URI that will be applied to all subsequently
 added  Ruleobjects. | 
| protected List<Rule> | lookup(String namespaceURI,
      String pattern)Return a List of Rule instances for the specified pattern that also
 match the specified namespace URI (if any). | 
| List<Rule> | match(String namespaceURI,
     String pattern)Return a List of all registered Rule instances that match the specified
 nesting pattern, or a zero-length List if there are no matches. | 
| List<Rule> | rules()Return a List of all registered Rule instances, or a zero-length List
 if there are no registered Rule instances. | 
| void | setDigester(Digester digester)Set the Digester instance with which this Rules instance is associated. | 
| void | setNamespaceURI(String namespaceURI)Set the namespace URI that will be applied to all subsequently
 added  Ruleobjects. |
