All Known Implementing Classes:

AbstractRulesImpl, ExtendedBaseRules, PluginRules, RegexRules, RulesBase, WithDefaultsRulesWrapper

public interface Rules

Public interface defining a collection of Rule instances (and corresponding matching patterns) plus an implementation of a matching policy that selects the rules that match a particular pattern of nested elements discovered during parsing.

Method Summary

Modifier and Type	Method	Description
void	add(java.lang.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.
java.lang.String	getNamespaceURI()	Return the namespace URI that will be applied to all subsequently added Rule objects.
java.util.List<Rule>	match(java.lang.String pattern)	Deprecated. Call match(namespaceURI,pattern) instead.
java.util.List<Rule>	match(java.lang.String namespaceURI, java.lang.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.
java.util.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(java.lang.String namespaceURI)	Set the namespace URI that will be applied to all subsequently added Rule objects.

Method Detail

getDigester

Digester getDigester()

Return the Digester instance with which this Rules instance is associated.

setDigester

void setDigester(Digester digester)

Set the Digester instance with which this Rules instance is associated.

Parameters:

digester - The newly associated Digester instance

getNamespaceURI

java.lang.String getNamespaceURI()

Return the namespace URI that will be applied to all subsequently added Rule objects.

setNamespaceURI

void setNamespaceURI(java.lang.String namespaceURI)

Set the namespace URI that will be applied to all subsequently added Rule objects.

Parameters:

namespaceURI - Namespace URI that must match on all subsequently added rules, or null for matching regardless of the current namespace URI

add

void add(java.lang.String pattern,
         Rule rule)

Register a new Rule instance matching the specified pattern.

Parameters:

pattern - Nesting pattern to be matched for this Rule

rule - Rule instance to be registered

clear

void clear()

Clear all existing Rule instance registrations.

match

@Deprecated
java.util.List<Rule> match(java.lang.String pattern)

Deprecated. Call match(namespaceURI,pattern) instead.

Return a List of all registered Rule instances that match the specified nesting pattern, or a zero-length List if there are no matches. If more than one Rule instance matches, they must be returned in the order originally registered through the add() method.

Parameters:

pattern - Nesting pattern to be matched

match

java.util.List<Rule> match(java.lang.String namespaceURI,
                           java.lang.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. If more than one Rule instance matches, they must be returned in the order originally registered through the add() method.

Parameters:

namespaceURI - Namespace URI for which to select matching rules, or null to match regardless of namespace URI

pattern - Nesting pattern to be matched

rules

java.util.List<Rule> rules()

Return a List of all registered Rule instances, or a zero-length List if there are no registered Rule instances. If more than one Rule instance has been registered, they must be returned in the order originally registered through the add() method.
