Class AbstractRulesImpl

java.lang.Object
  org.apache.commons.digester3.AbstractRulesImpl

All Implemented Interfaces:

Rules

Direct Known Subclasses:

RegexRules, RulesBase

public abstract class AbstractRulesImpl
extends Object
implements Rules

AbstractRuleImpl provides basic services for Rules implementations. Extending this class should make it easier to create a Rules implementation.

AbstractRuleImpl manages the Digester and namespaceUri properties. If the subclass overrides registerRule(java.lang.String, org.apache.commons.digester3.Rule) (rather than add(java.lang.String, org.apache.commons.digester3.Rule)), then the Digester and namespaceURI of the Rule will be set correctly before it is passed to registerRule. The subclass can then perform whatever it needs to do to register the rule.

Since:

1.5

Method Detail

getDigester

public Digester getDigester()

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

Specified by:

getDigester in interface Rules

Returns:

the Digester instance with which this Rules instance is associated

setDigester

public void setDigester(Digester digester)

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

Specified by:

setDigester in interface Rules

Parameters:

digester - The newly associated Digester instance

getNamespaceURI

public String getNamespaceURI()

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

Specified by:

getNamespaceURI in interface Rules

Returns:

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

setNamespaceURI

public void setNamespaceURI(String namespaceURI)

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

Specified by:

setNamespaceURI in interface Rules

Parameters:

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

add

public final void add(String pattern,
                      Rule rule)

Register a new Rule instance matching the specified pattern.

Specified by:

add in interface Rules

Parameters:

pattern - Nesting pattern to be matched for this Rule

rule - Rule instance to be registered

registerRule

protected abstract void registerRule(String pattern,
                                     Rule rule)

Register rule at given pattern. The the Digester and namespaceURI properties of the given Rule can be assumed to have been set properly before this method is called.

Parameters:

pattern - Nesting pattern to be matched for this Rule

rule - Rule instance to be registered
