public abstract class NamespaceHandlerSupport
Support class for implementing custom NamespaceHandlers.
Parsing and decorating of individual Nodes is done via BeanDefinitionParser
and BeanDefinitionDecorator strategy interfaces, respectively.
Provides the registerBeanDefinitionParser(java.lang.String, org.springframework.beans.factory.xml.BeanDefinitionParser) and registerBeanDefinitionDecorator(java.lang.String, org.springframework.beans.factory.xml.BeanDefinitionDecorator)
methods for registering a BeanDefinitionParser or BeanDefinitionDecorator
to handle a specific element.

public BeanDefinition parse(Element element,
ParserContext parserContext)
Element by delegating to the BeanDefinitionParser that is
registered for that Element.
parse in interface NamespaceHandlerelement - the element that is to be parsed into one or more BeanDefinitionsparserContext - the object encapsulating the current state of the parsing process
BeanDefinition (can be null as explained above)
public BeanDefinitionHolder decorate(Node node,
BeanDefinitionHolder definition,
ParserContext parserContext)
Node by delegating to the BeanDefinitionDecorator that
is registered to handle that Node.
decorate in interface NamespaceHandlernode - the source element or attribute that is to be parseddefinition - the current bean definitionparserContext - the object encapsulating the current state of the parsing process
null value is strictly speaking invalid, but will be leniently
treated like the case where the original bean definition gets returned.
protected final void registerBeanDefinitionParser(String elementName,
BeanDefinitionParser parser)
BeanDefinitionParser to
handle the specified element. The element name is the local (non-namespace qualified)
name.
protected final void registerBeanDefinitionDecorator(String elementName,
BeanDefinitionDecorator dec)
BeanDefinitionDecorator to
handle the specified element. The element name is the local (non-namespace qualified)
name.
protected final void registerBeanDefinitionDecoratorForAttribute(String attrName,
BeanDefinitionDecorator dec)
BeanDefinitionDecorator to
handle the specified attribute. The attribute name is the local (non-namespace qualified)
name.
