public abstract class NamespaceHandlerSupport extends Object implements NamespaceHandler
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.

| Modifier and Type | Method and Description |
|---|---|
BeanDefinitionHolder |
decorate(Node node,
BeanDefinitionHolder definition,
ParserContext parserContext)
Decorates the supplied
Node by delegating to the BeanDefinitionDecorator that
is registered to handle that Node. |
BeanDefinition |
parse(Element element,
ParserContext parserContext)
Parses the supplied
Element by delegating to the BeanDefinitionParser that is
registered for that Element. |
protected void |
registerBeanDefinitionDecorator(String elementName,
BeanDefinitionDecorator dec)
Subclasses can call this to register the supplied
BeanDefinitionDecorator to
handle the specified element. |
protected void |
registerBeanDefinitionDecoratorForAttribute(String attrName,
BeanDefinitionDecorator dec)
Subclasses can call this to register the supplied
BeanDefinitionDecorator to
handle the specified attribute. |
protected void |
registerBeanDefinitionParser(String elementName,
BeanDefinitionParser parser)
Subclasses can call this to register the supplied
BeanDefinitionParser to
handle the specified element. |
