public abstract class NamespaceHandlerSupport
extends Object
implements NamespaceHandler
```
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.
从以下版本开始:
2.0

所有方法实例方法具体方法
修饰符和类型	方法	说明
`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.

  - parse
```
public BeanDefinition parse(Element element,
                            ParserContext parserContext)
```
    Parses the supplied Element by delegating to the BeanDefinitionParser that is registered for that Element.
    指定者:
    parse 在接口中 NamespaceHandler
    参数:
    element - the element that is to be parsed into one or more BeanDefinitions
    parserContext - the object encapsulating the current state of the parsing process
    返回:
    the primary BeanDefinition (can be null as explained above)
  - decorate
```
public BeanDefinitionHolder decorate(Node node,
                                     BeanDefinitionHolder definition,
                                     ParserContext parserContext)
```
    Decorates the supplied Node by delegating to the BeanDefinitionDecorator that is registered to handle that Node.
    指定者:
    decorate 在接口中 NamespaceHandler
    参数:
    node - the source element or attribute that is to be parsed
    definition - the current bean definition
    parserContext - the object encapsulating the current state of the parsing process
    返回:
    the decorated definition (to be registered in the BeanFactory), or simply the original bean definition if no decoration is required. A null value is strictly speaking invalid, but will be leniently treated like the case where the original bean definition gets returned.
  - registerBeanDefinitionParser
```
protected final void registerBeanDefinitionParser(String elementName,
                                                  BeanDefinitionParser parser)
```
    Subclasses can call this to register the supplied BeanDefinitionParser to handle the specified element. The element name is the local (non-namespace qualified) name.
  - registerBeanDefinitionDecorator
```
protected final void registerBeanDefinitionDecorator(String elementName,
                                                     BeanDefinitionDecorator dec)
```
    Subclasses can call this to register the supplied BeanDefinitionDecorator to handle the specified element. The element name is the local (non-namespace qualified) name.
  - registerBeanDefinitionDecoratorForAttribute
```
protected final void registerBeanDefinitionDecoratorForAttribute(String attrName,
                                                                 BeanDefinitionDecorator dec)
```
    Subclasses can call this to register the supplied BeanDefinitionDecorator to handle the specified attribute. The attribute name is the local (non-namespace qualified) name.
