所有已实现的接口:
NamespaceHandler
```
public class SimpleConstructorNamespaceHandler
extends Object
implements NamespaceHandler
```
Simple NamespaceHandler implementation that maps custom attributes directly through to bean properties. An important point to note is that this NamespaceHandler does not have a corresponding schema since there is no way to know in advance all possible attribute names.
An example of the usage of this NamespaceHandler is shown below:
```
 <bean id="author" class="..TestBean" c:name="Enescu" c:work-ref="compositions"/>
 
```
Here the 'c:name' corresponds directly to the 'name ' argument declared on the constructor of class 'TestBean'. The 'c:work-ref' attributes corresponds to the 'work' argument and, rather than being the concrete value, it contains the name of the bean that will be considered as a parameter. Note: This implementation supports only named parameters - there is no support for indexes or types. Further more, the names are used as hints by the container which, by default, does type introspection.

`BeanDefinitionHolder`	`decorate(Node node, BeanDefinitionHolder definition, ParserContext parserContext)`	Parse the specified `Node` and decorate the supplied `BeanDefinitionHolder`, returning the decorated definition.
`void`	`init()`	Invoked by the `DefaultBeanDefinitionDocumentReader` after construction but before any custom elements are parsed.
`BeanDefinition`	`parse(Element element, ParserContext parserContext)`	Parse the specified `Element` and register any resulting `BeanDefinitions` with the `BeanDefinitionRegistry` that is embedded in the supplied `ParserContext`.

    从接口复制的说明: NamespaceHandler
    Invoked by the DefaultBeanDefinitionDocumentReader after construction but before any custom elements are parsed.
    指定者:
    init 在接口中 NamespaceHandler

    NamespaceHandlerSupport.registerBeanDefinitionParser(String, BeanDefinitionParser)
  - parse
```
public BeanDefinition parse(Element element,
                            ParserContext parserContext)
```
    从接口复制的说明: NamespaceHandler
    Parse the specified Element and register any resulting BeanDefinitions with the BeanDefinitionRegistry that is embedded in the supplied ParserContext.
    Implementations should return the primary BeanDefinition that results from the parse phase if they wish to be used nested inside (for example) a <property> tag.
    Implementations may return null if they will not be used in a nested scenario.
    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)
```
    从接口复制的说明: NamespaceHandler
    Parse the specified Node and decorate the supplied BeanDefinitionHolder, returning the decorated definition.
    The Node may be either an Attr or an Element, depending on whether a custom attribute or element is being parsed.
    Implementations may choose to return a completely new definition, which will replace the original definition in the resulting BeanFactory.
    The supplied ParserContext can be used to register any additional beans needed to support the main definition.
    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.
