Class SimplePropertyNamespaceHandler

    java.lang.Object
      org.springframework.beans.factory.xml.SimplePropertyNamespaceHandler

All Implemented Interfaces:
  NamespaceHandler

    public class SimplePropertyNamespaceHandler

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="rob" class="..TestBean" p:name="Rob Harrop" p:spouse-ref="sally"/>

Here the '`p:name`' corresponds directly to the '`name`' property on class '`TestBean`'. The '`p:spouse-ref`' attributes corresponds to the '`spouse`' property and, rather than being the concrete value, it contains the name of the bean that will be injected into that property.

  2.0

Constructor Summary
`SimplePropertyNamespaceHandler()`

Method Summary
`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`.

Constructor Detail

### SimplePropertyNamespaceHandler

    public SimplePropertyNamespaceHandler()

Method Detail

### init

    public void init()

  Description copied from interface: `NamespaceHandler`
  Invoked by the `DefaultBeanDefinitionDocumentReader` after construction but before any custom elements are parsed.

  Specified by:
    `init` in interface `NamespaceHandler`
  See Also:
    `NamespaceHandlerSupport.registerBeanDefinitionParser(String, BeanDefinitionParser)`

### parse

    public BeanDefinition parse(Element element,
                                ParserContext parserContext)

  Description copied from interface: `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.

  Specified by:
    `parse` in interface `NamespaceHandler`
  Parameters:
    `element` - the element that is to be parsed into one or more `BeanDefinitions`
    `parserContext` - the object encapsulating the current state of the parsing process
  Returns:
    the primary `BeanDefinition` (can be `null` as explained above)

### decorate

    public BeanDefinitionHolder decorate(Node node,
                                         BeanDefinitionHolder definition,
                                         ParserContext parserContext)

  Description copied from interface: `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.

  Specified by:
    `decorate` in interface `NamespaceHandler`
  Parameters:
    `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
  Returns:
    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.
