Method Detail

shouldGenerateId

protected boolean shouldGenerateId()

Description copied from class: AbstractBeanDefinitionParser

Should an ID be generated instead of read from the passed in Element?

Disabled by default; subclasses can override this to enable ID generation. Note that this flag is about always generating an ID; the parser won't even check for an "id" attribute in this case.

Overrides:

shouldGenerateId in class AbstractBeanDefinitionParser

Returns:

whether the parser should always generate an id

getBeanClassName

protected java.lang.String getBeanClassName(org.w3c.dom.Element element)

Description copied from class: AbstractSingleBeanDefinitionParser

Determine the bean class name corresponding to the supplied Element.

Overrides:

getBeanClassName in class AbstractSingleBeanDefinitionParser

Parameters:

element - the Element that is being parsed

Returns:

the class name of the bean that is being defined via parsing the supplied Element, or null if none

See Also:

AbstractSingleBeanDefinitionParser.getBeanClass(org.w3c.dom.Element)

doParse

protected void doParse(org.w3c.dom.Element element,
                       ParserContext parserContext,
                       BeanDefinitionBuilder builder)

Description copied from class: AbstractSingleBeanDefinitionParser

Parse the supplied Element and populate the supplied BeanDefinitionBuilder as required.

The default implementation delegates to the doParse version without ParserContext argument.

Overrides:

doParse in class AbstractSingleBeanDefinitionParser

Parameters:

element - the XML element being parsed

parserContext - the object encapsulating the current state of the parsing process

builder - used to define the BeanDefinition

AbstractSingleBeanDefinitionParser.doParse(Element, BeanDefinitionBuilder)
