Method Detail

parse

public BeanDefinition parse(org.w3c.dom.Element element,
                            ParserContext parserContext)
Description copied from interface: BeanDefinitionParser
Parse the specified Element and register the resulting BeanDefinition(s) with the BeanDefinitionRegistry embedded in the supplied ParserContext.

Implementations must return the primary BeanDefinition that results from the parse if they will ever be used in a nested fashion (for example as an inner tag in a <property/> tag). Implementations may return null if they will not be used in a nested fashion.

Specified by:
parse in interface BeanDefinitionParser
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; provides access to a BeanDefinitionRegistry
Returns:
the primary BeanDefinition
