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 ParserContext.getRegistry() 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
