public BeanDefinition parse(Element element, ParserContext parserContext)

Implements org.springframework.beans.factory.xml.BeanDefinitionParser.parse.

Doc from org.springframework.beans.factory.xml.BeanDefinitionParser.parse.

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.

Parameters
element:Element

the element that is to be parsed into one or more BeanDefinitions

parserContext:ParserContext

the object encapsulating the current state of the parsing process; provides access to a org.springframework.beans.factory.support.BeanDefinitionRegistry

Returns:BeanDefinition

the primary BeanDefinition
