Interface BeanDefinitionParser

All Known Implementing Classes:: AbstractBeanDefinitionParser, AbstractSimpleBeanDefinitionParser, AbstractSingleBeanDefinitionParser

public interface BeanDefinitionParser

Interface used by the DefaultBeanDefinitionDocumentReader to handle custom, top-level (directly under <beans>) tags.

Implementations are free to turn the metadata in the custom tag into as many BeanDefinitions as required.

The parser locates a BeanDefinitionParser from the associated NamespaceHandler for the namespace in which the custom tag resides.

Method Summary

BeanDefinition parse(Element element, ParserContext parserContext)
Parse the specified Element and register the resulting BeanDefinition(s) with the ParserContext.getRegistry() BeanDefinitionRegistry} embedded in the supplied ParserContext.

Method Summary
`BeanDefinition`	`parse(Element element, ParserContext parserContext)` Parse the specified `Element` and register the resulting `BeanDefinition(s)` with the `ParserContext.getRegistry()` BeanDefinitionRegistry} embedded in the supplied `ParserContext`.

Method Detail

parse

BeanDefinition parse(Element element,
                     ParserContext parserContext)

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.

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
