Class AbstractProviderConfigNamespaceHandler

java.lang.Object

org.springframework.social.config.xml.AbstractProviderConfigNamespaceHandler

All Implemented Interfaces:

NamespaceHandler

public abstract class AbstractProviderConfigNamespaceHandler
extends Object
implements NamespaceHandler

Base NamespaceHandler for Spring Social provider modules to create configuration namespaces. Requires, at minimum, that the provider-specific namespace provider an AbstractProviderConfigBeanDefinition for parsing "config" elements.

Method Detail

init

public final void init()

Specified by:

init in interface NamespaceHandler

parse

public final BeanDefinition parse(Element element,
                   ParserContext parserContext)

Specified by:

parse in interface NamespaceHandler

decorate

public BeanDefinitionHolder decorate(Node node,
                            BeanDefinitionHolder beanDefinitionHolder,
                            ParserContext parserContext)

Specified by:

decorate in interface NamespaceHandler

getProviderConfigBeanDefinitionParser

protected abstract AbstractProviderConfigBeanDefinitionParser getProviderConfigBeanDefinitionParser()

Implemented by provider namespaces to provide an instance of the bean definition parser that will parse the "config" element. This is the only configuration element required by a provider namespace. If a provider namespace offers additional elements, then their bean definition parsers may be registered by overriding the loadParsers() method.

Returns:

an instance of AbstractProviderConfigBeanDefinitionParser to register against the "config" element in the namespace.

loadParsers

protected void loadParsers(Map<String,BeanDefinitionParser> parsers)

Hook method to allow provider-specific implementation to register bean definition parsers for their namespace. An overriding method will simply add one or more bean definition parsers to the given map where the key is the name of the element the parser handles. Overriding this method is optional and there is no need to override it just to add the provider-specific implementation of AbstractProviderConfigBeanDefinitionParser. That bean definition parser will always be registered, whether or not this method is overridden.

Parameters:

parsers - a Map of parsers to be applied when parsing the namespace.
