## org.mule.config.spring.parsers.generic
Class OptionalChildDefinitionParser

    java.lang.Object
      org.springframework.beans.factory.xml.AbstractBeanDefinitionParser
          org.mule.config.spring.parsers.AbstractMuleBeanDefinitionParser
              org.mule.config.spring.parsers.AbstractHierarchicalDefinitionParser
                  org.mule.config.spring.parsers.AbstractChildDefinitionParser
                      org.mule.config.spring.parsers.generic.ChildDefinitionParser
                          org.mule.config.spring.parsers.generic.OptionalChildDefinitionParser

All Implemented Interfaces:
  MuleChildDefinitionParser, MuleDefinitionParser, MuleDefinitionParserConfiguration, org.springframework.beans.factory.xml.BeanDefinitionParser

Direct Known Subclasses:
  ScriptDefinitionParser

    public class OptionalChildDefinitionParser

extends ChildDefinitionParser

This class should be used when the same element can be configured as a child or an orphan (i.e., top-level). It will inject the bean into the parent if the parent exists, otherwise it will not complain (ChildDefinitionParser throws an exception if no parent exists).
