Examples of org.mule.impl.model.resolvers.AnnotatedEntryPointResolver

org.mule.impl.model.resolvers.AnnotatedEntryPointResolver
uff } The component method above will be invoked by running the XPath expression on the payload, adding a second parameter as the payload itself and passing in the header 'name' as the third parameter. There are some rules for how components with annotations will be processed -
- For components with more than one method annotated with Mule expression annotations the method name to call needs to be set on the incoming message or endpoint using the {@link org.mule.api.config.MuleProperties#MULE_METHOD_PROPERTY} key.
- If the component has only one method annotated with Mule expression annotations there is no need to set the method name to invoke
- Every parameter on the method needs to be annotated
