  org.mule.config.transformer.AbstractAnnotatedTransformerArgumentResolver
      org.mule.module.xml.transformer.jaxb.JAXBContextResolver

All Implemented Interfaces:

Disposable, TransformerArgumentResolver

public class JAXBContextResolver
extends AbstractAnnotatedTransformerArgumentResolver

This resolver is used by the transform engine to inject a JAXBContext into a method that requires it. A shared JAXB context can be created for the application and stored in the registry, this will get injected into any transform methods that add JAXBContext to the method signature.

IF there is no shared JAXB context one will be created. First this resolver will attempt to create the context from the package of the the annotated class, for this to work either a jaxb.index file must be present or an ObjectFactory must be in the package. This allows for JAXB generated classes to be used easily. If this method fails a context will be created using just the annotated class to initialise the context.

Method Detail

getArgumentClass

protected Class getArgumentClass()

Description copied from class: AbstractAnnotatedTransformerArgumentResolver

The object type that this resolver will discover or create

Specified by:

getArgumentClass in class AbstractAnnotatedTransformerArgumentResolver

Returns:

The object type that this resolver will discover or create

createArgument

protected Object createArgument(Class annotatedType,
                                MuleContext muleContext)
                         throws Exception

Description copied from class: AbstractAnnotatedTransformerArgumentResolver

If the resolver cannot locate the required object of type AbstractAnnotatedTransformerArgumentResolver.getArgumentClass() this method will be invoked an instance of the object.

Specified by:

createArgument in class AbstractAnnotatedTransformerArgumentResolver

Parameters:

annotatedType - the annotated object that was matched

muleContext - the current Mule context.

Returns:

a new instance of the object being resolved. This method may also retain a shared instance and possible add configuration to the instance based on this invocation

Throws:

Exception - if the object cannot be created

getAnnotationsPackageName

protected String getAnnotationsPackageName()

Description copied from class: AbstractAnnotatedTransformerArgumentResolver

This resolver scans a class for annotations in this package. Note this behaviour can be changed by overloading the AbstractAnnotatedTransformerArgumentResolver.findAnnotation(Class) method and search based on your own criteria

Specified by:

getAnnotationsPackageName in class AbstractAnnotatedTransformerArgumentResolver

Returns:

the package of the annotation(s) to scan for
