## org.mule.config.transformer
Class AbstractAnnotatedTransformerArgumentResolver

    java.lang.Object
      org.mule.config.transformer.AbstractAnnotatedTransformerArgumentResolver

All Implemented Interfaces:
  Disposable, TransformerArgumentResolver

Direct Known Subclasses:
  JAXBContextResolver, JsonMapperResolver

    public abstract class AbstractAnnotatedTransformerArgumentResolver

extends Object
implements TransformerArgumentResolver, Disposable

An abstract resolver that can be extend to resolve/create an object based on Annotated classes. These classes can be scanned and used to create the context. Typically this class will be used to create resolvers for binding frameworks where the data type classes are annotated with binding information.

### AbstractAnnotatedTransformerArgumentResolver

    public AbstractAnnotatedTransformerArgumentResolver()

Method Detail

### resolve

    public <T> T resolve(Class<T> type,
                         DataType source,
                         DataType result,
                         MuleContext context)
              throws Exception

  Specified by:
    `resolve` in interface `TransformerArgumentResolver`
  Throws:
    `Exception`

### findAnnotation

    protected boolean findAnnotation(Class annotatedType)
                              throws IOException

  Throws:
    `IOException`

### isNonMatching

    protected boolean isNonMatching(DataType source,
                                    DataType result)

### dispose

    public void dispose()

  Description copied from interface: `Disposable`
  A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

  Specified by:
    `dispose` in interface `Disposable`

### getMatchingClasses

    public Set<Class> getMatchingClasses()

### getNonMatchingClasses

    public Set<Class> getNonMatchingClasses()

### getArgumentClass

    protected abstract Class getArgumentClass()

  The object type that this resolver will discover or create

  Returns:
    The object type that this resolver will discover or create

### createArgument

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

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

  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 abstract String getAnnotationsPackageName()

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

  Returns:
    the package of the annotation(s) to scan for
