Class JsonTransformerResolver

java.lang.Object

org.mule.module.json.transformers.JsonTransformerResolver

All Implemented Interfaces:

MuleContextAware, Disposable, TransformerResolver

public class JsonTransformerResolver
extends Object
implements TransformerResolver, MuleContextAware, Disposable

A TransformerResolver implementation used to discover whether the current transform requests requires Json mashaling. The resolver will scan the source and return type for Jackson (http://jackson.codehaus.org) Json annotations and will configure a JSON transformer accordingly. The transformer is cached and will be used for any subsequent requests. The ObjectMapper instance needed for the transform can be discovered from the registry, this means one can be pre-configured in Spring or Guice. If there is no pre-configured ObjectMapper one will be created with the annotated JSON class. This context will cached with the transformer.
