Annotation Interface DataTypeTransformer

@Retention(RUNTIME)

@ServiceFactory("transformer")
public @interface DataTypeTransformer

Marks a Transformer implementation as a data type transformer, identified by its name and/or its from/to DataTypes.

Classpath-scanning transformer loaders discover annotated classes and register them in the TransformerRegistry, so they can be detected and applied when a route declares input/output data types via a Contract. Provide a unique name(), or a fromType()/toType() pair, so the transformer can be referenced or auto-detected.

See Transformer in the Camel user manual.
