Annotation Type Union

@Retention(RUNTIME) @Target({TYPE,FIELD,PARAMETER,METHOD}) @Documented public @interface Union
Declares that a Java type should be represented by an Avro union schema. May be used for base classes or interfaces whose instantiable subclasses can be listed in the parameters to the @Union annotation. If applied to method parameters this determines the reflected message parameter type. If applied to a method, this determines its return type. A null schema may be specified with Void.
