Interface HasAnnotations

All Known Subinterfaces:
JAbstractMethod, JAnnotationMethod, JAnnotationType, JArrayType, JClassType, JConstructor, JEnumConstant, JEnumType, JField, JGenericType, JMethod, JPackage, JParameter, JParameterizedType, JRawType, JRealClassType, JTypeParameter, JWildcardType
public interface HasAnnotations
Interface implemented by elements that can have annotations. This interface is a departure for GWT in that it used types declared in the java.lang.annotation package instead of types declared as part of this typeinfo package. This reflects a compromise between a pure TypeOracle model and one that is more useful to developers.
