HasAnnotations (GWT Javadoc)

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.

  - getAnnotation
```
<T extends java.lang.annotation.Annotation> T getAnnotation(java.lang.Class<T> annotationClass)
```
    Returns an instance of the specified annotation type if it is present on this element or null if it is not. For a class, this will look for annotations on supertypes as well.
    
    Parameters:
    
    annotationClass - annotation type to search for
    
    Returns:
    
    instance of the specified annotation type if it is present on this element or null if it is not
  - getAnnotations
```
java.lang.annotation.Annotation[] getAnnotations()
```
    Returns all the annotations present on this element. For a class, the list will include annotations on supertypes as well.
  - getDeclaredAnnotations
```
java.lang.annotation.Annotation[] getDeclaredAnnotations()
```
    Returns the annotations declared directly on this element; does not include any inherited annotations.
  - isAnnotationPresent
```
boolean isAnnotationPresent(java.lang.Class<? extends java.lang.annotation.Annotation> annotationClass)
```
    Returns true if this item has an annotation of the specified type. For a class, this will look at supertypes as well.
    
    Returns:
    
    true if this item has an annotation of the specified type
