Method Detail

isAnnotationPresent

boolean isAnnotationPresent(Class<? extends Annotation> annotationClass)

Returns true if an annotation for the specified type is present on this element, else false. This method is designed primarily for convenient access to marker annotations.

Parameters:

annotationClass - the Class object corresponding to the annotation type

Returns:

true if an annotation for the specified annotation type is present on this element, else false

Throws:

NullPointerException - if the given annotation class is null

Since:

1.5

getAnnotation

IAnnotationInfo getAnnotation(Class<? extends Annotation> annotationClass)

Returns this element's annotation for the specified type if such an annotation is present, else null.

Parameters:

annotationClass - the Class object corresponding to the annotation type

Returns:

this element's annotation for the specified annotation type if present on this element, else null

Throws:

NullPointerException - if the given annotation class is null

Since:

1.5

getDeclaredAnnotations

IAnnotationInfo[] getDeclaredAnnotations()

Returns all annotations that are directly present on this element. Unlike the other methods in this interface, this method ignores inherited annotations. (Returns an array of length zero if no annotations are directly present on this element.) The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.

Returns:

All annotations directly present on this element

Since:

1.5

getEnclosingClass

IJavaClassInfo getEnclosingClass()
