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()

getLocationInfo
default ILocationInfo getLocationInfo()
