public interface AnnotationProvider

An implementation of AnnotationProvider returns annotations on Java AST elements.

Method Summary

Modifier and Type	Method and Description
javax.lang.model.element.AnnotationMirror	getAnnotationMirror(com.sun.source.tree.Tree tree, java.lang.Class<? extends java.lang.annotation.Annotation> target) Return the annotation on tree that is in the hierarchy that contains the qualifier target.
javax.lang.model.element.AnnotationMirror	getDeclAnnotation(javax.lang.model.element.Element elt, java.lang.Class<? extends java.lang.annotation.Annotation> anno) Returns the AnnotationMirror, of the given class or an alias of it, used to annotate the element.

Method Detail

getDeclAnnotation

javax.lang.model.element.AnnotationMirror getDeclAnnotation(javax.lang.model.element.Element elt,
                                                            java.lang.Class<? extends java.lang.annotation.Annotation> anno)

Returns the AnnotationMirror, of the given class or an alias of it, used to annotate the element. Returns null if no annotation equivalent to anno exists on elt.

Parameters:

elt - the element

anno - annotation class

Returns:

an annotation mirror of class anno on elt, or an equivalent one, or null if none exists on anno

getAnnotationMirror

javax.lang.model.element.AnnotationMirror getAnnotationMirror(com.sun.source.tree.Tree tree,
                                                              java.lang.Class<? extends java.lang.annotation.Annotation> target)

Return the annotation on tree that is in the hierarchy that contains the qualifier target. Returns null if none exists.

Parameters:

tree - the tree of which the annotation is returned

target - the class of the annotation

Returns:

the annotation on tree that has the class target, or null
