The
constants
declared by this enumerated type represent the types of program
elements that can be annotated. The value of an
@Target annotation is an array of
ElementType constants. Most of the
constants
have obvious meanings, but some require additional explanation.
TYPE represents a class, interface, enumerated
type, or annotation type. ANNOTATION_TYPE
represents only annotation types and is used for meta-annotations.
FIELD includes enumerated constants, and
PARAMETER includes both method parameters and
catch clause parameters. Note that the
METHOD and CONSTRUCTOR are
distinct constants.
