The common interface extended by all annotation types. Note that an interface that manually extends this one does not define an annotation type. Also note that this interface does not itself define an annotation type. More information about annotation types can be found in section 9.6 of The Java™ Language Specification.

Class<? extends Annotation>
|
annotationType()
Returns the annotation type of this annotation. |
abstract
boolean

equals(Object obj)
Returns true if the specified object represents an annotation that is logically equivalent to this one. |
abstract
int
|
hashCode()
Returns the hash code of this annotation, as defined below: The hash code of an annotation is the sum of the hash codes
of its members (including those with default values), as defined
below:
The hash code of an annotation member is (127 times the hash code
of the member-name as computed by The hash code of a member-value depends on its type: |

toString()
Returns a string representation of this annotation. |
Class<? extends Annotation> annotationType ()
Returns the annotation type of this annotation.

Class<? extends Annotation> |
boolean equals (Object obj)
Returns true if the specified object represents an annotation that is logically equivalent to this one. In other words, returns true if the specified object is an instance of the same annotation type as this instance, all of whose members are equal to the corresponding member of this annotation, as defined below:
equals(boolean[], boolean[])
.
Parameters | |
---|---|
obj |
Object :
the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if the specified object represents an annotation that is logically equivalent to this one, otherwise false |
int hashCode ()
Returns the hash code of this annotation, as defined below:
The hash code of an annotation is the sum of the hash codes
of its members (including those with default values), as defined
below:
The hash code of an annotation member is (127 times the hash code
of the member-name as computed by hashCode()
) XOR
the hash code of the member-value, as defined below:
The hash code of a member-value depends on its type:
Byte
,
Character
, Double
, Float
, Integer
,
Long
, Short
, or Boolean
).
Arrays.hashCode
on the value. (There is one overloading for each primitive
type, and one for object reference types.)

String toString ()
Returns a string representation of this annotation. The details of the representation are implementation-dependent, but the following may be regarded as typical:
@com.acme.util.Name(first=Alfred, middle=E., last=Neuman)
