public interface Annotation
AnnotatedElement
interface discusses
compatibility concerns when evolving an annotation type from being
non-repeatable to being repeatable.Modifier and Type | Method | Description |
---|---|---|
Class<? extends Annotation> |
annotationType() |
Returns the annotation type of this annotation.
|
boolean |
equals(Object obj) |
Returns true if the specified object represents an annotation
that is logically equivalent to this one.
|
int |
hashCode() |
Returns the hash code of this annotation, as defined below:
|
String |
toString() |
Returns a string representation of this annotation.
|
boolean equals(Object obj)
x
and y
are considered equal if x == y
,
unless their type is float
or double
.
float
members whose values
are x
and y
are considered equal if
Float.valueOf(x).equals(Float.valueOf(y))
.
(Unlike the ==
operator, NaN is considered equal
to itself, and 0.0f
unequal to -0.0f
.)
double
members whose values
are x
and y
are considered equal if
Double.valueOf(x).equals(Double.valueOf(y))
.
(Unlike the ==
operator, NaN is considered equal
to itself, and 0.0
unequal to -0.0
.)
String
, Class
, enum, or
annotation typed members whose values are x
and y
are considered equal if x.equals(y)
. (Note that this
definition is recursive for annotation typed members.)
x
and y
are considered equal if Arrays.equals(x, y)
, for the
appropriate overloading of Arrays.equals(long[], long[])
.
equals
in class Object
obj
- the reference object with which to compare.Object.hashCode()

HashMap
int hashCode()
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 String.hashCode()
) XOR
the hash code of the member-value, as defined below:
The hash code of a member-value depends on its type:
v
is equal to
WrapperType.valueOf(v).hashCode()
, where
WrapperType
is the wrapper type corresponding
to the primitive type of v
(Byte
,
Character
, Double
, Float
, Integer
,
Long
, Short
, or Boolean
).
v
is computed as by calling
v.hashCode()
. (In the case of annotation
member values, this is a recursive definition.)
Arrays.hashCode
on the value. (There is one overloading for each primitive
type, and one for object reference types.)
