Annotation Type Constant

@Documented
 @Retention(value=RUNTIME)
 @Target(value={TYPE_USE,TYPE_PARAMETER})
 @SubtypeOf(value={Unsigned.class,Signed.class})
public @interface Constant

The value may be interpreted as Signed or Unsigned. It is either a manifest literal, or it is a value whose most significant bit is not set (so it has the same interpretation as signed or unsigned)

The programmer should not write this annotation; the programmer should always write Signed or Unsigned to indicate how the value is intended to be interpreted. The programmer can also annotate values as @NonNegative, @Positive, or @IntRange(from=someNonNegativeConstant).
