Method Detail
-
apply
int apply(int x)
Computes the operator on the given input.- Parameters:
x
- the input.- Returns:
- the output of the operator on the given input.
-
identity
static IntUnaryOperator identity()
Returns aUnaryOperator
that always returns the input unmodified.- See Also:
UnaryOperator.identity()
-
negation
static IntUnaryOperator negation()
Returns aUnaryOperator
that always returns the arithmetic negation of the input.- Implementation Notes:
- As with all negation, be wary of unexpected behavior near the minimum value of the data type.
For example, -
Integer.MIN_VALUE
will result inInteger.MIN_VALUE
(still negative), as the positive value ofInteger.MIN_VALUE
is too big forint
(it would be 1 greater thenInteger.MAX_VALUE
).
