IntUnaryOperator
public
interface
IntUnaryOperator
| java.util.function.IntUnaryOperator
|
Represents an operation on a single int-valued operand that produces
an int-valued result. This is the primitive type specialization of
UnaryOperator for int.
This is a functional interface
whose functional method is applyAsInt(int).
Summary
Public methods |
|---|
default
IntUnaryOperator
|
andThen(IntUnaryOperator after)
Returns a composed operator that first applies this operator to
its input, and then applies the after operator to the result.
|
abstract
int
|
applyAsInt(int operand)
Applies this operator to the given operand.
|
default
IntUnaryOperator
|
compose(IntUnaryOperator before)
Returns a composed operator that first applies the before
operator to its input, and then applies this operator to the result.
|
static
IntUnaryOperator
|
identity()
Returns a unary operator that always returns its input argument.
|
Public methods
andThen
public IntUnaryOperator andThen (IntUnaryOperator after)
Returns a composed operator that first applies this operator to
its input, and then applies the after operator to the result.
If evaluation of either operator throws an exception, it is relayed to
the caller of the composed operator.
| Parameters |
|---|
after |
IntUnaryOperator: the operator to apply after this operator is applied |
| Returns |
|---|
IntUnaryOperator |
a composed operator that first applies this operator and then
applies the after operator |
applyAsInt
public abstract int applyAsInt (int operand)
Applies this operator to the given operand.
| Parameters |
|---|
operand |
int: the operand |
| Returns |
|---|
int |
the operator result |
compose
public IntUnaryOperator compose (IntUnaryOperator before)
Returns a composed operator that first applies the before
operator to its input, and then applies this operator to the result.
If evaluation of either operator throws an exception, it is relayed to
the caller of the composed operator.
| Parameters |
|---|
before |
IntUnaryOperator: the operator to apply before this operator is applied |
| Returns |
|---|
IntUnaryOperator |
a composed operator that first applies the before
operator and then applies this operator |
identity
public static IntUnaryOperator identity ()
Returns a unary operator that always returns its input argument.
| Returns |
|---|
IntUnaryOperator |
a unary operator that always returns its input argument |
