Interface IntUnaryIOOperator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface IntUnaryIOOperator

Represents an operation on a single int-valued operand that produces an int-valued result. This is the IOException throwing equivalent of IntUnaryOperator.

Method Summary

Modifier and Type	Method and Description
default IntUnaryIOOperator	andThen(IntUnaryIOOperator after) Returns a composed operator that first applies this operator to its input, and then applies the after operator to the result.
int	applyAsInt(int operand) Applies this operator to the given operand.
static IntUnaryIOOperator	checked(IntUnaryOperator operator) Returns a unary operator that applies the operator operator to its input, and unwraps any UncheckedIOException that is thrown by throwing its cause.
default IntUnaryIOOperator	compose(IntUnaryIOOperator before) Returns a composed operator that first applies the before operator to its input, and then applies this operator to the result.
static IntUnaryIOOperator	identity() Returns a unary operator that always returns its input argument.
static IntUnaryOperator	unchecked(IntUnaryIOOperator operator) Returns a unary operator that applies the operator operator to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Method Detail

applyAsInt

int applyAsInt(int operand)
        throws IOException

Applies this operator to the given operand.

Parameters:

operand - The operand.

Returns:

The operator result.

Throws:

IOException - If an I/O error occurs.

compose

default IntUnaryIOOperator compose(IntUnaryIOOperator 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 - The operator to apply before this operator is applied.

Returns:

A composed operator that first applies the before operator and then applies this operator.

Throws:

NullPointerException - If before is null.

andThen(IntUnaryIOOperator)

andThen

default IntUnaryIOOperator andThen(IntUnaryIOOperator 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 - The operator to apply after this operator is applied.

Returns:

A composed operator that first applies this operator and then applies the after operator.

Throws:

NullPointerException - If after is null.

See Also:

compose(IntUnaryIOOperator)

identity

static IntUnaryIOOperator identity()

Returns a unary operator that always returns its input argument.

Returns:

a unary operator that always returns its input argument

unchecked

static IntUnaryOperator unchecked(IntUnaryIOOperator operator)

Returns a unary operator that applies the operator operator to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Parameters:

operator - The unary operator to apply when the returned unary operator is applied.

Returns:

A unary operator that applies the operator operator to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Throws:

NullPointerException - If operator is null.

checked

static IntUnaryIOOperator checked(IntUnaryOperator operator)

Returns a unary operator that applies the operator operator to its input, and unwraps any UncheckedIOException that is thrown by throwing its cause.

Parameters:

operator - The unary operator to apply when the returned unary operator is applied.

Returns:

A unary operator that applies the operator operator to its input, and unwraps any UncheckedIOException that is thrown.

Throws:

NullPointerException - If operator is null.
