Interface DoubleBinaryIOOperator

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 DoubleBinaryIOOperator

Represents an operation upon two double-valued operands and producing a double-valued result. This is the IOException throwing equivalent of DoubleBinaryOperator.

Method Summary

Modifier and Type	Method and Description
double	applyAsDouble(double left, double right) Applies this operator to the given operands.
static DoubleBinaryIOOperator	checked(DoubleBinaryOperator operator) Returns a binary operator that applies the operator operator to its input, and unwraps any UncheckedIOException that is thrown by throwing its cause.
static DoubleBinaryOperator	unchecked(DoubleBinaryIOOperator operator) Returns a binary operator that applies the operator operator to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Method Detail

applyAsDouble

double applyAsDouble(double left,
                     double right)
              throws IOException

Applies this operator to the given operands.

Parameters:

left - The first operand.

right - The second operand.

Returns:

The operator result.

Throws:

IOException - If an I/O error occurs.

unchecked

static DoubleBinaryOperator unchecked(DoubleBinaryIOOperator operator)

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

Parameters:

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

Returns:

A binary 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 DoubleBinaryIOOperator checked(DoubleBinaryOperator operator)

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

Parameters:

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

Returns:

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

Throws:

NullPointerException - If operator is null.
