Interface LongBinaryIOOperator

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 LongBinaryIOOperator

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

Method Summary

Modifier and Type	Method and Description
long	applyAsLong(long left, long right) Applies this operator to the given operands.
static LongBinaryIOOperator	checked(LongBinaryOperator 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 LongBinaryOperator	unchecked(LongBinaryIOOperator 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

applyAsLong

long applyAsLong(long left,
                 long 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 LongBinaryOperator unchecked(LongBinaryIOOperator 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 LongBinaryIOOperator checked(LongBinaryOperator 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.
