Interface DoubleBinarySQLOperator

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 DoubleBinarySQLOperator

Represents an operation upon two double-valued operands and producing a double-valued result. This is the SQLException 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 DoubleBinarySQLOperator	checked(DoubleBinaryOperator operator) Returns a binary operator that applies the operator operator to its input, and unwraps any UncheckedSQLException that is thrown by throwing its cause.
static DoubleBinaryOperator	unchecked(DoubleBinarySQLOperator operator) Returns a binary operator that applies the operator operator to its input, and wraps any SQLException that is thrown in an UncheckedSQLException.

Method Detail

applyAsDouble

double applyAsDouble(double left,
                     double right)
              throws SQLException

Applies this operator to the given operands.

Parameters:

left - The first operand.

right - The second operand.

Returns:

The operator result.

Throws:

SQLException - If an SQL error occurs.

unchecked

static DoubleBinaryOperator unchecked(DoubleBinarySQLOperator operator)

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

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 SQLException that is thrown in an UncheckedSQLException.

Throws:

NullPointerException - If operator is null.

checked

static DoubleBinarySQLOperator checked(DoubleBinaryOperator operator)

Returns a binary operator that applies the operator operator to its input, and unwraps any UncheckedSQLException 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 UncheckedSQLException that is thrown.

Throws:

NullPointerException - If operator is null.
