Constructor Detail

BinaryExpression

public BinaryExpression(Expression<? extends O1> firstOperand,
                        Expression<? extends O2> secondOperand,
                        java.util.function.BiFunction<? super O1,? super O2,? extends R> operation)

Parameters:

firstOperand - An expression providing the first operand for the function.

secondOperand - An expression providing the second operand for the function.

operation - A function transforming the operands into a value of this expression's type.
