Constructor Detail

TrinaryExpression

public TrinaryExpression(Expression<? extends O1> firstOperand,
                         Expression<? extends O2> secondOperand,
                         Expression<? extends O3> thirdOperand,
                         TriFunction<? super O1,? super O2,? super O3,? extends R> operation)

Parameters:

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

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

thirdOperand - An expression providing the third operand for the function.

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