Constructor Details

#initialize(left_operand = nil, right_operand = nil, binary_operator_type = BinaryOperatorType::EQUAL) ⇒ Void

The constructor for this operator. Expects the operands and the operator type as parameters.

Parameters:

  • left_operand (BaseOperator) (defaults to: nil) —

    the left hand side operand

  • right_operand (BaseOperator) (defaults to: nil) —

    the right hand side operand

  • binary_operator_type (BinaryOperatorType) (defaults to: BinaryOperatorType::EQUAL) —

    the type of this operator
