operator == method

  1. @override
bool operator ==(
  1. Object other
)

The equality operator.

The default behavior for all Objects is to return true if and only if this object and other are the same object.

Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:

  • Total: It must return a boolean for all arguments. It should never throw.

  • Reflexive: For all objects o, o == o must be true.

  • Symmetric: For all objects o1 and o2, o1 == o2 and o2 == o1 must either both be true, or both be false.

  • Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are true, then o1 == o3 must be true.

The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.

If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.

Implementation

@override
bool operator ==(Object other) {
  if (identical(this, other)) return true;
  if (other is! LaneType) return false;
  LaneType _other = other;
  return isRegular == _other.isRegular &&
      isHighOccupancyVehicle == _other.isHighOccupancyVehicle &&
      isReversible == _other.isReversible &&
      isExpress == _other.isExpress &&
      isAcceleration == _other.isAcceleration &&
      isDeceleration == _other.isDeceleration &&
      isAuxiliary == _other.isAuxiliary &&
      isSlow == _other.isSlow &&
      isPassing == _other.isPassing &&
      isShoulder == _other.isShoulder &&
      isRegulatedAccess == _other.isRegulatedAccess &&
      isTurn == _other.isTurn &&
      isCenterTurn == _other.isCenterTurn &&
      isTruckParking == _other.isTruckParking &&
      isParking == _other.isParking &&
      isVariableDriving == _other.isVariableDriving &&
      isBicycle == _other.isBicycle;
