toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  String desc;
  switch (_policy) {
    case 1:
      desc = 'CHANNEL_AUTO';
      break;
    case 2:
      desc = 'CHANNEL_HIGH_THROUGHPUT';
      break;
    case 3:
      desc = 'CHANNEL_INSTANCE';
      break;
    default:
      desc = 'POLICY_UNKNOWN';
      break;
  }
  return desc;
}
