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 ret = '';
  ret +=
      'Eventlistener "$_id" has received $numberReceivedMessages messages\n';
  ret += 'Eventlistener "$_id" has handled $numberHandledMessages messages\n';
  ret +=
      'Eventlistener "$_id" has dropped ${numberReceivedMessages - numberHandledMessages} messages\n';
  return ret;
}
