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() {
  var weightStr = (_avoid != null && _avoid == true)
      ? "avoid"
      : (_weight != null)
          ? _weight.toString()
          : null;
  return value
      .joinWithValues([weightStr], actionSeparator: paramKeyValueSeparator);
}
