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() {
  final buf = StringBuffer();
  buf.write('$stateNumber:$configs');
  if (isAcceptState) {
    buf.write('=>');
    if (predicates != null) {
      buf.write(arrayToString(predicates));
    } else {
      buf.write(prediction);
    }
  }
  return buf.toString();
}
