toString method

@override String toString([ Vocabulary? vocabulary ])

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([Vocabulary? vocabulary]) {
  vocabulary = vocabulary ?? VocabularyImpl.EMPTY_VOCABULARY;
  if (s0 == null) {
    return '';
  }

  final serializer = DFASerializer(this, vocabulary);
  return serializer.toString();
}
