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 result = StringBuffer();
  for (int i = 0; i < length; i++) {
    if (i > 0) {
      result.write(', ');
    }
    if (isECI(i)) {
      result.write('ECI(');
      result.write(getECIValue(i));
      result.write(')');
    } else if (charAt(i) < 128) {
      result.write('\'');
      result.writeCharCode(charAt(i));
      result.write('\'');
    } else {
      result.write(charAt(i));
    }
  }
  return result.toString();
}
