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() {
  StringBuffer sb = StringBuffer('\nBook:\n');
  sb.writeln('  title:$title');
  sb.writeln('  full_title:$full_title');
  sb.writeln('  subtitle:$subtitle');

  sb.write('  authors:[');
  for (int i = 0; i < authors.length; i++) {
    sb.write('${authors[i]}${i < authors.length - 1 ? ',' : ''}');
  }
  sb.writeln(']');
  sb.writeln(
      '  number_of_pages:${number_of_pages > 0 ? number_of_pages : ''}');
  sb.writeln('  subjects:$subjects');
  sb.writeln('  contributions:$contributions');
  sb.writeln('  isbn_10:$isbn_10');
  sb.writeln('  isbn_13:$isbn_13');
  sb.writeln('  ia_box_id:$ia_box_id');
  sb.writeln('  ocaid:$ocaid');
  sb.writeln('  publishers:$publishers');
  sb.writeln('  publish_places:$publish_places');
  sb.writeln('  publish_date:$publish_date');
  sb.writeln('  physical_format:$physical_format');
  sb.writeln('  physical_dimensions:$physical_dimensions');
  sb.writeln('  weight:$weight');
  sb.writeln('  revision:${revision > 0 ? revision : ""}');
  sb.writeln(
      '  latest_revision:${latest_revision > 0 ? latest_revision : ""}');
  sb.writeln('  covers:${covers.length}');
  sb.writeln('  pagination:$pagination');
  sb.writeln('  lc_classifications:$lc_classifications');
  return sb.toString();
