toString method

@override String toString([ String prefix = '' ])

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([String prefix = '']) {
  var buffer = StringBuffer();
  String piString;
  try {
    piString = policyIdentifier.toString();
  } catch (e) {
    if (e is UnknownOIDNameError) {
      // It is unique definition policy. should not convert name.
      // In this case, to be just combined numbers.
      piString = policyIdentifier.nodes.map((i) => i.toString()).join('.');
    } else {
      rethrow;
    }
  }
  buffer.writeln('${prefix}Policy: $piString');
  buffer.writeln(
      policyQualifiers.map((q) => q.toString('$prefix\t')).join('\n'));
  return buffer.toString();
}
