tryParseHeaderLine method

bool tryParseHeaderLine(String line)

Try and parse the given line as one of the recognized lines in the header of a non-symbolic stack trace.

Returns whether the line was recognized and parsed successfully.

Implementation

bool tryParseHeaderLine(String line) {
  if (line.contains(_headerStartLine)) {
    // This is the start of a new non-symbolic stack trace, so reset all the
    // stored information to be parsed anew.

    _compressed = match[3]! == "yes";

    // The architecture line always proceeds the instructions section line,
    // so reset these to null just in case we missed the header line.
