Definition at line 370 of file RelationsObject.h.

    {
      return _RelationsInterfaceImpl::htmlToPlainText(getInfoHTML());
    }

◆ getInfoHTML()

virtual std::string getInfoHTML ( ) const

inlinevirtualinherited

Return a short summary of this object's contents in HTML format.

Reimplement this in your own class to provide useful output for display or debugging purposes. For example, you might do something like:

std::stringstream out;
out << "<b>PDG</b>: " << m_pdg << "<br>";
out << "<b>Covariance Matrix</b>: " << HTML::getString(getCovariance5()) << "<br>";
return out.str();

See also: Particle::getInfoHTML() for a more complex example.; HTML for some utility functions.; Use getInfo() to get a raw text version of this output.
