示例1: readEfpParamsSection
void QChemInput::readEfpParamsSection(TextStream& textStream)
{
EfpFragment parser;
while (!textStream.atEnd()) {
parser.loadNextFragment(textStream);
if (textStream.previousLine().contains("$end", Qt::CaseInsensitive)) break;
}
}示例2: loadNextFragment
QString EfpFragment::loadNextFragment(TextStream& textStream)
{
QString line(textStream.previousLine());
if (!line.contains("fragment", Qt::CaseInsensitive)) {
line = textStream.seek("fragment", Qt::CaseInsensitive);
}
QStringList tokens(TextStream::tokenize(line));
QString name;
if (tokens.size() >= 2 && tokens[0].toLower() == "fragment") {
name = tokens[1];
}else {
return QString();
}
CartesianCoordinates parser;
Data::Geometry* geom(parser.parse(textStream));
if ( !geom || !parser.error().isEmpty()) {

delete geom;
return QString();
}
if (name.endsWith("_L", Qt::CaseInsensitive)) {
Data::EfpFragmentLibrary::instance().add(name, geom);
}else {
// We assume the fragment is not in the library and so we need to collect
// the additional guff so we can add it to the input file if required.
QString line;
