Member Function Documentation

OptionSelection * OptionSelection::add ( Option * o) [virtual]

void OptionSelection::delete_values () [virtual]

Reimplemented from Option.

bool OptionSelection::parse ( TokenStream * tokens,
bool & changed,
ValueClass * parent) [virtual]

returns true if the token stream parsing does not fail at this option.

sets the changed parameter to true if the option parsing generated some state. The changed token is important in loops because OptionSelections can succeed without actually consuming any of the token stream.

Reimplemented from Option.

void OptionSelection::print ( String & command_line_string,
suif_vector<OptionDescription>* descriptions) const [virtual]

Prepare the printable description of this option.

Append a printed message to command_line_string, and a description to descriptions.

Reimplemented from Option.
