Detailed Description

An OptionLoop represents a Kleene closure; i.e.

a repeated application of a sub-option.

Constructor & Destructor Documentation

OptionLoop::OptionLoop ( Option * loop_contents,
bool allow_empty = true)

OptionLoop::~OptionLoop () [virtual]

Member Function Documentation

void OptionLoop::delete_values () [virtual]

Reimplemented from Option.

bool OptionLoop::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 OptionLoop::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.
