Detailed Description

An OptionInt matches an integer in the command line.

Constructor & Destructor Documentation

OptionInt::OptionInt ( String arguments = String("int"),
int * storage_for_integer = 0)

Construct with a name for this option and a location to hold an int.

OptionInt::~OptionInt () [virtual]

Member Function Documentation

IntValueClass * OptionInt::get_int ( ValueClass * value,
Option * context) const [virtual]

IntValueClass * OptionInt::get_int ( int number = 0) [virtual]

bool OptionInt::parse ( TokenStream * tokens,
bool & changed,
ValueClass * parent = 0) [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.
