Constructor & Destructor Documentation

GClasses::GArgReader::GArgReader	(	int	argc,
		char *	argv[]
	)

Pass the args that are passed in to main.

GClasses::GArgReader::GArgReader ( GArgReader & other )

copy constructor

void GClasses::GArgReader::clear_args ( )

Clears the args.

int GClasses::GArgReader::get_argc ( )

inline

Returns the value of argc.

int GClasses::GArgReader::get_pos ( )

Returns the current position–that is, the argument number.

bool GClasses::GArgReader::if_pop ( const char * flagName )

If the current arg matches flagName, advances and returns true. Otherwise, returns false (without advancing).

bool GClasses::GArgReader::next_is_flag ( )

Returns true if there is another arg, and it begins with '-'.

bool GClasses::GArgReader::next_is_uint ( )

Returns true if there is another arg, and it would parse accurately as an unsigned integer.

const char* GClasses::GArgReader::peek ( )

Returns the current arg (without advancing)

double GClasses::GArgReader::pop_double ( )

Returns the current arg as a double, and advances. Throws an exception if the end of the args was already reached before this call.

const char* GClasses::GArgReader::pop_string ( )

Returns the current arg as a string, and advances. Throws an exception if the end of the args was already reached before this call.

unsigned int GClasses::GArgReader::pop_uint ( )

Returns the current arg as a uint, and advances. Throws an exception if the end of the args was already reached before this call.

void GClasses::GArgReader::set_argc ( int argc )

inline

Returns the value of argc.

void GClasses::GArgReader::set_pos ( int n )

Sets the current position.

int GClasses::GArgReader::size ( )

Returns the number of remaining args.
