Constructor & Destructor Documentation

TCLAP::SwitchArg::SwitchArg	(	const std::string &	flag,
		const std::string &	name,
		const std::string &	desc,
		bool	def = false,
		Visitor *	v = NULL
	)		[inline]

SwitchArg constructor.

Parameters:

flag	- The one character flag that identifies this argument on the command line.
name	- A one word name for the argument. Can be used as a long flag on the command line.
desc	- A description of what the argument is for or does.
def	- The default value for this Switch.
v	- An optional visitor. You probably should not use this unless you have a very good reason.

Definition at line 124 of file SwitchArg.h.

SwitchArg constructor.

Parameters:

flag	- The one character flag that identifies this argument on the command line.
name	- A one word name for the argument. Can be used as a long flag on the command line.
desc	- A description of what the argument is for or does.
parser	- A CmdLine parser object to add this Arg to
def	- The default value for this Switch.
v	- An optional visitor. You probably should not use this unless you have a very good reason.

[inline]

Returns bool, whether or not the switch has been set.

Here is the caller graph for this function:

bool TCLAP::SwitchArg::processArg	(	int *	i,
		std::vector< std::string > &	args
	)		[inline, virtual]

Handles the processing of the argument. This re-implements the Arg version of this method to set the _value of the argument appropriately.

Parameters:

i	- Pointer the the current argument in the list.
args	- Mutable list of strings. Passed in from main().

Implements TCLAP::Arg.

void TCLAP::SwitchArg::reset

(

)

[inline, virtual]

Clears the Arg object and allows it to be reused by new command lines.
