Detailed Description

A simple switch argument.

If the switch is set on the command line, then the getValue method will return the opposite of the default value for the switch.

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.

	)		`[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.
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.

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().
