Detailed Description

template<class T>
class TCLAP::UnlabeledValueArg< T >

The basic unlabeled argument that parses a value. This is a template class, which means the type T defines the type that a given object will attempt to parse when an UnlabeledValueArg is reached in the list of args that the CmdLine iterates over.

Constructor & Destructor Documentation

template<class T >

TCLAP::UnlabeledValueArg< T >::UnlabeledValueArg	(	const std::string &	name,
		const std::string &	desc,
		bool	req,
		T	val,
		const std::string &	typeDesc,
		bool	ignoreable = `false`,
		Visitor *	v = `NULL`
	)			`[inline]`

UnlabeledValueArg constructor.

Parameters:

	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.
	req	- Whether the argument is required on the command line.
	value	- The default value assigned to this argument if it is not present on the command line.
	typeDesc	- A short, human readable description of the type that this object expects. This is used in the generation of the USAGE statement. The goal is to be helpful to the end user of the program.
	ignoreable	- Allows you to specify that this argument can be ignored if the '--' flag is set. This defaults to false (cannot be ignored) and should generally stay that way unless you have some special need for certain arguments to be ignored.
	v	- Optional Vistor. You should leave this blank unless you have a very good reason.

UnlabeledValueArg constructor.

Parameters:

	name	- A one word name for the argument. Can be used as a long flag on the command line.

Member Function Documentation

template<class T >

void TCLAP::UnlabeledValueArg< T >::addToList ( std::list< Arg * > & argList ) const [inline, virtual]

Instead of pushing to the front of list, push to the back.

Parameters:

argList

- The list to add this to.

template<class T >

std::string TCLAP::UnlabeledValueArg< T >::longID ( const std::string & val = "val" ) const [inline, virtual]

Overrides longID for specific behavior.

Overriding longID for specific output.

Reimplemented from TCLAP::ValueArg< T >.

template<class T >

bool TCLAP::UnlabeledValueArg< T >::operator== ( const Arg & a ) const [inline, virtual]

Overrides operator== for specific behavior.

template<class T >

bool TCLAP::UnlabeledValueArg< T >::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. Handling specific to unlabled arguments.

Parameters:
