Detailed Description

template<class T>
class TCLAP::MultiArg< T >

An argument that allows multiple values of type T to be specified. Very similar to a ValueArg, except a vector of values will be returned instead of just one.

Constructor & Destructor Documentation

template<class T >

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

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.
	req	- Whether the argument is required 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.
	v	- An optional visitor. You probably should not use this unless you have a very good reason.

template<class T>

TCLAP::MultiArg< T >::MultiArg ( const MultiArg< T > & rhs ) [private]

Prevent accidental copying

Member Function Documentation

template<class T >

void TCLAP::MultiArg< T >::_extractValue ( const std::string & val ) [inline, protected]

Extracts the value from the string. Attempts to parse string as type T, if this fails an exception is thrown.

Parameters:

val

- The string to be read.

Definition at line 398 of file MultiArg.h.

template<class T >

bool TCLAP::MultiArg< T >::allowMore ( ) [inline, virtual]

Used for MultiArgs and XorHandler to determine whether args can still be set.

Reimplemented from TCLAP::Arg.

Definition at line 417 of file MultiArg.h.

template<class T>

const_iterator TCLAP::MultiArg< T >::begin ( ) const [inline]

Returns an iterator over the values parsed from the command line.

Definition at line 194 of file MultiArg.h.

template<class T>

const_iterator TCLAP::MultiArg< T >::end ( ) const [inline]

Returns the end of the values parsed from the command line.

Definition at line 200 of file MultiArg.h.

template<class T >

const std::vector< T > & TCLAP::MultiArg< T >::getValue ( ) [inline]

Returns a vector of type T containing the values parsed from the command line.

Definition at line 305 of file MultiArg.h.

template<class T >

bool TCLAP::MultiArg< T >::isRequired ( ) const [inline, virtual]

Once we've matched the first value, then the arg is no longer required.

Reimplemented from TCLAP::Arg.

Definition at line 383 of file MultiArg.h.

template<class T >

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

Returns the a long id string. Used in the usage.

Parameters:

val

- value to be used.

MultiArg<T>& TCLAP::MultiArg< T >::operator= ( const MultiArg< T > & rhs ) [private]

template<class T >

bool TCLAP::MultiArg< 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. It knows the difference between labeled and unlabeled.

Parameters:

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

Implements TCLAP::Arg.

Reimplemented in TCLAP::UnlabeledMultiArg< T >.

Parameters:

val

- value to be used.
