Detailed Description

template<class T>
class ecl::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.

Definition at line 36 of file multi_arg.hpp.

Constructor & Destructor Documentation

template<class T >

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

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.

Member Function Documentation

template<class T >

void ecl::MultiArg< T >::_extractValue ( const std::string & val )

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 487 of file multi_arg.hpp.

template<class T >

bool ecl::MultiArg< T >::allowMore ( )

virtual

Reimplemented from ecl::Arg.

Definition at line 510 of file multi_arg.hpp.

template<class T >

const std::vector< T > & ecl::MultiArg< T >::getValue ( )

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

Definition at line 392 of file multi_arg.hpp.

template<class T >

bool ecl::MultiArg< T >::isRequired ( ) const

virtual

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

Reimplemented from ecl::Arg.

Definition at line 472 of file multi_arg.hpp.

template<class T >

std::string ecl::MultiArg< T >::longID ( const std::string & val = "val" ) const

virtual

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

Parameters

val	- value to be used.

Reimplemented from ecl::Arg.

Reimplemented in ecl::UnlabeledMultiArg< T >.

Definition at line 460 of file multi_arg.hpp.

template<class T >

bool ecl::MultiArg< T >::processArg	(	int *	i,
		std::vector< std::string > &	args
	)

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 ecl::Arg.

Reimplemented in ecl::UnlabeledMultiArg< T >.

Definition at line 395 of file multi_arg.hpp.

template<class T >

std::string ecl::MultiArg< T >::shortID ( const std::string & val = "val" ) const

virtual

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

Parameters

val	- value to be used.

Reimplemented from ecl::Arg.

Reimplemented in ecl::UnlabeledMultiArg< T >.

Definition at line 449 of file multi_arg.hpp.
