Detailed Description

Parses command line arguments.

The only public method parses the given list of arguments. It returns false when something failed. This may happen if the syntax of the arguments is invalid, a value is tried to be set several times or an unknown option is tried to be set.

The class assumes all options are unset or using default values only.

◆ check()

int OptionsParser::check	(	const std::string &	arg1,
		const std::string *const	arg2,
		bool &	ok,
		const bool	ignoreAppenders
	)

staticprivate

parses the previous arguments

Parameters

[in]	arg1	The first token to parse
[in]	arg2	The second token to parse, 0 if there is none
[in,out]	ok	Whether the parsing was successfull

Returns: Number of read tokens (1 or 2)

Exceptions

InvalidArgument If a performed setting of an option failed (see Option::set)

◆ checkParameter()

bool OptionsParser::checkParameter ( const std::string & arg1 )

staticprivate

Returns the whether the given token is an option.

The given token is assumed to be an option if it starts with a '-' or a '+'.

Parameters

[in] arg1 The token to check

Returns: Whether the token is an option

static

Parses the given command line arguments.

Parameters

[in]	oc	The options container to fill
[in]	args	The command line arguments

Returns: Whether the parsing was successfull

Exceptions

InvalidArgument If a performed setting of an option failed (see Option::set)

staticprivate

Extracts the parameter directly attached to an option.

Parses single tokens which contain an option and the parameter (like -c=myconfig.cfg)

Parameters

[in]	oc	The container to store the result into
[in]	arg	The token to parse

Exceptions

InvalidArgument If a performed setting of an option failed (see Option::set)
