Constructor & Destructor Documentation

option::Parser::StoreOptionAction::StoreOptionAction	(	Parser &	parser_,
		Option	options_[],
		Option	buffer_[],
		int	bufmax_
	)

inline

Number of slots in buffer. -1 means "large enough".

Creates a new StoreOption action.

Parameters

parser_	the parser whose op_count should be updated.
options_	each Option `o` is chained into the linked list `options_`[o.desc->index]
buffer_	each Option is appended to this array as long as there's a free slot.
bufmax_	number of slots in `buffer_`. `-1` means "large enough".

find first empty slot in buffer (if any)

set parser's optionCount

Member Function Documentation

bool option::Parser::StoreOptionAction::finished	(	int	numargs,
		const char **	args
	)

inlinevirtual

Called by Parser::workhorse() after finishing the parse.

Parameters

numargs	the number of non-option arguments remaining
args	pointer to the first remaining non-option argument (if numargs > 0).

Returns: false iff a fatal error has occurred.

only overwrite non-option argument list if there's at least 1 new non-option argument. Otherwise we keep the old list. This makes it easy to use default non-option arguments.

bool option::Parser::StoreOptionAction::perform ( Option & )

inlinevirtual

Called by Parser::workhorse() for each Option that has been successfully parsed (including unknown options if they have a Descriptor whose Descriptor::check_arg does not return ARG_ILLEGAL.

Returns false iff a fatal error has occured and the parse should be aborted.
