Detailed Description

It only makes sense to have a single one of these set and it is also exclusive with CommandOptionRest.

This makes parameter collecting behave line the Unix "cat" command.

CommandOption to collect parameters that are not options.

Member Enumeration Documentation

enum CommandOption::OptionType

inherited

OptionType is for denoting what type of option this is, with an arg, without an arg or the trailing args.

Option type

Enumerator
hasArg	This option is associated with a value.
noArg	This option is a flag only.
trailing	Remaining of the command line arguments.
collect	Collect values that are not a value to an option.

Definition at line 103 of file cmdoptns.h.

Constructor & Destructor Documentation

CommandOptionCollect::CommandOptionCollect	(	const char *	inOptionName,
		const char *	inOptionLetter,
		const char *	inDescription,
		bool	inRequired = `false`,
		CommandOption **	ppNext = `&defaultCommandOptionList`
	)

CommandOptionRest contructor.

This sets the optionType for this object to Collect.

Parameters

inOptionName	long option name
inOptionLetter	short letter name
inDescription	short description of the option
inRequired	true if option is required
ppNext	the linked list header

Member Function Documentation

virtual void CommandOptionWithArg::foundOption	(	CommandOptionParse *	cop,
		const char *	value = `0`
	)

virtualinherited

foundOption is called by the CommandOptionParse object during the parsing of the command line options.

Parameters

cop	pointer to the command option parser
value	the value of this option

Reimplemented from CommandOption.

virtual void CommandOptionWithArg::foundOption	(	CommandOptionParse *	cop,
		const char **	value,
		int	num
	)

virtualinherited

foundOption is called by the CommandOptionParse object during the parsing of the command line options.

Parameters

cop	pointer to the command option parser
value	an array of values of this option
num	number of values in the array

Reimplemented from CommandOption.

virtual bool CommandOptionWithArg::hasValue ( )

virtualinherited

For fields with the required flag set, this method is used to determine if the Option has satisfied it's required status.

The default methods simply returns true if any values have been found. This could be specialized to return true based on some other criteria.

Reimplemented from CommandOption.

virtual void CommandOption::parseDone ( CommandOptionParse * cop )

virtualinherited

Once parsing of command line options is complete, this method is called.

This can be used to perform last minute checks on the options collected.

Parameters

cop	pointer to the command option parser

virtual void CommandOption::performTask ( CommandOptionParse * cop )

virtualinherited

Once CommandOption objects have completed parsing and there are no errors they may have some specific tasks to perform.

PerformTask must return.

Parameters

cop	pointer to the command option parser

Field Documentation

const char* CommandOption::description

inherited

A short description of the option for Usage messages.

e.g. Usage: mycommand : blah -f, –file <DESCRIPTION here>

Definition at line 96 of file cmdoptns.h.

CommandOption* CommandOption::next

inherited

This next CommandOption in this list of options or nil if no more options exist.

Definition at line 137 of file cmdoptns.h.

int CommandOptionWithArg::numValue

inherited

Number of values in the values array.

Definition at line 225 of file cmdoptns.h.

const char* CommandOption::optionLetter

inherited

option letter, these will be preceded with "-" on the command line.

e.g. -f foo.x

Definition at line 89 of file cmdoptns.h.

const char* CommandOption::optionName

inherited

Long option name, these will be preceded with "--" on the command line.

e.g. –file foo.x

Definition at line 83 of file cmdoptns.h.

OptionType CommandOption::optionType

inherited

This command option's OptionType.

Definition at line 125 of file cmdoptns.h.

bool CommandOption::required

inherited

True if this parameter is required.

If the parameter is not supplied and required is true, an error will be flagged in the option processor.

Definition at line 131 of file cmdoptns.h.

const char** CommandOptionWithArg::values

inherited

Array of list of values collected for this option.

Definition at line 220 of file cmdoptns.h.
