CLASS ARG.Int EXTENDS ARG.Flag @public

summary

A Flag that has one number argument.

For example, with this flag:

 ARG.Int retry = NEW("r", "retry", 3, "retry count")

These arguments can be used:

 prog --retry 20
 prog --retry=8
 prog -r 4
 prog -r1

By default the flag is not allowed to be used more than once. Use enableRepeat() to allow it.

	NEW(shortName, longName, default, doc) @public	Create an Int Flag.
	$enableRepeat() ARG.Int @public	Allow the flag to appear more than once.
	$get() int @public	Return the value.
	$value() int @public	Return the value.
	$getList() list<int> @file	Return the list of values.
	$valueList() list<int> @file	Return the list of values.

Inherited from ARG.Flag:
	$setArgName(argName) ARG.Flag @public	Set the text used in the --help output for the argument.
	$disableCompact() ARG.Flag @public	Disable the compact form of flag values.
	$optionalArg() ARG.Flag @public	Make the flag argument optional.
	$presentCount() int @public	Return the number of times the command line flag was encountered.
	$present() bool @public	Return TRUE if the command line flag was encountered.

PROC NEW(string shortName, string longName, int default, string doc) @public

Create an Int Flag.

shortName is the one-character name, can be NIL. longName is the longer name, to be used after "--", can be NIL shortName and longName can't both be NIL. default is the default value, used when the flag is not present. doc is displayed for this flag with the --help argument.

FUNC $enableRepeat() ARG.Int @public

Allow the flag to appear more than once.

Returns THIS, so that it can be used in a declaration like this:

 ARG.String name = NEW("n", "name", "", "the name").enableRepeat()

The value of the last flag will then be stored and can be obtained with get() and value(), getList() and valueList() return a list with all the values and presentCount() returns the number of times the flag appears.

This must be invoked in EarlyInit() or earlier.

FUNC $get() int @public

Return the value.

When the flag was not encountered it will be the specified default.

Can only be used after EarlyInit(), when ARG.Ready is TRUE.

FUNC $getList() list<int> @file

Return the list of values.

When the flag was not encountered it will be an empty list Otherwise the list contains all the values encountered. When a flag doesn't have a value, the default value is used.

Can only be used after EarlyInit(), when ARG.Ready is TRUE.

FUNC $value() int @public

Return the value.

When the flag was not encountered it will be the specified default.

Can only be used after EarlyInit(), when ARG.Ready is TRUE.

FUNC $valueList() list<int> @file

Return the list of values.

When the flag was not encountered it will be an empty list Otherwise the list contains all the values encountered. When a flag doesn't have a value, the default value is used.

Can only be used after EarlyInit(), when ARG.Ready is TRUE.
