getopt() - Method in class gnu.getopt.Getopt

This method returns a char that is the current option that has been parsed from the command line.

For communication from `getopt' to the caller.

getOptind() - Method in class gnu.getopt.Getopt

optind it the index in ARGV of the next element to be scanned.

getOptopt() - Method in class gnu.getopt.Getopt

When getopt() encounters an invalid option, it stores the value of that option in optopt which can be retrieved with this method.

getVal() - Method in class gnu.getopt.LongOpt

Returns the value of the 'val' field for this long option

gnu.getopt - package gnu.getopt

 

H

has_arg - Variable in class gnu.getopt.LongOpt

Indicates whether the option has no argument, a required argument, or an optional argument.

L

last_nonopt - Variable in class gnu.getopt.Getopt

The index of the last non-option in argv[]

long_only - Variable in class gnu.getopt.Getopt

This flag determines whether or not we are parsing only long args

long_options - Variable in class gnu.getopt.Getopt

This is an array of LongOpt objects which describ the valid long options.

longind - Variable in class gnu.getopt.Getopt

Stores the index into the long_options array of the long option found

LongOpt - Class in gnu.getopt

This object represents the definition of a long option in the Java port of GNU getopt.

LongOpt(String, int, StringBuffer, int) - Constructor for class gnu.getopt.LongOpt

Create a new LongOpt object with the given parameter values.

longopt_handled - Variable in class gnu.getopt.Getopt

A flag which communicates whether or not checkLongOption() did all necessary processing for the current option

M

main(String[]) - Static method in class GetoptDemo

 

N

name - Variable in class gnu.getopt.LongOpt

The name of the long option

nextchar - Variable in class gnu.getopt.Getopt

The next char to be scanned in the option-element in which the last option character we returned was found.

NO_ARGUMENT - Static variable in class gnu.getopt.LongOpt

Constant value used for the "has_arg" constructor argument.

O

optarg - Variable in class gnu.getopt.Getopt

For communication from `getopt' to the caller.

opterr - Variable in class gnu.getopt.Getopt

Callers store false here to inhibit the error message for unrecognized options.

optind - Variable in class gnu.getopt.Getopt

Index in ARGV of the next element to be scanned.

OPTIONAL_ARGUMENT - Static variable in class gnu.getopt.LongOpt

Constant value used for the "has_arg" constructor argument.

optopt - Variable in class gnu.getopt.Getopt

When an unrecognized option is encountered, getopt will return a '?' and store the value of the invalid option here.

optstring - Variable in class gnu.getopt.Getopt

This is the string describing the valid short options.

ordering - Variable in class gnu.getopt.Getopt

Determines whether we permute arguments or not

P

PERMUTE - Static variable in class gnu.getopt.Getopt

PERMUTE is the default.

posixly_correct - Variable in class gnu.getopt.Getopt

The flag determines whether or not we operate in strict POSIX compliance

progname - Variable in class gnu.getopt.Getopt

Name to print as the program name in error messages.

R

REQUIRE_ORDER - Static variable in class gnu.getopt.Getopt

Describe how to deal with options that follow non-option ARGV-elements.

REQUIRED_ARGUMENT - Static variable in class gnu.getopt.LongOpt

Constant value used for the "has_arg" constructor argument.

RETURN_IN_ORDER - Static variable in class gnu.getopt.Getopt

RETURN_IN_ORDER is an option available to programs that were written to expect options and other ARGV-elements in any order and that care about the ordering of the two.

S

setArgv(String[]) - Method in class gnu.getopt.Getopt

Since in GNU getopt() the argument vector is passed back in to the function every time, the caller can swap out argv on the fly.

setOpterr(boolean) - Method in class gnu.getopt.Getopt

Normally Getopt will print a message to the standard error when an invalid option is encountered.

setOptind(int) - Method in class gnu.getopt.Getopt

This method allows the optind index to be set manually.

setOptstring(String) - Method in class gnu.getopt.Getopt

In GNU getopt, it is possible to change the string containg valid options on the fly because it is passed as an argument to getopt() each time.

V

val - Variable in class gnu.getopt.LongOpt

The value to store in "flag" if flag is not null, otherwise the equivalent short option character for this long option.
