Direct Known Subclasses:

BackendOptions, ClassfileOptions, DisOptions, LexgenOptions, MjcCommonOptions, OptimizeOptions, TestingOptions

public abstract class Options

extends Object

This class implements basic option parsing. Subclasses add tool-specific options to the set of options that are accepted. Subclasses are typically generated using the option generating utility Main.

Field Detail

nonOptions

private String[] nonOptions

The array of non-option arguments.

name

private final String name

VERSION

private static final String VERSION

Xnoversion

private boolean Xnoversion

NOVERSION_CASE

private static final int NOVERSION_CASE

Options

public Options(String name)

Creates a new Option object.

Parameters:

name - the command name to pass to getopt

parseCommandLine

public boolean parseCommandLine(String[] argv)

parseCommandLine

public boolean parseCommandLine(String[] argv,
                                ArrayList infiles)

Parses and evaluates the command line arguments.

Parameters:

argv - the command line arguments

infiles - where to put non-option arguments

Returns:

true iff the command line was parsed successfully

setOption

public boolean setOption(String name,
                         Object newValue)

processOption

public boolean processOption(int code,
                             gnu.getopt.Getopt g)

Handles the option identified by the given code, perhaps using g to process any arguments to the option. This method is typically overridden in subclasses to process additional arguments with the subclass defering to the superclass if code is unknown.

Parameters:

g - the command line arguments

getDefaultValue

public Hashtable getDefaultValue()

Returns the default value

getCurrentValue

public Hashtable getCurrentValue()

Returns the current value

getSelectionList

public Hashtable getSelectionList()

Returns the list of selections for an option

getHelpString

public Hashtable getHelpString()
