org.apache.commons.cli.Parser

All Implemented Interfaces:

CommandLineParser

Direct Known Subclasses:

BasicParser, GnuParser, PosixParser

Deprecated.

Since 1.3, the two-pass parsing with the flatten method is not enough flexible to handle complex cases.

@Deprecated
public abstract class Parser
extends Object
implements CommandLineParser

Creates CommandLine instances.

Method Detail

checkRequiredOptions

protected void checkRequiredOptions()
                             throws MissingOptionException

Deprecated.

Throws a MissingOptionException if all of the required options are not present.

Throws:

MissingOptionException - if any of the required Options are not present.

flatten

protected abstract String[] flatten(Options opts,
                                    String[] arguments,
                                    boolean stopAtNonOption)
                             throws ParseException

Deprecated.

Subclasses must implement this method to reduce the arguments that have been passed to the parse method.

Parameters:

opts - The Options to parse the arguments by.

arguments - The arguments that have to be flattened.

stopAtNonOption - specifies whether to stop flattening when a non option has been encountered.

Returns:

a String array of the flattened arguments.

Throws:

ParseException - if there are any problems encountered while parsing the command line tokens.

getOptions

protected Options getOptions()

Deprecated.

Gets the options.

Returns:

the options.

getRequiredOptions

protected List getRequiredOptions()

Deprecated.

Gets the required options.

Returns:

the required options.

parse

public CommandLine parse(Options options,
                         String[] arguments)
                  throws ParseException

Deprecated.

Parses the specified arguments based on the specified Options.

Specified by:

parse in interface CommandLineParser

Parameters:

options - the Options.

arguments - the arguments.

Returns:

the CommandLine.

Throws:

ParseException - if there are any problems encountered while parsing the command line tokens.

parse

public CommandLine parse(Options options,
                         String[] arguments,
