setStopOnBadOption

public Option setStopOnBadOption(boolean stopOnBadOption)

Description copied from interface: Option

stop parsing on the first unknown option. This allows one parser to get its own options and then pass the remaining options to another parser.

Specified by:

setStopOnBadOption in interface Option

setOptionsFirst

public Option setOptionsFirst(boolean optionsFirst)

Description copied from interface: Option

require options to precede args. Default is false, so options can appear between or after args.

Specified by:

setOptionsFirst in interface Option

isSet

public boolean isSet(java.lang.String name)

Description copied from interface: Option

test whether specified option has been explicitly set.

Specified by:

isSet in interface Option

Returns:

getObject

public java.lang.Object getObject(java.lang.String name)

Description copied from interface: Option

get value of named option as an Object. If multiple options given, this method returns the last one. Use Option.getObjectList(String) to get all values.

Specified by:

getObject in interface Option

Returns:

getObjectList

public java.util.List<java.lang.Object> getObjectList(java.lang.String name)

Description copied from interface: Option

get list of all Object values for named option.

Specified by:

getObjectList in interface Option

Returns:

getList

public java.util.List<java.lang.String> getList(java.lang.String name)

Description copied from interface: Option

get list of all values for named option.

Specified by:

getList in interface Option

Returns:

empty list if option not given and no default specified.

get

public java.lang.String get(java.lang.String name)

Returns:

getNumber

public int getNumber(java.lang.String name)

Description copied from interface: Option

get value of named option as a Number.

Specified by:

getNumber in interface Option

Returns:

argObjects

public java.util.List<java.lang.Object> argObjects()

Description copied from interface: Option

get remaining non-options args as Objects.

Specified by:

argObjects in interface Option

Returns:

args

Description copied from interface: Option

get remaining non-options args as Strings.

Specified by:

args in interface Option

Returns:

usage

public void usage()

Description copied from interface: Option

print usage message to System.err.

Specified by:

usage in interface Option

usageError

public java.lang.IllegalArgumentException usageError(java.lang.String s)

prints usage message and returns IllegalArgumentException, for you to throw.

Specified by:

usageError in interface Option

Returns:

IllegalArgumentException

parse

public Option parse(java.lang.Object[] argv)

Description copied from interface: Option

parse arguments.

parse

public Option parse(java.util.List<? extends java.lang.Object> argv,
