EnumeratedStringOption

public EnumeratedStringOption(String shortName,
                              String longName,
                              String description,
                              int minCount,
                              int maxCount,
                              Collection<String> allowedValues,
                              boolean ignoreCase)

Creates a new EnumeratedStringOption instance.

Parameters:

shortName - short name of the option (e.g. -t)

longName - long name of the option (e.g. --type)

description - helpful description of the option (printed for usage message)

minCount - minimum number of occurrences required for this option

maxCount - maximum number of occurrences required for this option

allowedValues - collection of possible values this option can take

ignoreCase - whether to ignore the case in string evaluations

EnumeratedStringOption

public EnumeratedStringOption(String shortName,
                              String longName,
                              String description,
                              boolean mandatory,
                              boolean allowMany,
                              Collection<String> allowedValues,
                              boolean ignoreCase)

Creates a new EnumeratedStringOption instance.

Parameters:

shortName - short name of the option (e.g. -t)

longName - long name of the option (e.g. --type)

description - helpful description of the option (printed for usage message)

mandatory - whether this option must be specified

allowMany - whether this option can take more than one value (i.e. be specified more than once)

allowedValues - collection of possible values this option can take

ignoreCase - whether to ignore the case in string evaluations

Method Detail

parseValue

protected String parseValue(String arg,
                            Locale locale)
                     throws OptionException

Parses the argument string for an option value, optionally using the specified locale for reference (e.g. for date parsing).

Specified by:

parseValue in class Option<String>

Parameters:

arg - string argument from which a value is to be parsed

locale - locale as specified when initializing the CLAParser instance

Returns:

Value of the parsed argument string

Throws:

OptionException - if a problem occurs while parsing the argument string

getType

public Class<String> getType()

Returns the class type of value this option can take.

Specified by:

getType in class Option<String>

Returns:

Class instance

getAllowedValuesString

public String getAllowedValuesString()

Returns the default version of the string denoting the values that can be assigned to this option.

Overrides:

getAllowedValuesString in class EnumeratedOption<String>

Returns:

comma-separated quoted string of allowed values
