Method Details

burstToken
Deprecated.Breakstokeninto its constituent parts using the following algorithm.- ignore the first character ("-")
- for each remaining character check if an
Optionexists with that id. - if an
Optiondoes exist then add that character prepended with "-" to the list of processed tokens. - if the
Optioncan have an argument value and there are remaining characters in the token then add the remaining characters as a token to the list of processed tokens. - if an
Optiondoes NOT exist ANDstopAtNonOptionIS set then add the special token "--" followed by the remaining characters and also the remaining tokens directly to the processed tokens list. - if an
Optiondoes NOT exist ANDstopAtNonOptionIS NOT set then add that character prepended with "-".
- Parameters:
token- The current token to be burststopAtNonOption- Specifies whether to stop processing at the first non-Option encountered.
-
flatten
protected String[] flatten(Options options, String[] arguments, boolean stopAtNonOption) throws ParseException Deprecated.An implementation of
Parser's abstractflattenmethod.The following are the rules used by this flatten method.
- if
stopAtNonOptionis true then do not burst anymore ofargumentsentries, just add each successive entry without further processing. Otherwise, ignorestopAtNonOption. - if the current
argumentsentry is "--" just add the entry to the list of processed tokens - if the current
argumentsentry is "-" just add the entry to the list of processed tokens - if the current
argumentsentry is two characters in length and the first character is "-" then check if this is a validOptionid. If it is a valid id, then add the entry to the list of processed tokens and set the currentOptionmember. If it is not a valid id andstopAtNonOptionis true, then the remaining entries are copied to the list of processed tokens. Otherwise, the current entry is ignored. - if the current
argumentsentry is more than two characters in length and the first character is "-" then we need to burst the entry to determine its constituents. For more information on the bursting algorithm seeburstToken. - if the current
argumentsentry is not handled by any of the previous rules, then the entry is added to the list of processed tokens.
- Specified by:
flattenin classParser- Parameters:
options- The command lineOptionsarguments- The command line arguments to be parsedstopAtNonOption- Specifies whether to stop flattening when an non option is found.- Returns:
- The flattened
argumentsString array. - Throws:
ParseException- if there are any problems encountered while parsing the command line tokens.
