flatten

protected java.lang.String[] flatten(Options options,
                                     java.lang.String[] arguments,
                                     boolean stopAtNonOption)
                              throws ParseException

Deprecated.

An implementation of Parser's abstract flatten method.

The following are the rules used by this flatten method.

1. if stopAtNonOption is true then do not burst anymore of arguments entries, just add each successive entry without further processing. Otherwise, ignore stopAtNonOption.
2. if the current arguments entry is "--" just add the entry to the list of processed tokens
3. if the current arguments entry is "-" just add the entry to the list of processed tokens
4. if the current arguments entry is two characters in length and the first character is "-" then check if this is a valid Option id. If it is a valid id, then add the entry to the list of processed tokens and set the current Option member. If it is not a valid id and stopAtNonOption is true, then the remaining entries are copied to the list of processed tokens. Otherwise, the current entry is ignored.
5. if the current arguments entry 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 see burstToken.
6. if the current arguments entry is not handled by any of the previous rules, then the entry is added to the list of processed tokens.

Specified by:

flatten in class Parser

Parameters:

options - The command line Options

arguments - The command line arguments to be parsed

stopAtNonOption - Specifies whether to stop flattening when an non option is found.

Returns:

The flattened arguments String array.

Throws:

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

gobble

private void gobble(java.util.Iterator<java.lang.String> iter)

Deprecated.

Adds the remaining tokens to the processed tokens list.

Parameters:

iter - An iterator over the remaining tokens

processNonOptionToken

private void processNonOptionToken(java.lang.String value,
                                   boolean stopAtNonOption)

Deprecated.

Add the special token "--" and the current value to the processed tokens list. Then add all the remaining argument values to the processed tokens list.

Parameters:

value - The current token

processOptionToken

private void processOptionToken(java.lang.String token,
                                boolean stopAtNonOption)

Deprecated.

If an Option exists for token then add the token to the processed list.

If an Option does not exist and stopAtNonOption is set then add the remaining tokens to the processed tokens list directly.

Parameters:

token - The current option token

stopAtNonOption - Specifies whether flattening should halt at the first non option.

burstToken

protected void burstToken(java.lang.String token,
                          boolean stopAtNonOption)

Deprecated.

Breaks token into its constituent parts using the following algorithm.

• ignore the first character ("-")
• for each remaining character check if an Option exists with that id.
• if an Option does exist then add that character prepended with "-" to the list of processed tokens.
• if the Option can 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 Option does NOT exist AND stopAtNonOption IS set then add the special token "--" followed by the remaining characters and also the remaining tokens directly to the processed tokens list.
• if an Option does NOT exist AND stopAtNonOption IS NOT set then add that character prepended with "-".

Parameters:

token - The current token to be burst

stopAtNonOption - Specifies whether to stop processing at the first non-Option encountered.
