| a | -a flag |
| b@ | -b [classname] |
| c> | -c [filename] |
| d+ | -d [classname] (creates object via empty constructor) |
| e% | -e [number] (creates Double/Long instance depending on existing of a '.') |
| f/ | -f [url] |
| g: | -g [string] |
For example, the following allows command line flags of '-v -p string-value -f /dir/file'. The exclamation mark precede a mandatory option.
Options options = PatternOptionBuilder.parsePattern("vp:!f/");
TODO These need to break out to OptionType and also to be pluggable.
