Class PatternOptionBuilder

java.lang.Object
  extended by org.apache.commons.cli.PatternOptionBuilder

public class PatternOptionBuilder
extends Object

Allows Options to be created from a single String. The pattern contains various single character flags and via an optional punctuation character, their expected type.

a-a flag
b@-b [classname]
c>-c [filename]
d+-d [classname] (creates object via empty contructor)
e%-e [number] (creates Number instance)
f/-f [url]

For example, the following allows command line flags of '-v -p string-value -f /dir/file'.

Options options = PatternOptionBuilder.parsePattern("vp:f/");

TODO These need to break out to OptionType and also to be pluggable.
