Class Args

java.lang.Object
  org.neo4j.helpers.Args

public class Args
extends Object

Parses a String[] argument from a main-method. It expects values to be either key/value pairs or just "orphan" values (w/o a key associated).

A key is defined with one or more dashes in the beginning, for example:

   '-path'
   '--path'
 

A key/value pair can be either one single String from the array where there's a '=' delimiter between the key and value, like so:

   '--path=/my/path/to/something'
 

...or consist of two (consecutive) strings from the array, like so:

   '-path' '/my/path/to/something'
