public class LevelSetFactory
extends Object

Author:

erwin This class encapsulates all known implementations for Level Sets and their parameters. This makes it (hopefully) easier to implement future variants of the LevelSets without having to rework the dialog. This class returns a Level Set instance as requested in getImplementation (as a factory should) Parameters for each implementation (which may differ) are all handled in this factory. A calling class can get the names of each implementation, the parameters used in each implementation, their names and the suggested defaults. To add a Level Set implementation, the implementer has to do following: 1) Each parameter ever used in any implementation must be listed in the enum Parameter 2) Add the corresponding free text description for the parameter in constructor param_desc.put 3) Add the parameters that the implementation uses in def_global 4) Create a case in getImplementation to create an instance 5) Right now the class only deals with Double parameters. Anything else should be created as nested class and must be dealt with in dialog.
