| CheckOptionHandler | Simple command line checking of classes that implement OptionHandler.
Usage:
CheckOptionHandler -W optionHandlerClassName -- test options
Valid options are: |
| CheckScheme | Abstract general class for testing schemes in Weka. |
| CheckScheme.PostProcessor | a class for postprocessing the test-data |
| ClassDiscovery | This class is used for discovering classes that implement a certain interface or a derived from a certain class. |
| ClassDiscovery.StringCompare | compares two strings. |
| ClassloaderUtil | Utility class that can add jar files to the classpath dynamically. |
| ContingencyTables | Class implementing some statistical routines for contingency tables. |
| Copyright | A class for providing centralized Copyright information. |
| Debug | A helper class for debug output, logging, clocking, etc. |
| Debug.Clock | A little helper class for clocking and outputting times. |
