Class LogResultStructureResultHandler

java.lang.Object

de.lmu.ifi.dbs.elki.result.LogResultStructureResultHandler

All Implemented Interfaces:

ResultHandler, ResultProcessor

@Description(value="Development result handler that merely logs the structure of the result tree.")
public class LogResultStructureResultHandler
extends java.lang.Object
implements ResultHandler

A result handler to help with ELKI development that will just show the structure of the result object. This class is mostly useful when you are implementing your own result handlers or evaluators, as it will print a simple representation of the result tree. For using this, make sure to set the logging level appropriately by using -verbose. TODO: transform this into an evaluator, then visualize, too?

0.5.5
