  edu.udo.cs.yale.operator.Operator

          edu.udo.cs.yale.operator.io.CSVExampleSource

All Implemented Interfaces:

ConfigurationListener

public class CSVExampleSource
extends AbstractWekaExampleSource

This operator can read csv files. All values must be separated by "," (without blanks) or by tabs. The first line is used for attribute names. For other file formats or column separators you can use in almost all cases the operator SimpleExampleSource or, if this is not sufficient, the operator ExampleSource.
