The input filw in arff format.Abstract class gives default implementation of setSource methods.Abstract class for SaverReads a source that is in arff (attribute relation file format) format.Reads data from an ARFF file, either in incremental or batch mode.Writes to a destination in arff text format.Marker interface for a loader/saver that can retrieve instances in batch modeReads a file that is C45 format.Writes to a destination that is in the format used by the C4.5 algorithm.
Therefore it outputs a names and a data file.Utility routines for the converter package.Helper class for saving data to files.Helper class for loading data from files and URLs.Reads a source that is in comma separated or tab separated format.Writes to a destination that is in csv formatConnects to a database.Marker interface for a loader/saver that uses a databaseReads Instances from a Database.Writes to a database (tested with MySQL, InstantDB, HSQLDB).Interface to a loader/saver that loads/saves from a file source.Marker interface for a loader/saver that can retrieve instances incrementallyReads a source that is in libsvm format.
