Class SimpleDataSourceProvenance

java.lang.Object

org.tribuo.provenance.SimpleDataSourceProvenance

All Implemented Interfaces:

com.oracle.labs.mlrg.olcut.provenance.ObjectProvenance, com.oracle.labs.mlrg.olcut.provenance.Provenance, Serializable, Iterable<com.oracle.labs.mlrg.olcut.util.Pair<String,com.oracle.labs.mlrg.olcut.provenance.Provenance>>, DataProvenance, DataSourceProvenance

public class SimpleDataSourceProvenance
extends Object
implements DataSourceProvenance

This class stores a String describing the data source, along with a timestamp. It should not be used except for simple demos, or machine created data. It is vastly preferable to create a DataSource implementation with a specific provenance, rather than using this to construct an empty MutableDataset.
