weka.core.StringLocator
This class locates and records the indices of String attributes, recursively in case of Relational attributes. The indices are normally used for copying the Strings from one Instances object to another. @author fracpete (fracpete at waikato dot ac dot nz) @version $Revision: 6226 $ @see Attribute#STRING @see Attribute#RELATIONAL
