All Implemented Interfaces:

ClassHierarchyParser, java.io.Serializable

public class ClassTreeArffFileParser

extends ClassTreeFileParser

Works as a ClassTreeFileParser, but expects the file to be of arff-format and to contain a comment-line providing as keyword "@hierarchy" followed by a hierarchy-string suitable for ClassTreeParser.setEncodedHierarchy(String encodedHierarchy). Thus the line should present three space separated tokens: the comment-symbol, the key-word, the encoded hierarchy.
