AbstractHashableInstance 
Ancestor for instance classes that wraps around any WEKA Instance
and allow them to be used in data structures that make use of on object's
hash, like maps or hashtables.

AbstractSimpleOptionHandler 
Ancestor for Weka classes that use the ADAMS option handling framework.

HashableInstanceUsingString 
TODO: what this class does

HashableInstanceUsingSum 
Computes the hashcode as sum of the internal double values.

InstancesView 
Presents a view of an Instances object.

SAXDistance 
Implementing Euclidean distance (or similarity) function.
One object defines not one distance but the data model in which the distances between objects of that data model can be computed.
Attention: For efficiency reasons the use of consistency checks (like are the data models of the two instances exactly the same), is low.
For more information, see:
Wikipedia.

WeightedEuclideanDistance 
Implementing Euclidean distance (or similarity) function.
One object defines not one distance but the data model in which the distances between objects of that data model can be computed.
Attention: For efficiency reasons the use of consistency checks (like are the data models of the two instances exactly the same), is low.

WeightedEuclideanDistanceRidge

One object defines not one distance but the data model in which the distances between objects of that data model can be computed.

WekaOptionUtils 
Helper class for option parsing.

WekaPackageUtils 
Utility functions for Weka packages.
