Interface Summary

AdditionalMeasureProducer	Interface to something that can produce measures other than those calculated by evaluation modules.
ClassHierarchy	Interface for representations of a hierarchy of classes.
Copyable	Interface implemented by classes that can produce "shallow" copies of their objects.
Drawable	Interface to something that can be drawn as a graph.
Matchable	Interface to something that can be matched with tree matching algorithms.
OptionHandler	Interface to something that understands options.
Randomizable	Interface to something that has random behaviour that is able to be seeded with an integer.
Summarizable	Interface to something that provides a short textual summary (as opposed to toString() which is usually a fairly complete description) of itself.
WeightedInstancesHandler	Interface to something that makes use of the information provided by instance weights.
