public abstract class Condition
extends java.lang.Object
implements Predicate, java.io.Serializable

An abstract base class for all conditions that allow to check whether a value that is associated with an Attribute satisfies a certain condition.

This class implements the method Predicate.test(Object) to check whether an example (given as an AttributeMap) satisfies a condition or not.
