All Known Implementing Classes:

BaseColumnCondition, BooleanCondition, CategoricalColumnCondition, DoubleColumnCondition, IntegerColumnCondition, LongColumnCondition, NullWritableColumnCondition, StringColumnCondition, StringRegexColumnCondition, TimeColumnCondition

public interface Condition
extends Serializable

The Condition interface defines a binary state that either holds/is satisfied for an example/sequence, or does not hold.
Example: number greater than x, String is one of {X,Y,Z}, etc.
