org.springframework.data.cassandra.core.query.Criteria

All Implemented Interfaces:

CriteriaDefinition

public class Criteria
extends Object
implements CriteriaDefinition

Basic class for creating queries. It follows a fluent API style so that you can easily create a CriteriaDefinition. Static import of the 'Criteria.where' method will improve readability.
