Interface QueryCriteria

All Known Implementing Classes:

SimpleQueryCriteria

public interface QueryCriteria

Criteria is a simplified representation of conditions the entities targeted by a query have to satisfy and that constrains the query of such entities.

Instead of providing a full representation of a criteria API by which criterion objects can be composing programmatically and that wraps each underlying persistence-specific criteria API we use, we prefer to let the developers provide their own implementation of the criteria by extendings this interface and by adapting it to their purpose.
