de.esoco.data.validate.TabularDataValidator

de.esoco.data.validate.QueryValidator

All Implemented Interfaces:

Validator<java.lang.String>, java.io.Serializable

public class QueryValidator
extends TabularDataValidator

A validator that is based on a storage query. This validator doesn't do any real validation because it assumes that the client only chooses elements that have been returned by the query which are always valid (although subclasses could implement additional validations if necessary). This validator serves mainly to hold information about a storage query which then can be used by a client to access a storage service.
