Examples of CriteriaSelector

org.teiid.query.sql.proc.CriteriaSelector

This class represents the criteria present on the user's query. The type of criteria and the elements on which it is specified are listed in this object, this object is used by HasCriteria and TranslateCriteria objects to determine if a particular type of criteria is present on one or more elements on a user's query
