Class StringQuerySource

  • public class StringQuerySource
extends QuerySource
    interprets the query id as an HQL query. In this implementation, no parsing is done at lookup or creation-time, but an implementation which does so is conceivable. The id itself is added to the list of parameters with the name StringQuery.STRING This query source should be placed at the end of the array of query sources provided to QueryFactory because it will always return a Query regardless of the id. An exception will be thrown at execution time if the HQL is invalid.
