/**
* Specifies and names a stored procedure, its parameters, and its result type.
*
* The NamedStoredProcedureQuery annotation can be applied to an
* entity or mapped superclass.
*
*
The name element is the name that is passed as an argument to the
* {@link EntityManager#createNamedStoredProcedureQuery}
* method to create an executable StoredProcedureQuery object.
* Names are scoped to the persistence unit.
*
*
The procedureName element is the name of the stored procedure in
* the database.
*
*
The parameters of the stored procedure are specified by the
* parameters element. All parameters must be specified in the order in
* which they occur in the parameter list of the stored procedure.
*
*
The resultClasses element refers to the class (or classes) that are
* used to map the results. The resultSetMappings element names one or
* more result set mappings, as defined by the {@link SqlResultSetMapping}
* annotation.
*
*
If there are multiple result sets, it is assumed that they will be
* mapped using the same mechanism — e.g., either all via a set of
* result class mappings or all via a set of result set mappings. The
* order of the specification of these mappings must be the same as
* the order in which the result sets will be returned by the stored
* procedure invocation. If the stored procedure returns one or more
* result sets and no resultClasses or resultSetMappings
* element is specified, any result set will be returned as a list of type
* Object[]. The combining of different strategies for the mapping of
* stored procedure result sets is undefined.
*
*
The hints element may be used to specify query properties and
* hints. Properties defined by this specification must be observed by
* the provider. Vendor-specific hints that are not recognized by a
* provider must be ignored.
*
*
All parameters of a named stored procedure query must be specified
* using the StoredProcedureParameter annotation.
