/**
 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Query Type</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * 
 * 
 * 	The queryType defines a finder or select
 * 	query. It contains
 * 	    - an optional description of the query
 * 	    - the specification of the finder or select
 * 	      method it is used by
 * 		- an optional specification of the result type
 * 		  mapping, if the query is for a select method
 * 		  and entity objects are returned.
 * 		- the EJB QL query string that defines the query.
 * 
 * 	Queries that are expressible in EJB QL must use the ejb-ql
 * 	element to specify the query. If a query is not expressible
 * 	in EJB QL, the description element should be used to
 * 	describe the semantics of the query and the ejb-ql element
 * 	should be empty.
 * 
 * 	The result-type-mapping is an optional element. It can only
 * 	be present if the query-method specifies a select method
 * 	that returns entity objects.  The default value for the
 * 	result-type-mapping element is "Local".
