摘要
A technique used with PL/SQL routines that are wrappers for Java routines which permits a PL/SQL wrapper routine to supply a Java class to the Java routine executed by the wrapper routine. The invocation of the wrapper routine includes a parameter value that specifies the class. The relational database system in which the PL/SQL routine is being executed includes a row source for a row that relates the parameter value to a definition for the class that is to be supplied. When the PL/SQL routine is executed, the PL/SQL routine uses the parameter value to query the row source and provides the class definition returned by the query to the Java routine. The technique is employed in a network analysis API that is made up of PL/SQL wrapper routines to supply classes defining network constraints to the Java routines executed by the wrapper routines.
