java.lang.Objectorg.apache.openjpa.jdbc.sql.AbstractResult
public abstract class AbstractResult
A Result implementation designed to be subclassed easily by
implementations. All get<type> calls are delegated to
the getObjectInternal(Object,int,Object,Joins) method, which
should be implemented by subclasses along with nextInternal(),
containsInternal(java.lang.Object, org.apache.openjpa.jdbc.sql.Joins), and Result.size().
Most of the methods of this class will accept return values from
getObjectInternal(Object,int,Object,Joins) that are not exactly
the right type. For example, any numeric type can be returned as any
Number type, and dates, locales, characters, and booleans can be
returned as strings.
