com.datastax.driver.mapping.MappedClassesOnlyHierarchyScanStrategy

All Implemented Interfaces:

HierarchyScanStrategy

public class MappedClassesOnlyHierarchyScanStrategy
extends Object
implements HierarchyScanStrategy

A HierarchyScanStrategy that excludes all ancestors of mapped classes, thus restricting class scan to the mapped classes themselves.

This strategy can be used instead of DefaultHierarchyScanStrategy to achieve pre-JAVA-541 behavior.
