java.lang.Object org.apache.commons.beanutils.BasicDynaBean
public class BasicDynaBean
Minimal implementation of the DynaBean
interface. Can be
used as a convenience base class for more sophisticated implementations.
IMPLEMENTATION NOTE - Instances of this class that are accessed from multiple threads simultaneously need to be synchronized.
IMPLEMENTATION NOTE - Instances of this class can be
successfully serialized and deserialized ONLY if all
property values are Serializable
.
