Class BasicDynaBean
java.lang.Object
org.apache.commons.beanutils.BasicDynaBean
- DynaBean, Serializable
public class BasicDynaBean
extends java.lang.Object
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
.
