Class ImplementsMetaData

java.lang.Object

org.datanucleus.metadata.MetaData

org.datanucleus.metadata.ImplementsMetaData

All Implemented Interfaces:

Serializable

public class ImplementsMetaData
extends MetaData

The implements element declares a persistence-capable interface implemented by the persistence-capable class that contains this element. An extent of persistence-capable classes that implement this interface is managed by the JDO implementation. The extent can be used for queries or for iteration just like an extent of persistence-capable instances. The attribute name is required, and is the name of the interface. The java class naming rules apply: if the interface name is unqualified, the package is the name of the enclosing package.
