  +--kodo.util.Id

All Implemented Interfaces:

Serializable

public class Id

extends Object

implements Serializable

Datastore identity type. Implementations may choose to use this type, or choose to use their own datastore identity values. The API for this class is aligned with JDO's single field identity; access to the internal state of Id objects through public fields is deprecated.

Method Detail

getKey

public long getKey()

Primary key.

getTargetClassName

public String getTargetClassName()

Target class name.

getTargetClass

public Class getTargetClass()

Target class. This method may return null if the instance has been serialized.

getTargetClass

public Class getTargetClass(JDOConfiguration conf,
                            ClassLoader pmLoader)

Target class. This method will attempt to instantiate the target class from the target class name if this instance has been serialized. Uses the given configuration's class resolver and the given persistence manager class loader, which may be null.

getTargetClass

public Class getTargetClass(ClassLoader loader)

Target class. This method will attempt to instantiate the target class from the target class name if this instance has been serialized. If the given class loader is null, the current thread's context loader will be used.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:
