 com.db4o.ext.Db4oUUID
| Db4oUUID | | public class Db4oUUID (Code) | | a unique universal identify for an object.
The db4o UUID consists of
two parts:
- an indexed long for fast access,
- the signature of the
com.db4o.ObjectContainer ObjectContainer the object was created with.
Db4oUUIDs are valid representations of objects over multiple
ObjectContainers

| Constructor Summary | |
| public | Db4oUUID(long longPart_, byte[] signaturePart_)
|
| Db4oUUID | | public Db4oUUID(long longPart_, byte[] signaturePart_)(Code) | | constructs a Db4oUUID from a long part and a signature part
Parameters:
longPart_ - the long part
Parameters:
signaturePart_ - the signature part |
| getLongPart | | public long getLongPart()(Code) | | returns the long part of this UUID.
To uniquely identify an object
universally, db4o uses an indexed long and a reference to the
Db4oDatabase object it was created on.
the long part of this UUID. |
| getSignaturePart | | public byte[] getSignaturePart()(Code) | | returns the signature part of this UUID.
To uniquely
identify an object universally, db4o uses an indexed long and a reference to
the Db4oDatabase singleton object of the
com.db4o.ObjectContainer ObjectContainer it was created on. This method
returns the signature of the Db4oDatabase object of the ObjectContainer: the
signature of the origin ObjectContainer.
the signature of the Db4oDatabase for this UUID. |
