Class ShortTopiaIdFactory

java.lang.Object

org.nuiton.topia.persistence.internal.ShortTopiaIdFactory

All Implemented Interfaces:

TopiaIdFactory

public class ShortTopiaIdFactory
extends Object
implements TopiaIdFactory

Does the same than DefaultTopiaIdFactory but produces shorter topiaId. The class-name part uses only simple class names, and the random part is base64 encoded.

Note: This TopiaIdFactory requires that you do not have several entities with the same simple class name.
