Interface IDSource<T extends Serializable>

Type Parameters:

T - The type of ID returned by this source.

All Known Implementing Classes:

CompositeIDSource, IntSequenceIDSource, LongSequenceIDSource, StringPrefixIDSource

public interface IDSource<T extends Serializable>

Defines operations for classes that generate unique identifiers. Generated IDs must be of a Serializable type. The strategy used will vary between implementations. It may be a straightforward sequence or a more complex, less predictable algorithm.
