Interface EngineLOB
public interface EngineLOB
Additional methods the embedded engine exposes on all of its large object
(LOB) implementations.
An internal API only, mainly for the network server.
Implementation note: If a new method is needed, that only applies to one specific large object type (for instance a Blob), one should consider creating a new interface that extends from this one.
