 Description  « Hide
There are currently two identical interfaces called EngineBlob and EngineClob.
Merging these into a single interface would simplify some of the code handling Blob and Clob in the network server, and it also allows a leaner implementation of a stored procedure freeing LOB locators without knowing if the locator represents a Blob or a Clob.

ASF #642707 Sun Mar 30 11:09:05 UTC 2008 kristwaa DERBY-3576: Merge EngineBlob and EngineClob into a single interface.
Merged the two interfaces and added the method 'free'. There was no need to sepearate between a Blob and a Clob where the interface was used. If such a need arises, one should consider adding new interfaces extending EngineLOB.
