Class DisconnectedStream

java.lang.Object

org.brains2b.data.sql.lob.DisconnectedStream

All Implemented Interfaces:

org.brains2b.sql.meta.types.Stream

public class DisconnectedStream
extends java.lang.Object
implements org.brains2b.sql.meta.types.Stream

Implementation of Stream for database streams that are not connected to the stream in the database.

This implementation exists while some database (f.e. Oracle) will only allow access to the stream from the exact position within a ResultSet

This method is the simplest way to keep this stream by using LobCache as store the current content of the stream. This is not an ideal solution. It would be better to keep a cursor inside this stream, but this would require information on the unique identifiers of a record to retrieve the stream when requested
