Class MStreamableClob

java.lang.Object

com.mckoi.database.jdbc.AbstractStreamableObject

com.mckoi.database.jdbc.MStreamableClob

All Implemented Interfaces:

java.sql.Clob

class MStreamableClob
extends AbstractStreamableObject
implements java.sql.Clob

A Clob that is a large object that may be streamed from the server directly to this object. A clob that is streamable is only alive for the lifetime of the result set it is part of. If the underlying result set that contains this streamable clob is closed then this clob is no longer valid.
