Package com.mckoi.database.jdbc

Class MStreamableBlob

java.lang.Object

com.mckoi.database.jdbc.AbstractStreamableObject

com.mckoi.database.jdbc.MStreamableBlob

All Implemented Interfaces:

java.sql.Blob

class MStreamableBlob
extends AbstractStreamableObject
implements java.sql.Blob

A Blob that is a large object that may be streamed from the server directly to this object. A blob 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 If the underlying result set that contains this streamable blob is closed then this blob is no longer valid.
