Class MyByteBlob

java.lang.Object
  cgl.util.MyByteBlob

All Implemented Interfaces:

java.sql.Blob

public class MyByteBlob

extends java.lang.Object

implements java.sql.Blob

Screwy wrapper class so that we can insert a Blob into the database from a byte array. Includes more screwy stuff for Oracle specific updating of a blob (the only way to insert a new blob).
