All Implemented Interfaces:

MappingCallbacks

public class OracleMapMapping
extends MapMapping

Oracle variant of the MapMapping for cases where we are serialising the field into a single column. This is necessary so we can intercept perform any necessary postInsert, postUpdate nonsense for inserting BLOBs
