Class UpdatePlan

java.lang.Object
  com.bea.ld.dsmediator.update.UpdatePlan

All Implemented Interfaces:

java.io.Serializable

public class UpdatePlan

extends java.lang.Object

implements java.io.Serializable

Update plan is a sequence of nodes decomposed from original View SDO object. Each node in sequence can either be a SDO instance only or a SDO with a sub-update plan, which is another sequence of nodes. in View SDO, if a parent DataObject get updated, at least partially due to the changes on the DataObjects nested inside it, then SDO instances corresponding to those children DataObjects will be addChild into sub-update plan. Update plan contains inserted, updated, deleted and unchanged SDO instances as well. Update plan is constructed from a LinkedHashMap tree, independent SDO instances are stored in the same level and update sequence on their source dataobjects is preserved
