Class DirectCollectionChangeRecord

    • Field Detail

      • addObjectMap

        protected HashMap addObjectMap

      • removeObjectMap

        protected HashMap removeObjectMap

      • commitAddMap

        protected HashMap commitAddMap
        Contains the number of objects that must be inserted to once the value is removed in the database as a delete where value = "value" will remove all instances of that value in the database not just one.

      • changedIndexes

        protected Map changedIndexes
        Used only in case listOrderField != null in the mapping. Maps each object which has been added or removed or which order in the list has changed to an array of two (non-intersecting) sets of indexes - old and new.

      • oldSize

        protected int oldSize

      • newSize

        protected int newSize

      • isFirstToAddAlreadyInCollection

        protected boolean isFirstToAddAlreadyInCollection

      • isFirstToRemoveAlreadyOutCollection

        protected boolean isFirstToRemoveAlreadyOutCollection

      • isFirstToAdd

        protected boolean isFirstToAdd

      • isFirstToRemove

        protected boolean isFirstToRemove

      • orderHasBeenRepaired

        protected boolean orderHasBeenRepaired
        Indicates whether IndirectList's order has been repaired.

    • Constructor Detail

      • DirectCollectionChangeRecord

        public DirectCollectionChangeRecord()
        This default constructor.

      • DirectCollectionChangeRecord

        public DirectCollectionChangeRecord​(ObjectChangeSet owner)
        This constructor returns a changeRecord representing the DirectCollection mapping.

    • Method Detail

      • addAdditionChange

        public void addAdditionChange​(HashMap additions,
                              HashMap databaseCount)
        This method takes a map of primitive objects and adds them to the add list. The map stores the number of times the object is in the list.

      • addAdditionChange

        public void addAdditionChange​(Object key,
                              Integer count)
        This method takes a single addition value and records it.

      • addRemoveChange

        public void addRemoveChange​(HashMap additions,
                            HashMap databaseCount)
        This method takes a hashtable of primitive objects and adds them to the remove list. Each reference in the hashtable lists the number of this object that needs to be removed from the collection.

      • addRemoveChange

        public void addRemoveChange​(Object key,
                            Integer count)
        This method takes a single remove change and integrates it with this changeset.

      • setCommitAddition

        public void setCommitAddition​(Hashtable additions)
        This method takes a hashtable of primitives and adds them to the commit list. This count value provided is the number of instances that will need to be inserted into the database once a remove has occurred. This is only set once for each object type.

      • storeDatabaseCounts

        public void storeDatabaseCounts​(Object collection,
                                ContainerPolicy containerPolicy,
                                AbstractSession session)
        This method will iterate over the collection and store the database counts for the objects within the collection, this is used for minimal updates.

      • incrementDatabaseCount

        public void incrementDatabaseCount​(Object object)
        Increment the count for object

      • decrementDatabaseCount

        public void decrementDatabaseCount​(Object object)
        Decrement the count for object

      • getAddObjectMap

        public HashMap getAddObjectMap()
        This method returns the collection of objects that were added to the collection.

      • getCommitAddMap

        public HashMap getCommitAddMap()
        This method returns the collection of objects that were added to the collection.

      • getRemoveObjectMap

        public HashMap getRemoveObjectMap()
        This method returns the collection of objects that were removed from the collection.

      • hasChanges

        public boolean hasChanges()
        Returns true if the change set has changes.

      • setFirstToAddAlreadyInCollection

        public void setFirstToAddAlreadyInCollection​(boolean flag)

      • isFirstToAddAlreadyInCollection

        public boolean isFirstToAddAlreadyInCollection()

      • setFirstToRemoveAlreadyOutCollection

        public void setFirstToRemoveAlreadyOutCollection​(boolean flag)

      • isFirstToRemoveAlreadyOutCollection

        public boolean isFirstToRemoveAlreadyOutCollection()

      • setChangedIndexes

        public void setChangedIndexes​(Map changedIndexes)

      • getChangedIndexes

        public Map getChangedIndexes()
