Class CollectionChangeRecord

    • Field Detail

      • addObjectList

        protected java.util.Map<ObjectChangeSet,​ObjectChangeSet> addObjectList
        Contains the added values to the collection and their corresponding ChangeSets.

      • orderedAddObjects

        protected java.util.List<ObjectChangeSet> orderedAddObjects
        Contains the added values to the collection and their corresponding ChangeSets in order.

      • orderedAddObjectIndices

        protected java.util.Map<ObjectChangeSet,​java.lang.Integer> orderedAddObjectIndices
        Contains the added values index to the collection.

      • orderedChangeObjectList

        protected java.util.List<OrderedChangeObject> orderedChangeObjectList
        Contains OrderedChangeObjects representing each change made to the collection.

      • orderedRemoveObjects

        protected java.util.Map<java.lang.Integer,​ObjectChangeSet> orderedRemoveObjects
        Contains the removed values to the collection and their corresponding ChangeSets.

      • orderedRemoveObjectIndices

        protected transient java.util.List<java.lang.Integer> orderedRemoveObjectIndices
        Contains the removed values index to the collection.

      • addOverFlow

        protected transient java.util.List<ObjectChangeSet> addOverFlow
        Contains a list of extra adds. These extra adds are used by attribute change tracking to replicate behavior when someone adds the same object to a list and removes it once. In this case the object should still appear once in the change set.

      • removeObjectList

        protected java.util.Map<ObjectChangeSet,​ObjectChangeSet> removeObjectList
        Contains the removed values from the collection and their corresponding ChangeSets.

      • orderHasBeenRepaired

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

    • Constructor Detail

      • CollectionChangeRecord

        public CollectionChangeRecord()
        This default constructor.

      • CollectionChangeRecord

        public CollectionChangeRecord​(ObjectChangeSet owner)
        Constructor for the ChangeRecord representing a collection mapping
        Parameters:
        owner - the changeSet that uses this record

    • Method Detail

      • addOrderedAdditionChange

        public void addOrderedAdditionChange​(java.util.List<java.lang.Object> orderedObjectsToAdd,
                                     java.util.Map<java.lang.Object,​java.lang.Integer> objectChangesIndices,
                                     UnitOfWorkChangeSet changeSet,
                                     AbstractSession session)
        This method takes a list of objects and converts them into ObjectChangeSets. This method should only be called from a ListContainerPolicy. Additions to the list are made by index, hence, the second Map of objectChangesIndices.

      • addOrderedRemoveChange

        public void addOrderedRemoveChange​(java.util.List<java.lang.Integer> indicesToRemove,
                                   java.util.Map objectChanges,
                                   UnitOfWorkChangeSet changeSet,
                                   AbstractSession session)
        This method takes a map of objects and converts them into ObjectChangeSets. This method should only be called from a ListContainerPolicy. Deletions from the list is made by index, hence, the second Vector of indicesToRemove.

      • getAddOverFlow

        public java.util.List<ObjectChangeSet> getAddOverFlow()
        Returns a list of extra adds. These extra adds are used by attribute change tracking to replicate behavior when someone adds the same object to a list and removes it once. In this case the object should still appear once in the change set.

      • hasChanges

        public boolean hasChanges()
        PUBLIC: Returns true if the change set has changes.
        Specified by:
        hasChanges in interface CollectionChangeRecord
        Returns:
        boolean

      • setAddObjectList

        public void setAddObjectList​(java.util.Map<ObjectChangeSet,​ObjectChangeSet> objectChangesList)
        Sets the Added objects list.

      • setRemoveObjectList

        public void setRemoveObjectList​(java.util.Map<ObjectChangeSet,​ObjectChangeSet> objectChangesList)
        Sets the removed objects list.

      • getOrderedAddObjects

        public java.util.List<ObjectChangeSet> getOrderedAddObjects()
        This method returns the collection of ChangeSets in the order they were added to the collection. This list includes those objects that were moved within the collection.

      • getOrderedAddObjectIndex

        public java.lang.Integer getOrderedAddObjectIndex​(ObjectChangeSet changes)
