EISOrderedCollectionChangeRecord

public EISOrderedCollectionChangeRecord(ObjectChangeSet owner,
 String attributeName,
 DatabaseMapping mapping)

Construct a ChangeRecord that can be used to represent the changes to an ordered collection.

Method Details

addAddedChangeSet

public void addAddedChangeSet(Object changeSet,
 int index)

Add an added change set.

addMovedChangeSet

public void addMovedChangeSet(Object changeSet,
 int oldIndex,
 int newIndex)

Add an moved change set.

addRemovedChangeSet

public void addRemovedChangeSet(Object changeSet,
 int index)

Add an removed change set.

getAddIndexes

public int[] getAddIndexes()

ADVANCED: Return the indexes into the new collection of the elements that were added.

Specified by:

getAddIndexes in interface EISOrderedCollectionChangeRecord

getAdds

public List getAdds()

ADVANCED: Return the entries for all the elements added to the new collection. The contents of this collection is determined by the mapping that populated it

Specified by:

getAdds in interface EISOrderedCollectionChangeRecord

getMoveIndexPairs

public int[][] getMoveIndexPairs()

ADVANCED: Return the indexes of the elements that were simply moved within the collection. Each element in the outer array is another two-element array where the first entry [0] is the index of the object in the old collection and the second entry [1] is the index of the object in the new collection. These two indexes can be equal.

Specified by:

getMoveIndexPairs in interface EISOrderedCollectionChangeRecord

getMoves

public List getMoves()

ADVANCED: Return the entries for all the elements that were simply shuffled within the collection. The contents of this collection is determined by the mapping that populated it

Specified by:

getMoves in interface EISOrderedCollectionChangeRecord

getNewCollection

ADVANCED: Return the indexes into the old collection of the elements that were removed.

Specified by:

getRemoveIndexes in interface EISOrderedCollectionChangeRecord

getRemoves

public List getRemoves()

ADVANCED: Return the entries for all the elements removed from the old collection. The contents of this collection is determined by the mapping that populated it

Specified by:

getRemoves in interface EISOrderedCollectionChangeRecord

hasChanges

public boolean hasChanges()

Return whether any changes have been recorded with the change record.

Specified by:

hasChanges in interface CollectionChangeRecord

Specified by:
