public class PropertyDeltaImpl<T>
extends ItemDeltaImpl<PrismPropertyValue<T>,PrismPropertyDefinition<T>>
implements PropertyDelta<T>

Relative difference (delta) of a property values.

This class describes what values are to be added, removed or replaced in the property. The delta can be either add+delete or replace, but not both. It either describes what values to add and delete from the property (add+delete) or what is the new set of values (replace). Add+delete deltas can be merged without a loss. There are ideal for multi-value properties. If replace deltas are merged, only the last value will be present. These are better suited for single-value properties.

Description copied from class: ItemDeltaImpl

Filters out all delta values that are meaningless to apply. E.g. removes all values to add that the property already has, removes all values to delete that the property does not have, etc. Returns null if the delta is not needed at all. See description on the interface.

plusComparator - Comparator we want to use when determining skippability of values being added.
