forEachItem(fn: (r: KeyValueChangeRecord<K, V>) => void) : void
Iterate over all changes. KeyValueChangeRecord
will contain information about changes
to each item.
forEachPreviousItem(fn: (r: KeyValueChangeRecord<K, V>) => void) : void
Iterate over changes in the order of original Map showing where the original items have moved.
forEachChangedItem(fn: (r: KeyValueChangeRecord<K, V>) => void) : void
Iterate over all keys for which values have changed.
forEachAddedItem(fn: (r: KeyValueChangeRecord<K, V>) => void) : void
Iterate over all added items.
forEachRemovedItem(fn: (r: KeyValueChangeRecord<K, V>) => void) : void
Iterate over all removed items.
