Description

An object describing the changes in the Map or {[k:string]: string} since last time KeyValueDiffer#diff() was invoked.

Members

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.
