KeyValueChanges

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

interface KeyValueChanges<K, V> {
  forEachItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void
  forEachPreviousItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void
  forEachChangedItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void
  forEachAddedItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void
  forEachRemovedItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void
}

Methods

forEachItem()
Iterate over all changes. KeyValueChangeRecord will contain information about changes to each item.
forEachItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void Parameters fn Type: (r: KeyValueChangeRecord) => void. Returns void

forEachPreviousItem()
Iterate over changes in the order of original Map showing where the original items have moved.
forEachPreviousItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void Parameters fn Type: (r: KeyValueChangeRecord) => void. Returns void

forEachChangedItem()
Iterate over all keys for which values have changed.
forEachChangedItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void Parameters fn Type: (r: KeyValueChangeRecord) => void. Returns void

forEachAddedItem()
Iterate over all added items.
forEachAddedItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void Parameters fn Type: (r: KeyValueChangeRecord) => void. Returns void

forEachRemovedItem()
Iterate over all removed items.
forEachRemovedItem(fn: (r: KeyValueChangeRecord<K, V>) => void): void Parameters fn Type: (r: KeyValueChangeRecord) => void. Returns void
