class WrappedValue { static wrap(value: any): WrappedValue static unwrap(value: any): any static isWrapped(value: any): value is WrappedValue constructor(value: any) wrapped: any }
Wrapped values are unwrapped automatically during the change detection, and the unwrapped value is stored.
Example:
if (this._latestValue === this._latestReturnedValue) { return this._latestReturnedValue; } else { this._latestReturnedValue = this._latestValue; return WrappedValue.wrap(this._latestValue); // this will force update }
