  constructor(value: any)

}

Description

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
 }
