Interface IWatcher

Returns true if tracked sub-properties of oldValue are different from (or not present in) the newValue. oldValue must be either the value parameter of watch (or one of the values of watchAll) or a sub-object of it.

See

• watch
• watchAll

Returns

true if tracked properties are different, otherwise - false.

Stops tracking of property access for the proxies associated with this watcher. Accessing proxy (or sub-proxy) properties after calling watcher.stop() will generate a runtime error.

Use this to make sure at runtime that no Proxy ends up in your derived data.

Unwraps the result derived from the input value proxy.

The result object may contain proxies if sub-objects of the input value proxy were put into the derived data as they are. This method will replace all proxy occurences with their underlying object's value so that the final result is proxy-free.

Returns

The result without proxies in any of its deep sub-properties.
