*** ONLY FOR USE IN TESTS ***

This is a sensitive protocol. It provides unlimited access to the global

view tree. Hand it out ONLY to test components.

Production uses should obtain observation protocols through a graphics

factory function (see |fuchsia.ui.composition.ViewBoundProtocols|), which

securely ties observation protocols to a specific view client.

Public Methods

void ~Registry ()

void RegisterGlobalViewTreeWatcher (::fidl::InterfaceRequest< ::fuchsia::ui::observation::geometry::ViewTreeWatcher> watcher, RegisterGlobalViewTreeWatcherCallback callback)

Sets up a channel for receiving global view geometry.

This method may be called multiple times to obtain multiple geometry

`ViewTreeWatcher`s, if necesary. However, typical test usage is to

obtain just one geometry `ViewTreeWatcher` in the test component.

Flow control. The caller is allowed at most one in-flight call at a

time. Subsequent calls must wait until the acknowledgment returns.

Non-compliance results in channel closure.

Client can freely disconnect this `Registry` endpoint after this method

returns.
