class Flatland

Defined at line 55 of file ../../src/ui/scenic/lib/flatland/flatland.h

Implements the `fuchsia.ui.composition.Flatland` protocol. It is intended to run on its own

thread/dispatcher, and communicates with the main/render thread(s) via the UberStruct mechanism,

as well as other interfaces such as FlatlandPresenter. Because `fuchsia.ui.composition.Flatland`

is a stateful protocol, each client is connected to a different Flatland object.

Instantiates a new Flatland object and binds it to serve the Flatland protocol over the

`server_end` channel. Method invocations received on this channel will be serviced on

the thread managed by `dispatcher_holder`.

The `destroy_instance_function` is called to notify the instance's manager that the instance

should be destroyed. This function is invoked on the thread owned by `dispatcher_holder`. When

this function is invoked, the client FIDL connection has already been closed. There are two

situations that result in the invocation of `destroy_instance_function`:

- the client closes the FIDL channel

- the client makes illegal use of the API (or associated APIs like ChildViewWatcher)

`flatland_presenter`, `link_system`, `uber_struct_queue`, and `buffer_collection_importers`

allow this Flatland object to access resources shared by all Flatland instances for actions

like frame scheduling, linking, buffer allocation, and presentation to the global scene graph.

void Flatland (const Flatland & )

Because this object captures its "this" pointer in internal closures, it is unsafe to copy or

move it. Disable all copy and move operations.

void SetLayerStackData (TransformHandle stack_handle, std::span<const LayerHandle> layers)

Replaces the stack's entire existing layer list with `layers`. This operation

adjusts each affected LayerObject's ref_count: +1 for each handle newly added

(per occurrence) and -1 for each handle removed from the stack (via ReleaseLayerObject).

A pure reorder is ref-count-neutral. Layers destroyed by the decrement follow

the normal ReleaseLayerObject path (bound image into the release machinery).

Every handle in `layers` must exist in layer_objects_.

std::vector<allocation::GlobalImageId> CleanupFlatland2StateForTest (const std::vector<TransformHandle> & dead_handles)

Test-only accessor/mutators

TODO(https://fxbug.dev/523371761): once everything lands, verify whether these are necessary

to keep, or whether they are well-covered by tests for production callers such as

`CreateImage()` and `ProcessDeadTransforms()`.
