void ApplySessionUpdatesAndSignalFences ()

Applies the most recently scheduled session update for each session and signals the release

fences of all Presents up to and including that update.

Defined at line 421 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

std::vector<scheduling::PresentId> GetRegisteredPresents (scheduling::SessionId session_id)

Gets the list of registered PresentIds for a particular |session_id|.

Defined at line 450 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

bool HasSessionUpdate (scheduling::SessionId session_id)

Returns true if |session_id| currently has a session update pending.

Defined at line 463 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

bool ReleaseFencesContain (scheduling::SessionId session_id, const zx::object_base & expected_fence)

Returns true if the pending release fences for `session_id` contain `expected_fence`.

Defined at line 468 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

bool ReleaseCountersContain (scheduling::SessionId session_id, const zx::object_base & expected_counter)

Returns true if the pending release counters for `session_id` contain `expected_counter`.

Defined at line 484 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

std::optional<zx::time> GetRequestedPresentationTime (scheduling::SchedulingIdPair id_pair)

Returns the requested presentation time for a particular |id_pair|, or std::nullopt if that

pair has not had a presentation scheduled for it.

Defined at line 501 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

bool IsDescendantOf (TransformHandle parent, TransformHandle child)

The parent transform must be a topology root or ComputeGlobalTopologyData() will crash.

Defined at line 510 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

std::shared_ptr<const UberStruct> GetUberStruct (Flatland * flatland)

Snapshots the UberStructSystem and fetches the UberStruct associated with |flatland|. If no

UberStruct exists for |flatland|, returns nullptr.

Defined at line 526 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

void UpdateLinks (TransformHandle root_transform)

Updates all Links reachable from |root_transform|, which must be the root transform of one of

the active Flatland instances.

Tests that call this function are testing both Flatland and LinkSystem::UpdateLinkWatchers().

Defined at line 546 of file ../../src/ui/scenic/lib/flatland/tests/flatland_unittest.h

void PresentWithArgs (Flatland * flatland, PresentArgs args, bool expect_success, cpp20::source_location location)

Calls Present() on a Flatland object and immediately triggers the session update

for all sessions so that changes from that Present() are visible in global systems. This is

primarily useful for testing the user-facing Flatland API.

|flatland| is a Flatland object constructed with the MockFlatlandPresenter owned by the

FlatlandTest harness. |expect_success| should be false if the call to Present() is expected to

trigger an error.
