void UpdateStream (const view_tree::Snapshot & snapshot, StreamId stream_id, InternalTouchEvent event, bool is_end_of_stream, view_tree::BoundingBox view_bounds)

|GestureContender|

For |view_bounds| and |event.viewport| new values are only sent to the client when they've

changed from their last seen values.

Protected Methods

void Augment (const view_tree::Snapshot & snapshot, AugmentedTouchEvent & out_event, const InternalTouchEvent & in_event)

Allows subtypes to add augmentations to each event.

Defined at line 94 of file ../../src/ui/scenic/lib/input/touch_source_base.h

void TouchSourceBase (zx_koid_t channel_koid, zx_koid_t view_ref_koid, fit::function<void (StreamId, const std::vector<GestureResponse> &)> respond, GestureContenderInspector & inspector)

|respond_| must not destroy the TouchSourceBase object.

void WatchBase (std::vector<fuchsia_ui_pointer::TouchResponse> responses, fit::function<void (std::vector<AugmentedTouchEvent>)> callback)

Defined at line 312 of file ../../src/ui/scenic/lib/input/touch_source_base.cc

void UpdateResponseBase (const fuchsia_ui_pointer::TouchInteractionId & stream, fuchsia_ui_pointer::TouchResponse response, fit::function<void ()> callback)

Defined at line 390 of file ../../src/ui/scenic/lib/input/touch_source_base.cc

void PushEvent (StreamId stream_id, AugmentedTouchEvent event)

Pushes an event to be sent to the client. Default implementation queues the event for V1

hanging-get Watch() calls. Subclasses can override this to implement other delivery mechanisms.

Defined at line 269 of file ../../src/ui/scenic/lib/input/touch_source_base.cc

void CloseChannel (zx_status_t epitaph)

Closes the FIDL channel. This triggers the destruction of the TouchSourceBase object through

the error handler set in InputSystem. NOTE: No further method calls or member accesses should

be made after CloseChannel(), since they might be made on a destroyed object.
