Defined at line 117 of file ../../third_party/perfetto/include/perfetto/tracing/track_event_state_tracker.h

Interface used by the tracker to access tracing session and sequence state

and to report parsed track events.

Public Methods

void ~Delegate ()
SessionState * GetSessionState ()

Called to retrieve the session-global state shared by all sequences. The

returned pointer must remain valid (locked) throughout the call to

|ProcessTracePacket|.

void OnTrackUpdated (Track & )

Called when the metadata (e.g., name) for a track changes. |Track| can be

modified by the callback to attach user data.

void OnTrackEvent (const Track & , const ParsedTrackEvent & )

If the packet given to |ProcessTracePacket| contains a track event, this

method is called to report the properties of that event. Note that memory

pointers in |TrackEvent| will only be valid during this call.
