Upgrading to Newer Versions

Page contents show page contents

This page gives instructions for upgrading to newer versions of the C++ tracker.

Upgrading to v0.3.0

There are a few breaking changes in this release. Please make sure to:

  1. Remove the Tracker:: prefix when referring to event types, e.g., use ScreenViewEvent() instead of Tracker::ScreenViewEvent().
  2. Use the common tracker->track(event) function to track events (instead of tracker->track_self_describing_event(event), tracker->track_screen_view(event), …).
  3. Use the event.set_context(context) and event.set_true_timestamp(tt) setters instead of accessing event.contexts and event.true_timestamp directly.
  4. Event IDs are no longer accessible from the event objects but are returned from the tracker->track(event) function.
  5. Emitter and ClientSession no longer accept database path string for storage but require an instance of SqliteStorage (or other storage implementation, see the docs).
  6. Use #include "snowplow.hpp" to import all public APIs of the tracker instead of including individual files.

Upgrading to v0.2.0

This version adds a snowplow namespace to all tracker components. You will need to import specific or all types from the namespace:

using namespace snowplow;
Code language: C++ (cpp)

The constructor for ClientSession also changed, dropping the last argument for check_interval that is no longer necessary. Simply remove the last argument when creating an instance of ClientSession.
