Detailed Description

Base class for timeline data providers.

Provides common functionality for all timeline data provider types. This is an abstract base class that defines the interface that all derived provider classes must implement.

inline

Generate the event sequence to be used during realtime processing.

To be called as needed from the UI thread when a new cache is requested.

Template Parameters
