Detailed Description

Definition at line 1 of file playlist_position_reference_tracker.h.

Constructor & Destructor Documentation

playlist_position_reference_tracker::playlist_position_reference_tracker ( bool  p_trackitem = true )

inline

Parameters

p_trackitem

Specifies whether we want to track some specific item rather than just an offset in a playlist. When set to true, item index becomes invalidated when the item we're tracking is removed.
