enum TrackStatePropMask

Collection of bit masks to enable steering which components of a track state should be initialized, and which should be left invalid.

These mask values can be combined using binary operators, so (TrackStatePropMask::Predicted | TrackStatePropMask::Jacobian) will instruct allocating storage for both predicted parameters (including covariance) and a jacobian. The enum is used as a strong type wrapper around the bits to prevent autoconversion from integer


enumerator None
enumerator Predicted
enumerator Filtered
enumerator Smoothed
