const &

Get i-th knot from an explicit flat buffer pointer. Use this instead of getKnot() on the zero-copy path.

GPUd() [3/4]

template<typename DataT >

o2::gpu::Spline1DContainer< DataT, NoFlatObject >::GPUd ( ) const

inline

Get the knot array from an explicit flat buffer pointer. Use this instead of getKnots() when the object was copied across process boundaries and mFlatBufferPtr has not been fixed up (zero-copy path).
