vspline::buffer_handling< _vtype, _dtype, _vsize > Class Template Reference

buffer_handling provides services needed for interfacing with a buffer of simdized/goading data. The init() routine receives two views: one to a buffer accepting incoming data, and one to a buffer providing results. Currently, all filters used in vspline operate in-place, but the two-argument form leaves room to manoevre. get() and put() receive 'bundle' arguments which are used to transfer incoming data to the view defined in in_window, and to transfer result data from the view defined in out_window back to target memory.
