Detailed Description

Implementation of MNELIB::MNERawData.

Author: Christoph Dinh chris.nosp@m.toph.nosp@m..dinh.nosp@m.@mne.nosp@m.-cpp..nosp@m.org

Since: 2.0.0

Date: March 2026

Implements buffer-list construction by walking the FIFFB_RAW_DATA block tree, per-buffer file seek/read with on-the-fly type conversion to single precision and SSP/CTF application as the buffers stream through.
