class FIFFLIB::FiffDataRef

External data reference: type, endian, byte size and offset into an external FIFF payload file.

Mirrors the original fiffDataRefRec exactly: a 24-byte record made of two qint32 (type, endianness flag) followed by two qint64 (payload size in bytes, byte offset into the external file). The 64-bit fields let referenced payloads exceed 2 GiB, which is required by long continuous Neuromag recordings split into multi-file FIFF trees.

Public Methods​

FiffDataRef()​

Default constructor.

Initializes all fields to zero.

~FiffDataRef()​

Destroys the FiffDataRef.

Static Methods​

storageSize()​

Size of the old struct (fiffDataRefRec) 2int + 2long = 24 + 28 = 24.

Returns:

  • qint32 — the size of the old struct fiffDataRefRec.
