Detailed Description

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.

Constructor & Destructor Documentation

◆ FiffDataRef()

FIFFLIB::FiffDataRef::FiffDataRef ( )

inline

Member Function Documentation

◆ storageSize()

qint32 FIFFLIB::FiffDataRef::storageSize ( )

inlinestatic

Size of the old struct (fiffDataRefRec) 2*int + 2*long = 2*4 + 2*8 = 24.

Returns: the size of the old struct fiffDataRefRec.
