◆ operator bool()

ROOT::Internal::RNTupleFileWriter::RFileRFile::operator bool ( ) const

inline

◆ ReserveBlobKey()

std::uint64_t ROOT::Internal::RNTupleFileWriter::RFileRFile::ReserveBlobKey	(	size_t	nbytes,
		size_t	len,
		unsigned char	keyBuffer[kBlobKeyLen] = nullptr )

Reserves an RBlob opaque key as data record and returns the offset of the record.

If keyBuffer is specified, it must be written before the returned offset. (Note that the array type is purely documentation, the argument is actually just a pointer.)

void ROOT::Internal::RNTupleFileWriter::RFileRFile::Write	(	const void *	buffer,
		size_t	nbytes,
