Detailed Description

pair of input and output size

The Metadata required to decoded the CTF of particular detector.

Typedef Documentation

BufferType

using o2::ctf::BufferType = typedef uint8_t

This is the type of the vector to be used for the EncodedBlocks buffer allocation.

Definition at line 86 of file EncodedBlocks.h.

DetID

typedef o2::detectors::DetID o2::ctf::DetID

this is a base class for particular detector CTF coder/decoder, provides common interface to create external entropy encoders/decoders

Definition at line 51 of file CTFCoderBase.h.

FTrans

using o2::ctf::FTrans = typedef o2::rans::DenseHistogram<int32_t>

Definition at line 95 of file CTFWriterSpec.cxx.
