Detailed Description​

class chronon::observe::FixedCounterStorage;

Sparse array of SimpleCounters for per-unit storage.

O(1) unchecked access via getUnchecked(). Memory cost is num_counters × 16 bytes.

Public Functions Documentation​

function size​

inline size_t size() const

function rollbackAllEpochs​

inline void rollbackAllEpochs()

function resetAll​

inline void resetAll()

function name​

inline const std::string & name() const

function info​

inline const CounterInfo & info(
    CounterId id
) const

function getUnchecked​

inline SimpleCounter & getUnchecked(
    CounterId id
)

Hot-path access by counter id (~1-2ns).

PRECONDITION: Counter must have been added via addCounter(); no bounds checking.

function getUnchecked​

inline const SimpleCounter & getUnchecked(
    CounterId id
) const

function get​

inline SimpleCounter & get(
    CounterId id
)

Bounds-checked access; grows storage if needed.

function get​

inline const SimpleCounter & get(
    CounterId id
) const

function forEach​

template <typename Fn >
inline void forEach(
    Fn && fn
) const

function ensureCapacity​

inline void ensureCapacity(
    size_t n
)

function counters​

inline std::vector< SimpleCounter > & counters()

function counters​

inline const std::vector< SimpleCounter > & counters() const

function commitAllEpochs​

inline void commitAllEpochs()

function addCounter​

inline CounterId addCounter(
    const std::string & name,
    const std::string & description ="",
    const std::string & unit =""
)

Register a counter dynamically.

Return: Counter ID assigned to this counter.

function FixedCounterStorage​

inline explicit FixedCounterStorage(
    std::string name
