)

Definition at line 75 of file nway_lru_cache.hpp.

Member Function Documentation

◆ Get() [1/2]

template<typename T , typename U , typename Hash = std::hash<T>, typename Equal = std::equal_to<T>>
std::optional< U > cache::NWayLRU< T, U, Hash, Equal >::Get ( const T &  key)
inline

Definition at line 29 of file nway_lru_cache.hpp.

◆ Get() [2/2]

template<typename T , typename U , typename Hash , typename Eq >
template<typename Validator >
std::optional< U > cache::NWayLRU< T, U, Hash, Eq >::Get ( const T &  key,
Validator  validator 
)

Definition at line 97 of file nway_lru_cache.hpp.

◆ GetOr()

template<typename T , typename U , typename Hash , typename Eq >
U cache::NWayLRU< T, U, Hash, Eq >::GetOr ( const T &  key,
const U &  default_value 
)

Definition at line 122 of file nway_lru_cache.hpp.

◆ GetSize()

template<typename T , typename U , typename Hash , typename Eq >
size_t cache::NWayLRU< T, U, Hash, Eq >::GetSize ( ) const

Definition at line 147 of file nway_lru_cache.hpp.

◆ Invalidate()

template<typename T , typename U , typename Hash , typename Eq >
void cache::NWayLRU< T, U, Hash, Eq >::Invalidate ( )

Definition at line 129 of file nway_lru_cache.hpp.

◆ InvalidateByKey()

template<typename T , typename U , typename Hash , typename Eq >
void cache::NWayLRU< T, U, Hash, Eq >::InvalidateByKey ( const T &  key)

Definition at line 112 of file nway_lru_cache.hpp.

◆ Put()

template<typename T , typename U , typename Hash , typename Eq >
void cache::NWayLRU< T, U, Hash, Eq >::Put ( const T &  key,
U  value 
)

Definition at line 86 of file nway_lru_cache.hpp.

◆ Read()

template<typename T , typename U , typename Hash , typename Equal >
void cache::NWayLRU< T, U, Hash, Equal >::Read ( dump::Reader &  reader)

Definition at line 188 of file nway_lru_cache.hpp.

◆ SetDumper()

template<typename T , typename U , typename Hash , typename Equal >
void cache::NWayLRU< T, U, Hash, Equal >::SetDumper ( std::shared_ptr< dump::Dumper >  dumper)

The dump::Dumper will be notified of any cache updates. This method is not thread-safe.

Definition at line 210 of file nway_lru_cache.hpp.

void cache::NWayLRU< T, U, Hash, Eq >::UpdateWaySize ( size_t  way_size)

Definition at line 157 of file nway_lru_cache.hpp.

◆ VisitAll()

template<typename T , typename U , typename Hash , typename Eq >
template<typename Function >
void cache::NWayLRU< T, U, Hash, Eq >::VisitAll ( Function  func) const

Iterates over all items. May be slow for big caches.

Definition at line 139 of file nway_lru_cache.hpp.
