Detailed Description

template<typename K, typename T>
class aurore::LRUCache< K, T >

LRU cache If the reference count is not 0, the cache will never expire. Cache items with a reference count of 0 are cached according to LRU rules

Member Typedef Documentation

CacheIter

template<typename K , typename T >

typedef std::list<Node<K,T>>::iterator aurore::LRUCache< K, T >::CacheIter

Constructor & Destructor Documentation

LRUCache()

template<typename K , typename T >

aurore::LRUCache< K, T >::LRUCache ( size_t  c, T  defaultValue  )

inline

Member Function Documentation

debug()

template<typename K , typename T >

void aurore::LRUCache< K, T >::debug ( )

inline

get()

template<typename K , typename T >

T aurore::LRUCache< K, T >::get ( K  key )

inline

getCacheList()

template<typename K , typename T >

std::list< Node< K, T > > & aurore::LRUCache< K, T >::getCacheList ( )

inline

getSize()

template<typename K , typename T >

size_t aurore::LRUCache< K, T >::getSize ( ) const

inline

getTotalBytes()

template<typename K , typename T >

size_t aurore::LRUCache< K, T >::getTotalBytes ( ) const

inline

markAllDirty()

template<typename K , typename T >

void aurore::LRUCache< K, T >::markAllDirty ( )

inline

markDirty()

template<typename K , typename T >

void aurore::LRUCache< K, T >::markDirty ( T  value )

inline

A dirty cache is not able to be hit

Parameters

value

remove()

template<typename K , typename T >

void aurore::LRUCache< K, T >::remove ( T  value )

inline

It is not really to remove a cache, but to reduce the counter of the corresponding cache by 1

set()

template<typename K , typename T >

void aurore::LRUCache< K, T >::set ( K  key, T  value  )

inline

setCapacity()

template<typename K , typename T >

void aurore::LRUCache< K, T >::setCapacity ( int  c )

inline

setMemoryBudget()

template<typename K , typename T >

void aurore::LRUCache< K, T >::setMemoryBudget ( size_t  bytes, std::function< size_t(T)>  sizeOf  )

inline

A budget in bytes, on top of the capacity in entries (0: none). Over it, the least recently used entries nothing holds are freed. sizeOf says what an entry weighs.

trimUnused()

template<typename K , typename T >

void aurore::LRUCache< K, T >::trimUnused ( )

inline

Delete all cache entries whose reference count has dropped to zero. Call this after releasing images to promptly free GPU memory.

update()

template<typename K , typename T >

void aurore::LRUCache< K, T >::update ( T  old_val, T  new_val  )

inline

Update a cache value
