Types ¶
type WTinyLFUCache ¶
type WTinyLFUCache[K comparable, V any] struct { // contains filtered or unexported fields }
WTinyLFUCache is a Windowed TinyLFU cache implementation. It uses a window cache (1%) and SLRU main cache (99%) with frequency-based admission policy.
func NewWTinyLFUCache ¶
func NewWTinyLFUCache[K comparable, V any](capacity int) *WTinyLFUCache[K, V]
NewWTinyLFUCache creates a new Windowed TinyLFU cache with the specified capacity. The cache uses a window cache (1%) and SLRU main cache (99%) with frequency-based admission.
func NewWTinyLFUCacheWithEvictionCallback ¶
func NewWTinyLFUCacheWithEvictionCallback[K comparable, V any](capacity int, onEviction base.EvictionCallback[K, V]) *WTinyLFUCache[K, V]
NewWTinyLFUCacheWithEvictionCallback creates a new Windowed TinyLFU cache with the specified capacity and eviction callback.
func (*WTinyLFUCache[K, V]) Algorithm ¶
func (c *WTinyLFUCache[K, V]) Algorithm() string
Algorithm returns the name of the eviction algorithm used by the cache.
func (*WTinyLFUCache[K, V]) All ¶
func (c *WTinyLFUCache[K, V]) All() map[K]V
All returns all key-value pairs in the cache.
func (*WTinyLFUCache[K, V]) Capacity ¶
func (c *WTinyLFUCache[K, V]) Capacity() int
Capacity returns the maximum number of items the cache can hold.
func (*WTinyLFUCache[K, V]) Delete ¶
func (c *WTinyLFUCache[K, V]) Delete(key K) bool
Delete removes a key from the cache.
func (*WTinyLFUCache[K, V]) DeleteMany ¶
func (c *WTinyLFUCache[K, V]) DeleteMany(keys []K) map[K]bool
DeleteMany removes multiple keys from the cache.
func (*WTinyLFUCache[K, V]) Get ¶
func (c *WTinyLFUCache[K, V]) Get(key K) (value V, ok bool)
Get retrieves a value from the cache.
func (*WTinyLFUCache[K, V]) GetMany ¶
func (c *WTinyLFUCache[K, V]) GetMany(keys []K) (map[K]V, []K)
GetMany retrieves multiple values from the cache.
func (*WTinyLFUCache[K, V]) Has ¶
func (c *WTinyLFUCache[K, V]) Has(key K) bool
Has checks if a key exists in the cache.
func (*WTinyLFUCache[K, V]) HasMany ¶
func (c *WTinyLFUCache[K, V]) HasMany(keys []K) map[K]bool
HasMany checks if multiple keys exist in the cache.
func (*WTinyLFUCache[K, V]) Keys ¶
func (c *WTinyLFUCache[K, V]) Keys() []K
Keys returns all keys currently in the cache.
func (*WTinyLFUCache[K, V]) Len ¶
func (c *WTinyLFUCache[K, V]) Len() int
Len returns the current number of items in the cache.
func (*WTinyLFUCache[K, V]) Peek ¶
func (c *WTinyLFUCache[K, V]) Peek(key K) (value V, ok bool)
Peek retrieves a value from the cache without updating access order.
func (*WTinyLFUCache[K, V]) PeekMany ¶
func (c *WTinyLFUCache[K, V]) PeekMany(keys []K) (map[K]V, []K)
PeekMany retrieves multiple values from the cache without updating access order.
func (*WTinyLFUCache[K, V]) Purge ¶
func (c *WTinyLFUCache[K, V]) Purge()
Purge removes all keys and values from the cache.
func (*WTinyLFUCache[K, V]) Range ¶
func (c *WTinyLFUCache[K, V]) Range(f func(K, V) bool)
Range iterates over all key-value pairs in the cache.
func (*WTinyLFUCache[K, V]) Set ¶
func (c *WTinyLFUCache[K, V]) Set(key K, value V)
Set stores a key-value pair in the cache.
func (*WTinyLFUCache[K, V]) SetMany ¶
func (c *WTinyLFUCache[K, V]) SetMany(items map[K]V)
SetMany stores multiple key-value pairs in the cache.
func (*WTinyLFUCache[K, V]) SizeBytes ¶
func (c *WTinyLFUCache[K, V]) SizeBytes() int64
SizeBytes returns the total size of all cache entries in bytes.
func (*WTinyLFUCache[K, V]) Values ¶
func (c *WTinyLFUCache[K, V]) Values() []V
Values returns all values currently in the cache.
