New creates an LRU of the given size.

func NewWithEvictionFunc ¶

func NewWithEvictionFunc(size int, f EvictionFunc) *Cache

NewWithEvictionFunc creates an LRU of the given size with the given eviction func.

func (*Cache) Add ¶

func (c *Cache) Add(key Key, value interface{})

Add adds a value to the cache.

func (*Cache) Clear ¶

func (c *Cache) Clear()

Clear purges all stored items from the cache.

func (*Cache) Get ¶

func (c *Cache) Get(key Key) (value interface{}, ok bool)

Remove removes the provided key from the cache.

func (*Cache) RemoveOldest ¶

func (c *Cache) RemoveOldest()

RemoveOldest removes the oldest item from the cache.

func (*Cache) SetEvictionFunc ¶

func (c *Cache) SetEvictionFunc(f EvictionFunc) error
