Types ¶
type Cache ¶
type Cache struct {
// MaxEntries is the maximum number of cache entries before
// an item is evicted. Zero means no limit.
MaxEntries int
// OnEvicted optionally specifies a callback function to be
// executed when an entry is purged from the cache.
OnEvicted func(key Key, value interface{})
// contains filtered or unexported fields
}
Cache is an LRU cache. It is not safe for concurrent access.
func New ¶
New creates a new Cache. If maxEntries is zero, the cache has no limit and it's assumed that eviction is done by the caller.
func (*Cache) GetAndRemoveExpire ¶
GetAndRemoveExpire loos up a key's value ,returns if it exists and call a defer func to check it whether it's expired or not. If it was expired,remove it
func (*Cache) RemoveExpire ¶
func (c *Cache) RemoveExpire()
func (*Cache) RemoveOldest ¶
func (c *Cache) RemoveOldest()
RemoveOldest removes the oldest item from the cache.
type Key ¶
type Key interface{}
A Key may be any value that is comparable. See http://golang.org/ref/spec#Comparison_operators
