SimpleTTL

Simple TTL on golang for map[string]interface{}, so keys is string and values is something.

See more detail: https://en.wikipedia.org/wiki/Time_to_live

Minimal example of using:

func main(){
	cache := simplettl.NewCache(2 * time.Second)
	key := "foo"
	value := "bar"
	cache.Add(key, value, time.Second)
	if r, ok := cache.Get(key); ok {
		fmt.Printf("Value for key %v is %v",key,r)
	}
}

Types

type Cache

type Cache struct {
	// contains filtered or unexported fields
}

Cache - simple implementation of cache More information: https://en.wikipedia.org/wiki/Time_to_live

func NewCache

func NewCache(interval time.Duration) *Cache

NewCache - initialization of new cache. For avoid mistake - minimal time to live is 1 minute. For simplification, - key is string and cache haven`t stop method

Example

cache := simplettl.NewCache(2 * time.Second)
key := "foo"
value := "bar"
cache.Add(key, value, time.Second)
if r, ok := cache.Get(key); ok {
	fmt.Printf("Value for key %v is %v", key, r)
}

Output:

Value for key foo is bar

func (*Cache) Add

func (cache *Cache) Add(key string, value interface{}, ttl time.Duration)

Add - add key/value in cache

func (*Cache) Count

func (cache *Cache) Count() int

Count - return amount element of TTL map.

func (*Cache) Get

func (cache *Cache) Get(key string) (interface{}, bool)

Get - return value from cache

func (*Cache) GetKeys

func (cache *Cache) GetKeys() []interface{}

GetKeys - return all keys of cache map
