Types ¶

type Cache ¶

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

Cache is a struct in which the cache's methods synchronize access to this map, so it is not recommended to keep any references to the map around after creating a cache.

func NewCacheService ¶

func NewCacheService(defaultExpiration, cleanupInterval time.Duration) *Cache

NewCacheService is used to initialize a new cache. Return a new cache with a given default expiration duration and cleanup interval. If the expiration duration is less than one, the items in the cache never expire (by default), and must be deleted manually. If the cleanup interval is less than one, expired items are not deleted from the cache before calling c.deleteExpired().

func (Cache) Add ¶

func (c Cache) Add(ctx context.Context, item *api.Item) (*api.Item, error)

Add is used to add key/value pair to the cache.

func (Cache) DeleteAll ¶

func (c Cache) DeleteAll(ctx context.Context, in *empty.Empty) (*api.Success, error)

Delete all items from the cache.

func (Cache) DeleteKey ¶

func (c Cache) DeleteKey(ctx context.Context, args *api.GetKey) (*api.Success, error)

DeleteKey deletes an item from the cache. Does nothing if the key is not in the cache.

func (Cache) Get ¶

func (c Cache) Get(ctx context.Context, args *api.GetKey) (*api.Item, error)

Get method is used to key/value pair while providing key as args

func (Cache) GetAllItems ¶

func (c Cache) GetAllItems(ctx context.Context, in *empty.Empty) (*api.AllItems, error)

GetAllItems method get all unexpired keys from the cache

func (Cache) GetByPrefix ¶

func (c Cache) GetByPrefix(ctx context.Context, args *api.GetKey) (*api.AllItems, error)

	Expiration int64
}

Item items value of key and expiration
