Types

type Cache

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

func New

func New(cleaningInterval time.Duration) *Cache

New creates a new cache that asynchronously cleans expired entries after the given time passes.

func OnGetCache

func OnGetCache(cachename string) *Cache

初始化一个cache cachename 缓存名字

func (*Cache) Add

func (c *Cache) Add(key interface{}, value interface{}, lifeSpan time.Duration)

添加一个缓存 lifeSpan:缓存时间，0表示永不超时

func (*Cache) Clear

func (c *Cache) Clear() bool

清空表內容

func (*Cache) Close

func (cache *Cache) Close()

Close closes the cache and frees up resources.

func (*Cache) Delete

func (cache *Cache) Delete(key interface{})

Delete deletes the key and its value from the cache.

func (*Cache) Get

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

Get gets the value for the given key.

func (*Cache) IsExist

func (c *Cache) IsExist(key interface{}) bool

判断key是否存在

func (*Cache) Range

func (cache *Cache) Range(f func(key, value interface{}) bool)

Range calls f sequentially for each key and value present in the cache. If f returns false, range stops the iteration.

func (*Cache) Set

func (cache *Cache) Set(key interface{}, value interface{}, duration time.Duration)

Set sets a value for the given key with an expiration duration. If the duration is 0 or less, it will be stored forever.

func (*Cache) Value

func (c *Cache) Value(key interface{}) (interface{}, bool)

type MyCache

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