Types ¶
type GfCache ¶ added in v0.0.3
type GfCache struct {
CachePrefix string //缓存前缀
// contains filtered or unexported fields
}
func (*GfCache) Contains ¶ added in v0.0.3
Contains returns true if <tagKey> exists in the cache, or else returns false.
func (*GfCache) Data ¶ added in v0.0.3
Data returns a copy of all tagKey-value pairs in the cache as map type.
func (*GfCache) Get ¶ added in v0.0.3
Get returns the value of <tagKey>. It returns nil if it does not exist or its value is nil.
func (*GfCache) GetOrSet ¶ added in v0.0.3
func (c *GfCache) GetOrSet(ctx context.Context, key string, value interface{}, duration time.Duration, tag string) *gvar.Var
GetOrSet returns the value of <tagKey>, or sets <tagKey>-<value> pair and returns <value> if <tagKey> does not exist in the cache. The tagKey-value pair expires after <duration>.
It does not expire if <duration> <= 0.
func (*GfCache) GetOrSetFunc ¶ added in v0.0.3
func (c *GfCache) GetOrSetFunc(ctx context.Context, key string, f gcache.Func, duration time.Duration, tag string) *gvar.Var
GetOrSetFunc returns the value of <tagKey>, or sets <tagKey> with result of function <f> and returns its result if <tagKey> does not exist in the cache. The tagKey-value pair expires after <duration>. It does not expire if <duration> <= 0.
func (*GfCache) GetOrSetFuncLock ¶ added in v0.0.3
func (c *GfCache) GetOrSetFuncLock(ctx context.Context, key string, f gcache.Func, duration time.Duration, tag string) *gvar.Var
GetOrSetFuncLock returns the value of <tagKey>, or sets <tagKey> with result of function <f> and returns its result if <tagKey> does not exist in the cache. The tagKey-value pair expires after <duration>. It does not expire if <duration> <= 0.
Note that the function <f> is executed within writing mutex lock.
func (*GfCache) KeyStrings ¶ added in v0.0.3
KeyStrings returns all keys in the cache as string slice.
func (*GfCache) Remove ¶ added in v0.0.3
Remove deletes the <tagKey> in the cache, and returns its value.
func (*GfCache) RemoveByTag ¶ added in v0.0.3
RemoveByTag deletes the <tag> in the cache, and returns its value.
func (*GfCache) RemoveByTags ¶ added in v0.0.3
RemoveByTags deletes <tags> in the cache.
func (*GfCache) Set ¶ added in v0.0.3
func (c *GfCache) Set(ctx context.Context, key string, value interface{}, duration time.Duration, tag ...string)
Set sets cache with <tagKey>-<value> pair, which is expired after <duration>. It does not expire if <duration> <= 0.
func (*GfCache) SetIfNotExist ¶ added in v0.0.3
func (c *GfCache) SetIfNotExist(ctx context.Context, key string, value interface{}, duration time.Duration, tag string) bool
SetIfNotExist sets cache with <tagKey>-<value> pair if <tagKey> does not exist in the cache, which is expired after <duration>. It does not expire if <duration> <= 0.
type IGCache ¶ added in v0.0.3
type IGCache interface {
Get(ctx context.Context, key string) *gvar.Var
Set(ctx context.Context, key string, value interface{}, duration time.Duration, tag ...string)
Remove(ctx context.Context, key string) *gvar.Var
Removes(ctx context.Context, keys []string)
RemoveByTag(ctx context.Context, tag string)
RemoveByTags(ctx context.Context, tag []string)
SetIfNotExist(ctx context.Context, key string, value interface{}, duration time.Duration, tag string) bool
GetOrSet(ctx context.Context, key string, value interface{}, duration time.Duration, tag string) *gvar.Var
GetOrSetFunc(ctx context.Context, key string, f gcache.Func, duration time.Duration, tag string) *gvar.Var
GetOrSetFuncLock(ctx context.Context, key string, f gcache.Func, duration time.Duration, tag string) *gvar.Var
Contains(ctx context.Context, key string) bool
Data(ctx context.Context) map[interface{}]interface{}
Keys(ctx context.Context) []interface{}
KeyStrings(ctx context.Context) []string
Values(ctx context.Context) []interface{}
Size(ctx context.Context) int
}
