Types ¶
type Persister ¶
type Persister struct {
State *state.State
Memory *cache.Cache
// contains filtered or unexported fields
}
Persister abstracts storage and retrieval of state and cache.
func NewPersister ¶
NewPersister creates a new Persister instance.
func (*Persister) Deserialize ¶
Deserialize decodes the state and cache from storage, and applies them to the persister.
func (*Persister) GetMemory ¶
GetMemory returns the cache (memory) enclosed by the Persister.
func (*Persister) GetState ¶
GetState returns the state enclosed by the Persister.
func (*Persister) Invalid ¶
Invalid checks if the underlying state has been invalidated.
An invalid state will cause Save to panic.
func (*Persister) Load ¶
Load retrieves state and cache from the db.Db backend.
func (*Persister) Save ¶
Save perists the state and cache to the db.Db backend.
func (*Persister) Serialize ¶
Serialize encodes the state and cache into byte form for storage.
func (*Persister) WithContent ¶
WithContent sets a current State and Cache object.
This method is normally called before Serialize / Save.
func (*Persister) WithContext ¶
WithSession is a chainable function that sets the current golang context of the persister.
