Types

type Cache

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

Cache holds an internal linkedlist for hotness management. It is not safe for concurrent use, must be guarded externally.

func New

func New(maxentries int) *Cache

New returns a route cache.

func (*Cache) Delete

func (c *Cache) Delete(appname, path string)

Delete removes the element for the given appname and path from the cache.

func (*Cache) Get

func (c *Cache) Get(appname, path string) (route *models.Route, ok bool)

Get looks up a path's route from the cache.

func (*Cache) Len

func (c *Cache) Len() int

func (*Cache) Refresh

func (c *Cache) Refresh(route *models.Route)

Refresh updates internal linkedlist either adding a new route to the front, or moving it to the front when used. It will discard seldom used routes.
