cache2

A cache implementation in Go

This is used in uniqush-push

Because some installations of uniqush-push predate versioned dependencies, this was created as a repo separate from uniqush/cache, because of the inconvenience caused by interface incompatibilities.

Types

type Cache

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

func New

func New(capacity int, maxNrDirty int, flushPeriod time.Duration, flusher Flusher) *Cache

capacity: nr elements in the cache. capacity < 0 means always in memory; capacity = 0 means no cache.

maxNrDirty: < 0 means no flush.

flushPeriod: flushPeriod > 1 second means periodically flush; flushPeriod = 0 second means no periodically flush; undefined in range (0, 1).
