README

package cache

package cache is bytes/interface cache manager.

Usage:

import "github.com/hetianyi/gox/cache"
// apply cache
bc := cache.ApplyBytes(bufferSize, false)
// recache
defer cache.ReCacheBytes(bc)
// use cache...

Functions

func ApplyResource

func ApplyResource(p reflect.Type, fallback func() interface{}) interface{}

ApplyResource applies specified type of resource which cached before.

func ReCacheBytes

func ReCacheBytes(bc ByteCapsule)

ReCacheBytes caches bytes ByteCapsule

func ReCacheResource

func ReCacheResource(res interface{})

ReCacheResource caches bytes ByteCapsule

func SetCacheBytesListSize

func SetCacheBytesListSize(size int)

SetCacheBytesListSize sets max size of each cache list.

func SetCacheResourceListSize

Types

type ByteCapsule

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

ByteCapsule is small bytes container

func ApplyBytes

func ApplyBytes(size int, dynamic bool) ByteCapsule

ApplyBytes applies specified size of bytes array. dynamic bytes apply will not be cached

func (*ByteCapsule) Bytes

func (bc *ByteCapsule) Bytes() []byte

Bytes returns bytes array of ByteCapsule
