概述
我们知道,Go 语言已经提供了 sync.Pool
,但是做的不怎么好,所以有必要来实现一个 Pool
代码
type Pool struct {
pool chan *Client
}
// Create a new Pool
func NewPool(max int) *Pool{
return &Pool{
pool: make(chan *Client, max)
}
}
// Get a Client from Pool
func (p *Pool) Borrow() *Client {
var cl *Client
select {
case cl = <-p.pool:
default:
c1 = newClient()
}
return cl
}
// Return the Cliet to the pool
func (p *Pool) Return(cl *Client){
select {
case p.pool<- cl:
default:
// let it go, let it go....
}
}
现在是 Golang1.4了,sync.Pool
还是不可以用吗?
