# resync
|
||
|
|
|
||
|
|
`sync.Once` with `Reset()`
|
||
|
|
|
||
|
|
* See [sync.Once](http://golang.org/pkg/sync/#Once)
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
The following example examines how `resync.Once` could be used in a HTTP server situation.
|
||
|
|
|
||
|
|
```
|
||
|
|
// use it just like sync.Once
|
||
|
|
var once resync.Once
|
||
|
|
|
||
|
|
// handle a web request
|
||
|
|
func handleRequest(w http.ResponseWriter, r *http.Request) {
|
||
|
|
once.Do(func(){
|
||
|
|
// load templates or something
|
||
|
|
})
|
||
|
|
// TODO: respond
|
||
|
|
}
|
||
|
|
|
||
|
|
// handle some request that indicates things have changed
|
||
|
|
func handleResetRequest(w http.ResponseWriter, r *http.Request) {
|
||
|
|
once.Reset() // call Reset to cause initialisation to happen again above
|
||
|
|
}
|
||
|
|
```
