Reschedulable setInterval for node.js.
|
|
|
|
###### Note: Work highly inspired by [mcollina](https://github.com/mcollina)'s [retimer](https://github.com/mcollina/retimer).
|
|
|
|
## Example
|
|
|
|
```js
|
|
var reInterval = require('reInterval');
|
|
|
|
var inter = reInterval(function () {
|
|
console.log('this should be called after 13s');
|
|
}, 10 * 1000);
|
|
|
|
// This will reset/reschedule the interval after 3 seconds, therefore
|
|
// the interval callback won't be called for at least 13 seconds.
|
|
setTimeout(function () {
|
|
inter.reschedule(10 * 1000);
|
|
}, 3 * 1000);
|
|
```
|
|
|
|
|
|
## API:
|
|
|
|
###`reInterval(callback, interval[, param1, param2, ...])`
|
|
|
|
This is exactly like setInterval.
|
|
|
|
_Arguments:_
|
|
- `callback`: The callback to be executed repeatedly.
|
|
- `interval`: The number of milliseconds (thousandths of a second) that the `reInterval()` function should wait before each call to `callback`.
|
|
- `param1, param2, ...`: *(OPTIONAL)* These arguments are passed to the `callback` function.
|
|
|
|
####returns an `interval` object with the following methods:
|
|
|
|
###`interval.reschedule([interval])`
|
|
|
|
This function resets the `interval` and restarts it now.
|
|
|
|
_Arguments:_
|
|
- `interval`: *(OPTIONAL)* This argument can be used to change the amount of milliseconds to wait before each call to the `callback` passed to the `reInterval()` function.
|
|
|
|
###`interval.clear()`
|
|
|
|
This function clears the interval. Can be used to temporarily clear the `interval`, which can be rescheduled at a later time.
|
|
|
|
###`interval.destroy()`
|
|
|
|
This function clears the interval, and will also clear the `callback` and `params` passed to reInterval, so calling this essentially just makes this object ready for overwriting with a new `interval` object.
|
|
|
|
#### Note:
|
|
Please ensure that either the `interval.clear()` or `interval.destroy()` function is called before overwriting the `interval` object, because the internal `interval` can continue to run in the background unless cleared.
