# reInterval

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.
