    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

<!-- Package usage documentation. -->

<section class="installation">

## Installation

```bash
npm install @stdlib/slice-multi
```

</section>

<section class="usage">

## Usage

```javascript
var MultiSlice = require( '@stdlib/slice-multi' );
```

<a name="main"></a>

#### MultiSlice( ...slice )

Returns a `MultiSlice` instance.

```javascript
var Slice = require( '@stdlib/slice-ctor' );

var s = new Slice( 0, 10 );
// returns <Slice>

var ms = new MultiSlice( 2, s, null );
// returns <MultiSlice>
```

The constructor accepts the following arguments:

-   **slice**: a single-dimensional slice. May be either a [`Slice`][@stdlib/slice/ctor], `null`, `undefined`, or an integer.

* * *

### Properties

<a name="static-prop-name"></a>

#### MultiSlice.name

String value of the `MultiSlice` constructor name.

```javascript
var str = MultiSlice.name;
// returns 'MultiSlice'
```

<a name="prop-ndims"></a>

#### MultiSlice.prototype.ndims

**Read-only** property returning the number of slice dimensions.

```javascript
var Slice = require( '@stdlib/slice-ctor' );

var s = new Slice( 0, 10 );
// returns <Slice>

var ms = new MultiSlice( 2, s, null );
// returns <MultiSlice>

var ndims = ms.ndims;
// returns 3
```

<a name="prop-data"></a>

#### MultiSlice.prototype.data

**Read-only** property returning the slice data.

```javascript
var Slice = require( '@stdlib/slice-ctor' );

var s = new Slice( 0, 10 );
// returns <Slice>

var ms = new MultiSlice( 2, s, null );
// returns <MultiSlice>

var data = ms.data;
// returns [ 2, <Slice>, null ]
```

* * *

### Methods

<a name="method-to-string"></a>

#### MultiSlice.prototype.toString()

Serializes a `MultiSlice` as a string.

```javascript
var Slice = require( '@stdlib/slice-ctor' );

var s = new Slice( 10 );
// returns <Slice>

var ms = new MultiSlice( 2, s, null );
// returns <MultiSlice>

var str = ms.toString();
// returns 'MultiSlice(2,Slice(null,10,null),null)'
```

<a name="method-to-json"></a>

#### MultiSlice.prototype.toJSON()

Serializes a `MultiSlice` as a [JSON][json] object.

```javascript
var Slice = require( '@stdlib/slice-ctor' );

var s = new Slice( 10 );
// returns <Slice>

var ms = new MultiSlice( 2, s, null );
// returns <MultiSlice>

var o = ms.toJSON();
// returns { 'type': 'MultiSlice', 'data': [ 2, { 'type': 'Slice', 'data': [ null, 10, null ] }, null ] }
```

`JSON.stringify()` implicitly calls this method when stringifying a `MultiSlice` instance.

<section class="notes">

## Notes

-   Slice arguments may be either integers, `null`, or `undefined`, where a non-integer value indicates a slice parameter which should be determined based on the slice context (e.g., when used to index into an [`ndarray`][@stdlib/ndarray/ctor]).
-   Multi-slice instances have no explicit functionality; however, they are used by [`ndarray`][@stdlib/ndarray] and other packages for creating views into multi-dimensional data structures.

## Examples

<!-- eslint no-undef: "error" -->

<!-- eslint-disable new-cap -->

```javascript
var S = require( '@stdlib/slice-ctor' );
var MultiSlice = require( '@stdlib/slice-multi' );

// Alias `undefined` for more concise expressions:
var _ = void 0;

// Create a 6-dimensional slice:
var s = new MultiSlice( S( 9, -10, -1 ), S( 2, _, 2 ), 2, S( 5, _, 2 ), 3, _ );
// returns <MultiSlice>

// Serialize the slice to a string:
var str = s.toString();
console.log( str );
// => 'MultiSlice(Slice(9,-10,-1),Slice(2,null,2),2,Slice(5,null,2),3,null)'

// Serialize the slice to JSON:
var o = s.toJSON();
console.log( JSON.stringify( o ) );
// => '{"type":"MultiSlice","data":[{"type":"Slice","data":[9,-10,-1]},{"type":"Slice","data":[2,null,2]},2,{"type":"Slice","data":[5,null,2]},3,null]}'
```
