node_modules/denque/CHANGELOG.md
View file @ b807a4c1
## 2.0.1
- fix(types): incorrect return type on `size()`
## 2.0.0
- fix!: `push` & `unshift` now accept `undefined` values to match behaviour of `Array` (fixes #25) (#35)
- This is only a **BREAKING** change if you are currently expecting `push(undefined)` and `unshift(undefined)` to do
nothing - the new behaviour now correctly adds undefined values to the queue.
- **Note**: behaviour of `push()` & `unshift()` (no arguments) remains unchanged (nothing gets added to the queue).
- **Note**: If you need to differentiate between `undefined` values in the queue and the return value of `pop()` then
check the queue `.length` before popping.
- fix: incorrect methods in types definition file
## 1.5.1
- perf: minor performance tweak when growing queue size (#29)
## 1.5.0
- feat: adds capacity option for circular buffers (#27)

Extremely fast and lightweight [double-ended queue](http://en.wikipedia.org/wiki/Double-ended_queue) implementation with zero dependencies.
Denque is a well tested, extremely fast and lightweight [double-ended queue](http://en.wikipedia.org/wiki/Double-ended_queue)
implementation with zero dependencies and includes TypeScript types.
Double-ended queues can also be used as a:
- [Stack](http://en.wikipedia.org/wiki/Stack_\(abstract_data_type\))
- [Queue](http://en.wikipedia.org/wiki/Queue_\(data_structure\))
This implementation is currently the fastest available, even faster than `double-ended-queue`, see the [benchmarks](#benchmarks)
This implementation is currently the fastest available, even faster than `double-ended-queue`, see the [benchmarks](https://docs.page/invertase/denque/benchmarks).
Every queue operation is done at a constant `O(1)` - including random access from `.peekAt(index)`.
**Works on all node versions >= v0.10**
# Quick Start
## Quick Start
npm install denque
Install the package:
```js
const Denque = require("denque");
const denque = new Denque([1,2,3,4]);
denque.shift(); // 1
denque.pop(); // 4
```bash
npm install denque
```

#### `new Denque()` -> `Denque`
Creates an empty double-ended queue with initial capacity of 4.
Create and consume a queue:
```js
var denque = new Denque();
denque.push(1);
denque.push(2);
denque.push(3);
denque.shift(); //1
denque.pop(); //3
```
<hr>
#### `new Denque(Array items)` -> `Denque`
Creates a double-ended queue from `items`.
const Denque = require("denque");
```js
var denque = new Denque([1,2,3,4]);
const denque = new Denque([1,2,3,4]);
denque.shift(); // 1
denque.pop(); // 4
```
<hr>
#### `push(item)` -> `int`
Push an item to the back of this queue. Returns the amount of items currently in the queue after the operation.
```js
var denque = new Denque();
denque.push(1);
denque.pop(); // 1
denque.push(2);
denque.push(3);
denque.shift(); // 2
denque.shift(); // 3
```
<hr>
#### `unshift(item)` -> `int`
Unshift an item to the front of this queue. Returns the amount of items currently in the queue after the operation.
```js
var denque = new Denque([2,3]);
denque.unshift(1);
denque.toString(); // "1,2,3"
denque.unshift(-2);
denque.toString(); // "-2,-1,0,1,2,3"
```
<hr>
#### `pop()` -> `dynamic`
Pop off the item at the back of this queue.
Note: The item will be removed from the queue. If you simply want to see what's at the back of the queue use [`peekBack()`](#peekback---dynamic) or [`.peekAt(-1)`](#peekAtint-index---dynamic).
If the queue is empty, `undefined` is returned. If you need to differentiate between `undefined` values in the queue and `pop()` return value -
check the queue `.length` before popping.
```js
var denque = new Denque([1,2,3]);
denque.pop(); // 3
denque.pop(); // 2
denque.pop(); // 1
denque.pop(); // undefined
```
**Aliases:** `removeBack`
<hr>
#### `shift()` -> `dynamic`
Shifts off the item at the front of this queue.
Note: The item will be removed from the queue. If you simply want to see what's at the front of the queue use [`peekFront()`](#peekfront---dynamic) or [`.peekAt(0)`](#peekAtint-index---dynamic).
If the queue is empty, `undefined` is returned. If you need to differentiate between `undefined` values in the queue and `shift()` return value -
check the queue `.length` before shifting.
```js
var denque = new Denque([1,2,3]);
denque.shift(); // 1
denque.shift(); // 2
denque.shift(); // 3
denque.shift(); // undefined
```
<hr>
#### `toArray()` -> `Array`
Returns the items in the queue as an array. Starting from the item in the front of the queue and ending to the item at the back of the queue.
```js
var denque = new Denque([1,2,3]);
denque.push(4);
denque.unshift(0);
denque.toArray(); // [0,1,2,3,4]
```
<hr>
#### `peekBack()` -> `dynamic`
Returns the item that is at the back of this queue without removing it.
If the queue is empty, `undefined` is returned.
```js
var denque = new Denque([1,2,3]);
denque.push(4);
denque.peekBack(); // 4
```
<hr>
#### `peekFront()` -> `dynamic`
Returns the item that is at the front of this queue without removing it.
If the queue is empty, `undefined` is returned.
```js
var denque = new Denque([1,2,3]);
denque.push(4);
denque.peekFront(); // 1
```
<hr>
#### `peekAt(int index)` -> `dynamic`
Returns the item that is at the given `index` of this queue without removing it.
The index is zero-based, so `.peekAt(0)` will return the item that is at the front, `.peekAt(1)` will return
the item that comes after and so on.
The index can be negative to read items at the back of the queue. `.peekAt(-1)` returns the item that is at the back of the queue,
`.peekAt(-2)` will return the item that comes before and so on.
Returns `undefined` if `index` is not a valid index into the queue.
```js
var denque = new Denque([1,2,3]);
denque.peekAt(0); //1
denque.peekAt(1); //2
denque.peekAt(2); //3
denque.peekAt(-1); // 3
denque.peekAt(-2); // 2
denque.peekAt(-3); // 1
```
**Note**: The implementation has O(1) random access using `.peekAt()`.
**Aliases:** `get`
<hr>
#### `remove(int index, int count)` -> `array`
Remove number of items from the specified index from the list.
Returns array of removed items.
Returns undefined if the list is empty.
```js
var denque = new Denque([1,2,3,4,5,6,7]);
denque.remove(0,3); //[1,2,3]
denque.remove(1,2); //[5,6]
var denque1 = new Denque([1,2,3,4,5,6,7]);
denque1.remove(4, 100); //[5,6,7]
```
<hr>
#### `removeOne(int index)` -> `dynamic`
Remove and return the item at the specified index from the list.
Returns undefined if the list is empty.
```js
var denque = new Denque([1,2,3,4,5,6,7]);
denque.removeOne(4); // 5
denque.removeOne(3); // 4
denque1.removeOne(1); // 2
```
<hr>
#### `splice(int index, int count, item1, item2, ...)` -> `array`
Native splice implementation.
Remove number of items from the specified index from the list and/or add new elements.
Returns array of removed items or empty array if count == 0.
Returns undefined if the list is empty.
See the [API reference documentation](https://docs.page/invertase/denque/api) for more examples.
```js
var denque = new Denque([1,2,3,4,5,6,7]);
denque.splice(denque.length, 0, 8, 9, 10); // []
denque.toArray() // [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]
denque.splice(3, 3, 44, 55, 66); // [4,5,6]
denque.splice(5,4, 666,667,668,669); // [ 66, 7, 8, 9 ]
denque.toArray() // [ 1, 2, 3, 44, 55, 666, 667, 668, 669, 10 ]
```
<hr>
#### `isEmpty()` -> `boolean`
Return `true` if this queue is empty, `false` otherwise.
```js
var denque = new Denque();
denque.isEmpty(); // true
denque.push(1);
denque.isEmpty(); // false
```
<hr>
#### `clear()` -> `void`
Remove all items from this queue. Does not change the queue's capacity.
```js
var denque = new Denque([1,2,3]);
denque.toString(); // "1,2,3"
denque.clear();
denque.toString(); // ""
```
<hr>

### destroy(stream)
### destroy(stream [, suppress])
Destroy the given stream. In most cases, this is identical to a simple
`stream.destroy()` call. The rules are as follows for a given stream:
Destroy the given stream, and optionally suppress any future `error` events.
In most cases, this is identical to a simple `stream.destroy()` call. The rules
are as follows for a given stream:
1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
and add a listener to the `open` event to call `stream.close()` if it is
fired. This is for a Node.js bug that will leak a file descriptor if
`.destroy()` is called before `open`.
2. If the `stream` is not an instance of `Stream`, then nothing happens.
3. If the `stream` has a `.destroy()` method, then call it.
2. If the `stream` is an instance of a zlib stream, then call `stream.destroy()`
and close the underlying zlib handle if open, otherwise call `stream.close()`.
This is for consistency across Node.js versions and a Node.js bug that will
leak a native zlib handle.
3. If the `stream` is not an instance of `Stream`, then nothing happens.
4. If the `stream` has a `.destroy()` method, then call it.
The function returns the `stream` passed in as the argument.
