Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer).

This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream. - -Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object. - -`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with: - -```js -var bl = require('bl') -var myinstance = bl() - -// equivalent to: - -var BufferList = require('bl') -var myinstance = new BufferList() -``` - --------------------------------------------------------- -<a name="length"></a> -### bl.length -Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list. - --------------------------------------------------------- -<a name="append"></a> -### bl.append(Buffer | Buffer array | BufferList | BufferList array | String) -`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained. - --------------------------------------------------------- -<a name="get"></a> -### bl.get(index) -`get()` will return the byte at the specified index. - --------------------------------------------------------- -<a name="indexOf"></a> -### bl.indexOf(value[, byteOffset][, encoding]) -`get()` will return the byte at the specified index. -`indexOf()` method returns the first index at which a given element can be found in the BufferList, or -1 if it is not present. - --------------------------------------------------------- -<a name="slice"></a> -### bl.slice([ start, [ end ] ]) -`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively. - -If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer. - --------------------------------------------------------- -<a name="shallowSlice"></a> -### bl.shallowSlice([ start, [ end ] ]) -`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively. - -No copies will be performed. All buffers in the result share memory with the original list. - --------------------------------------------------------- -<a name="copy"></a> -### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ]) -`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively. - --------------------------------------------------------- -<a name="duplicate"></a> -### bl.duplicate() -`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example: - -```js -var bl = new BufferList() - -bl.append('hello') -bl.append(' world') -bl.append('\n') - -bl.duplicate().pipe(process.stdout, { end: false }) - -console.log(bl.toString()) -``` - --------------------------------------------------------- -<a name="consume"></a> -### bl.consume(bytes) -`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers—initial offsets will be calculated accordingly in order to give you a consistent view of the data. - --------------------------------------------------------- -<a name="toString"></a> -### bl.toString([encoding, [ start, [ end ]]]) -`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information. - --------------------------------------------------------- -<a name="readXX"></a> -### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8() - -All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently. - -See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work. - --------------------------------------------------------- -<a name="streams"></a> -### Streams -**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **bl** instance. - --------------------------------------------------------- - -## Contributors - -**bl** is brought to you by the following hackers: - - * [Rod Vagg](https://github.com/rvagg) - * [Matteo Collina](https://github.com/mcollina) - * [Jarett Cruger](https://github.com/jcrugzz) - -======= - -<a name="license"></a> -## License & copyright - -Copyright (c) 2013-2018 bl contributors (listed above). - -bl is licensed under the MIT license.
