# buffer.Buffer > The `Buffer` class is a global type for dealing with binary data directly. It can be constructed in a variety of ways. - Source: https://titaniumsdk.com/docs/sdk/12.6.4/buffer.Buffer - Titanium SDK version: 12.6.4 - Kind: pseudo - Platforms: Android, iPhone, iPad, macOS - Since: Titanium SDK 8.2.0 Note that this `Buffer` class is highly related to the [Titanium.Buffer](https://titaniumsdk.com/docs/sdk/Titanium.Buffer.md) type. Both are wrappers around an underlying array of bytes and can be accessed in an array-like manner: ``` javascript const value = buffer[index]; buffer[index] = 1; ``` In fact, this Node.js shim has been written to allow wrapping a [Titanium.Buffer](https://titaniumsdk.com/docs/sdk/Titanium.Buffer.md) into a Node.js compatible instance: ``` javascript const wrapped = Buffer.from(tiBuffer); ``` Note that this will result in a **slow** `Buffer` instance (because reads/writes pass-through to the underlying `Ti.Buffer` which in turn goes through the JS/native binding layer). If you only intend to *read* the data (or do not need to write back to the original [Titanium.Buffer](https://titaniumsdk.com/docs/sdk/Titanium.Buffer.md)) you can perform a one-time copy of the underlying bytes to a faster JS-only `Uint8Array`: ```javascript const fastBuffer = Buffer.from(tiBuffer.toBlob().toArrayBuffer()); // here we're converting from Blob to Ti.Buffer to ArrayBuffer and the shim wraps that copy ``` ## Properties ### buffer - Type: ArrayBuffer - Platforms: Android, iPhone, iPad, macOS The underlying `ArrayBuffer` object based on which this `Buffer` object is created. This `ArrayBuffer` is not guaranteed to correspond exactly to the original `Buffer`. See the notes on [buffer.Buffer.byteOffset](https://titaniumsdk.com/docs/sdk/buffer.Buffer.md#byteOffset) for details. ### byteOffset - Type: Number - Platforms: Android, iPhone, iPad, macOS The `byteOffset` of the `Buffer`s underlying `ArrayBuffer` object. ### length - Type: Number - Platforms: Android, iPhone, iPad, macOS Returns the number of bytes in buf. ## Methods ### compare - Platforms: Android, iPhone, iPad, macOS Compares `buf` with `target` and returns a number indicating whether buf comes before, after, or is the same as target in sort order. Comparison is based on the actual sequence of bytes in each `Buffer`. `0` is returned if target is the same as buf `1` is returned if target should come before buf when sorted. `-1` is returned if target should come after buf when sorted. Parameters: - `target` (buffer.Buffer | Uint8Array): A `Buffer` or `Uint8Array` with which to compare buf. - `targetStart` (Number, optional): The offset within target at which to begin comparison. Default: `0`. - `targetEnd` (Number, optional): The offset within target at which to end comparison (not inclusive). Default: ``target.length``. - `sourceStart` (Number, optional): The offset within buf at which to begin comparison. Default: `0`. - `sourceEnd` (Number, optional): The offset within buf at which to end comparison (not inclusive). Default: ``buf.length``. Returns: Number ### copy - Platforms: Android, iPhone, iPad, macOS Copies data from a region of `buf` to a region in `target`, even if the target memory region overlaps with `buf`. Parameters: - `target` (buffer.Buffer | Uint8Array): A `Buffer` or `Uint8Array` with which to compare buf. - `targetStart` (Number, optional): The offset within target at which to begin writing. Default: `0`. - `sourceStart` (Number, optional): The offset within buf at which to begin copying. Default: `0`. - `sourceEnd` (Number, optional): The offset within buf at which to stop copying (not inclusive). Default: ``buf.length``. Returns: Number - The number of bytes copied. ### entries - Platforms: Android, iPhone, iPad, macOS Creates and returns an [iterator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#The_iterator_protocol) of `[index, byte]` pairs from the contents of `buf`. Returns: Object ### equals - Platforms: Android, iPhone, iPad, macOS Returns `true` if both `buf` and `otherBuffer` have exactly the same bytes, false otherwise. Equivalent to `buf.compare(otherBuffer) === 0`. Parameters: - `otherBuffer` (buffer.Buffer | Uint8Array): A `Buffer` or `Uint8Array` with which to compare buf. Returns: Boolean ### fill - Platforms: Android, iPhone, iPad, macOS Fills `buf` with the specified value. If the `offset` and `end` are not given, the entire `buf` will be filled. Parameters: - `value` (String | Number | buffer.Buffer | Uint8Array): The value with which to fill `buf`. - `offset` (Number, optional): Number of bytes to skip before starting to fill `buf`. Default: `0`. - `end` (Number, optional): Where to stop filling `buf` (not inclusive). Default: ``buf.length``. - `encoding` (String, optional): The encoding for `value` if `value` is a string. Default: ``'utf8'``. Returns: buffer.Buffer - A reference to `buf`. ### includes - Platforms: Android, iPhone, iPad, macOS Equivalent to `buf.indexOf() !== -1`. Parameters: - `value` (String | Number | buffer.Buffer | Uint8Array): What to search for. - `byteOffset` (Number, optional): Where to begin searching in `buf`. If negative, then offset is calculated from the end of `buf`. Default: `0`. - `encoding` (String, optional): If `value` is a string, this is its encoding. Default: ``'utf8'``. Returns: Boolean - `true` if `value` was found in buf, `false` otherwise. ### indexOf - Platforms: Android, iPhone, iPad, macOS If value is: - a string, `value` is interpreted according to the character encoding in `encoding`. - a `Buffer` or `Uint8Array`, value will be used in its entirety. To compare a partial `Buffer`, use [buf.slice()](https://titaniumsdk.com/docs/sdk/buffer.Buffer.md#slice). - a number, `value` will be interpreted as an unsigned 8-bit integer value between `0` and `255`. Parameters: - `value` (String | Number | buffer.Buffer | Uint8Array): What to search for. - `byteOffset` (Number, optional): Where to begin searching in `buf`.
