Tired of getting a firehose worth of data from your streams. This module is here to save the day. PullStream allows you to pull data when you want and as much as you want.
var PullStream = ;var fs = ;var ps = ;var loremIpsumStream = fs;var outputStream = fs;loremIpsumStream;// pull 5 bytesps;
API Documentation ## PullStream ### ps.pull([number], callback)
Calls a callback when the specified number of bytes are ready. If no number is specified pull will read until the end of the input stream.
- number (optional) - Number of bytes to wait for. If not specified reads to the end of input stream.
- callback(err, data) - Callback called when the bytes are ready. data is a buffer containing the bytes.
var ps = ;ps;
Synchronously returns the specified number of bytes or however many bytes are available from the input stream. If no number is specified pullUpTo will return however many bytes are available from the input stream.
- number (optional) - Number of bytes to read from the input stream.
var ps = ;var data = ps;console;
Pipes the specified number of bytes to destStream. If a number is not specified pipe will pipe the remainder of the input stream to destStream. Back-pressure is properly managed.
- number (optional) - Number of bytes to pipe. If not specified pipe the rest of input stream.
- destStream - The stream to pipe data to.
var ps = ;var outputStream = fs;ps;
Consume the specified number of bytes and send them to nowhere. Also drains from upstream as necessary if the specified number of bytes is less than the length of the pull stream's internal buffer.
var ps = ;ps;
Writes data to input side of a pull stream.
- data - Buffer or string to write to the input side of the pull stream.
- encoding (optional) - Encoding to use if data is a string. If not specified 'utf8' is used.
var ps = ;ps;ps;
Manually ends a pull stream.
var ps = ;ps;ps;ps;
Writes data to the front of the input side of a pull stream.
var ps = ;ps;ps;ps;ps;
