Sometimes it's called a "filter", + // but that's not a great name for it, since that implies a thing where + // some bits pass through, and others are simply ignored. (That would + // be a valid example of a transform, of course.) + // + // While the output is causally related to the input, it's not a + // necessarily symmetric or synchronous transformation. For example, + // a zlib stream might take multiple plain-text writes(), and then + // emit a single compressed chunk some time in the future. + // + // Here's how this works: + // + // The Transform stream has all the aspects of the readable and writable + // stream classes. When you write(chunk), that calls _write(chunk,cb) + // internally, and returns false if there's a lot of pending writes + // buffered up. When you call read(), that calls _read(n) until + // there's enough pending readable data buffered up. + // + // In a transform stream, the written data is placed in a buffer. When + // _read(n) is called, it transforms the queued up data, calling the + // buffered _write cb's as it consumes chunks. If consuming a single + // written chunk would result in multiple output chunks, then the first + // outputted bit calls the readcb, and subsequent chunks just go into + // the read buffer, and will cause it to emit 'readable' if necessary. + // + // This way, back-pressure is actually determined by the reading side, + // since _read has to be called to start processing a new chunk. However, + // a pathological inflate type of transform can cause excessive buffering + // here. For example, imagine a stream where every byte of input is + // interpreted as an integer from 0-255, and then results in that many + // bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in + // 1kb of data being output. In this case, you could write a very small + // amount of input, and end up with a very large amount of output. In + // such a pathological inflating mechanism, there'd be no way to tell + // the system to stop doing the transform. A single 4MB write could + // cause the system to run out of memory. + // + // However, even in such a pathological case, only a single written chunk + // would be consumed, and then the rest would wait (un-transformed) until + // the results of the previous transformed chunk were consumed. + + "use strict"; + + module.exports = Transform; + + var Duplex = require("./_stream_duplex"); + + /**/ + var util = require("core-util-is"); + util.inherits = require("inherits"); + /**/ + + util.inherits(Transform, Duplex); + + function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) { + return this.emit( + "error", + new Error("write callback called multiple times") + ); + } + + ts.writechunk = null; + ts.writecb = null; + + if (data != null) + // single equals check for both `null` and `undefined` + this.push(data); + + cb(er); + + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } + } + + function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + + Duplex.call(this, options); + + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + if (options) { + if (typeof options.transform === "function") + this._transform = options.transform; + + if (typeof options.flush === "function") + this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.on("prefinish", prefinish); + } + + function prefinish() { + var _this = this; + + if (typeof this._flush === "function") { + this._flush(function(er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } + } + + Transform.prototype.push = function(chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); + }; + + // This is the part where you do stuff! + // override this function in implementation classes. + // 'chunk' is an input chunk. + // + // Call `push(newChunk)` to pass along transformed output + // to the readable side.
