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'); - -/*<replacement>*/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/*</replacement>*/ - -util.inherits(Transform, Duplex); - -function TransformState(stream) { - this.afterTransform = function (er, data) { - return afterTransform(stream, er, data); - }; - - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; - this.writeencoding = null; -} - -function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - <span class="missing-if-branch" title="if path not taken" >I</span>if (!cb) <span class="cstat-no" title="statement not covered" >return stream.emit('error', new Error('no writecb in Transform class'));</span> - - ts.writechunk = null; - ts.writecb = null; - - if (data !== null && data !== undefined) stream.push(data); - - cb(er); - - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } -} - -function Transform(options) { - <span class="missing-if-branch" title="if path not taken" >I</span>if (!(this instanceof Transform)) <span class="cstat-no" title="statement not covered" >return new Transform(options);</span> - - Duplex.call(this, options); - - this._transformState = new TransformState(this); - - // when the writable side finishes, then flush out anything remaining. - var stream = this; - - // 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; - } - - this.once('prefinish', function () { - if (typeof this._flush === 'function') this._flush(function (er) { - done(stream, er); - });else done(stream); - }); -} - -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.
