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. - - module.exports = Transform; - - var Duplex = __webpack_require__(37); - - /**/ - var util = __webpack_require__(34); - util.inherits = __webpack_require__(35); - /**/ - - util.inherits(Transform, Duplex); - - - function TransformState(options, stream) { - this.afterTransform = function(er, data) { - return afterTransform(stream, er, data); - }; - - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; - } - - function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) - return stream.emit('error', new Error('no writecb in Transform class')); - - ts.writechunk = null; - ts.writecb = null; - - if (!util.isNullOrUndefined(data)) - stream.push(data); - - if (cb) - cb(er); - - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } - } - - - function Transform(options) { - if (!(this instanceof Transform)) - return new Transform(options); - - Duplex.call(this, options); - - this._transformState = new TransformState(options, 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; - - this.once('prefinish', function() { - if (util.isFunction(this._flush)) - 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.
