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. + this._readableState = new ReadableState(options, this); -module.exports = Transform; + // legacy + this.readable = true; -var Duplex = require('./_stream_duplex'); + Stream.call(this); +} -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ +// Manually shove something into the read() buffer. +// This returns true if the highWaterMark has not been hit yet, +// similar to how Writable.write() returns true if you should +// write() some more. +Readable.prototype.push = function(chunk, encoding) { + var state = this._readableState; -util.inherits(Transform, Duplex); + if (util.isString(chunk) && !state.objectMode) { + encoding = encoding || state.defaultEncoding; + if (encoding !== state.encoding) { + chunk = new Buffer(chunk, encoding); + encoding = ''; + } + } + return readableAddChunk(this, state, chunk, encoding, false); +}; -function TransformState(options, stream) { - this.afterTransform = function(er, data) { - return afterTransform(stream, er, data); - }; +// Unshift should *always* be something directly out of read() +Readable.prototype.unshift = function(chunk) { + var state = this._readableState; + return readableAddChunk(this, state, chunk, '', true); +}; - 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')); +function readableAddChunk(stream, state, chunk, encoding, addToFront) { + var er = chunkInvalid(state, chunk); + if (er) { + stream.emit('error', er); + } else if (util.isNullOrUndefined(chunk)) { + state.reading = false; + if (!state.ended) + onEofChunk(stream, state); + } else if (state.objectMode || chunk && chunk.length > 0) { + if (state.ended && !addToFront) { + var e = new Error('stream.push() after EOF'); + stream.emit('error', e); + } else if (state.endEmitted && addToFront) { + var e = new Error('stream.unshift() after end event'); + stream.emit('error', e); + } else { + if (state.decoder && !addToFront && !encoding) + chunk = state.decoder.write(chunk); - ts.writechunk = null; - ts.writecb = null; + if (!addToFront) + state.reading = false; - if (!util.isNullOrUndefined(data)) - stream.push(data); + // if we want the data now, just emit it. + if (state.flowing && state.length === 0 && !state.sync) { + stream.emit('data', chunk); + stream.read(0); + } else { + // update the buffer info. + state.length += state.objectMode ? 1 : chunk.length; + if (addToFront) + state.buffer.unshift(chunk); + else + state.buffer.push(chunk); - if (cb) - cb(er); + if (state.needReadable) + emitReadable(stream); + } - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); + maybeReadMore(stream, state); + } + } else if (!addToFront) { + state.reading = false; } + + return needMoreData(state); } -function Transform(options) { - if (!(this instanceof Transform)) - return new Transform(options); - Duplex.call(this, options); +// if it's past the high water mark, we can push in some more. +// Also, if we have no data yet, we can stand some +// more bytes.

(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.
