(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. +// Overrided methods // -// 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'; +overrided.forEach(function(method) { + Node.prototype[method] = function _overrided() { + var state = this._baseState; + throw new Error(method + ' not implemented for encoding: ' + state.enc); + }; +}); -module.exports = Transform; +// +// Public methods +// -var Duplex = require('./_stream_duplex'); +tags.forEach(function(tag) { + Node.prototype[tag] = function _tagMethod() { + var state = this._baseState; + var args = Array.prototype.slice.call(arguments); -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ + assert(state.tag === null); + state.tag = tag; -util.inherits(Transform, Duplex); + this._useArgs(args); -function TransformState(stream) { - this.afterTransform = function (er, data) { - return afterTransform(stream, er, data); + return this; }; +}); - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; - this.writeencoding = null; -} +Node.prototype.use = function use(item) { + var state = this._baseState; -function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; + assert(state.use === null); + state.use = item; - var cb = ts.writecb; + return this; +}; - if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); +Node.prototype.optional = function optional() { + var state = this._baseState; - ts.writechunk = null; - ts.writecb = null; + state.optional = true; - if (data !== null && data !== undefined) stream.push(data); + return this; +}; - cb(er); +Node.prototype.def = function def(val) { + var state = this._baseState; - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } -} + assert(state['default'] === null); + state['default'] = val; + state.optional = true; -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); + return this; +}; - Duplex.call(this, options); +Node.prototype.explicit = function explicit(num) { + var state = this._baseState; - this._transformState = new TransformState(this); + assert(state.explicit === null && state.implicit === null); + state.explicit = num; - // when the writable side finishes, then flush out anything remaining. - var stream = this; + return this; +}; - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; +Node.prototype.implicit = function implicit(num) { + var state = this._baseState; - // 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; + assert(state.explicit === null && state.implicit === null); + state.implicit = num; - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; + return this; +}; - if (typeof options.flush === 'function') this._flush = options.flush; - } +Node.prototype.obj = function obj() { + var state = this._baseState; + var args = Array.prototype.slice.call(arguments); - this.once('prefinish', function () { - if (typeof this._flush === 'function') this._flush(function (er) { - done(stream, er); - });else done(stream); - }); -} + state.obj = true; -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; + if (args.length !== 0) + this._useArgs(args); -// 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.

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 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; + + if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); + + 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) { + if (!(this instanceof Transform)) return new Transform(options); + + 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.
