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. - default: - if (loweredCase) throw new TypeError('Unknown encoding: ' + encoding) - encoding = (encoding + '').toLowerCase() - loweredCase = true - } +'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); } } -// This property is used by `Buffer.isBuffer` (and the `is-buffer` npm package) -// to detect a Buffer instance.

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.

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.

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';
