If consuming a single\r\n  // written chunk would result in multiple output chunks, then the first\r\n  // outputted bit calls the readcb, and subsequent chunks just go into\r\n  // the read buffer, and will cause it to emit 'readable' if necessary.\r\n  //\r\n  // This way, back-pressure is actually determined by the reading side,\r\n  // since _read has to be called to start processing a new chunk.  However,\r\n  // a pathological inflate type of transform can cause excessive buffering\r\n  // here.  For example, imagine a stream where every byte of input is\r\n  // interpreted as an integer from 0-255, and then results in that many\r\n  // bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in\r\n  // 1kb of data being output.  In this case, you could write a very small\r\n  // amount of input, and end up with a very large amount of output.  In\r\n  // such a pathological inflating mechanism, there'd be no way to tell\r\n  // the system to stop doing the transform.  A single 4MB write could\r\n  // cause the system to run out of memory.\r\n  //\r\n  // However, even in such a pathological case, only a single written chunk\r\n  // would be consumed, and then the rest would wait (un-transformed) until\r\n  // the results of the previous transformed chunk were consumed.\r\n\r\n  'use strict';\r\n\r\n  module.exports = Transform;\r\n\r\n  var Duplex = require('./_stream_duplex');\r\n\r\n  /*<replacement>*/\r\n  var util = require('core-util-is');\r\n  util.inherits = require('inherits');\r\n  /*</replacement>*/\r\n\r\n  util.inherits(Transform, Duplex);\r\n\r\n  function TransformState(stream) {\r\n    this.afterTransform = function (er, data) {\r\n      return afterTransform(stream, er, data);\r\n    };\r\n\r\n    this.needTransform = false;\r\n    this.transforming = false;\r\n    this.writecb = null;\r\n    this.writechunk = null;\r\n    this.writeencoding = null;\r\n  }\r\n\r\n  function afterTransform(stream, er, data) {\r\n    var ts = stream._transformState;\r\n    ts.transforming = false;\r\n\r\n    var cb = ts.writecb;\r\n\r\n    if (!cb) return stream.emit('error', new Error('no writecb in Transform class'));\r\n\r\n    ts.writechunk = null;\r\n    ts.writecb = null;\r\n\r\n    if (data !== null && data !== undefined) stream.push(data);\r\n\r\n    cb(er);\r\n\r\n    var rs = stream._readableState;\r\n    rs.reading = false;\r\n    if (rs.needReadable || rs.length < rs.highWaterMark) {\r\n      stream._read(rs.highWaterMark);\r\n    }\r\n  }\r\n\r\n  function Transform(options) {\r\n    if (!(this instanceof Transform)) return new Transform(options);\r\n\r\n    Duplex.call(this, options);\r\n\r\n    this._transformState = new TransformState(this);\r\n\r\n    // when the writable side finishes, then flush out anything remaining.\r\n    var stream = this;\r\n\r\n    // start out asking for a readable event once data is transformed.\r\n    this._readableState.needReadable = true;\r\n\r\n    // we have implemented the _read method, and done the other things\r\n    // that Readable wants before the first _read call, so unset the\r\n    // sync guard flag.\r\n    this._readableState.sync = false;\r\n\r\n    if (options) {\r\n      if (typeof options.transform === 'function') this._transform = options.transform;\r\n\r\n      if (typeof options.flush === 'function') this._flush = options.flush;\r\n    }\r\n\r\n    this.once('prefinish', function () {\r\n      if (typeof this._flush === 'function') this._flush(function (er) {\r\n        done(stream, er);\r\n      });else done(stream);\r\n    });\r\n  }\r\n\r\n  Transform.prototype.push = function (chunk, encoding) {\r\n    this._transformState.needTransform = false;\r\n    return Duplex.prototype.push.call(this, chunk, encoding);\r\n  };\r\n\r\n  // This is the part where you do stuff!\r\n  // override this function in implementation classes.\r\n  // 'chunk' is an input chunk.\r\n  //\r\n  // Call `push(newChunk)` to pass along transformed output\r\n  // to the readable side.

Sometimes it's called a \"filter\",\r\n  // but that's not a great name for it, since that implies a thing where\r\n  // some bits pass through, and others are simply ignored.  (That would\r\n  // be a valid example of a transform, of course.)\r\n  //\r\n  // While the output is causally related to the input, it's not a\r\n  // necessarily symmetric or synchronous transformation.  For example,\r\n  // a zlib stream might take multiple plain-text writes(), and then\r\n  // emit a single compressed chunk some time in the future.\r\n  //\r\n  // Here's how this works:\r\n  //\r\n  // The Transform stream has all the aspects of the readable and writable\r\n  // stream classes.  When you write(chunk), that calls _write(chunk,cb)\r\n  // internally, and returns false if there's a lot of pending writes\r\n  // buffered up.  When you call read(), that calls _read(n) until\r\n  // there's enough pending readable data buffered up.\r\n  //\r\n  // In a transform stream, the written data is placed in a buffer.  When\r\n  // _read(n) is called, it transforms the queued up data, calling the\r\n  // buffered _write cb's as it consumes chunks.  If consuming a single\r\n  // written chunk would result in multiple output chunks, then the first\r\n  // outputted bit calls the readcb, and subsequent chunks just go into\r\n  // the read buffer, and will cause it to emit 'readable' if necessary.\r\n  //\r\n  // This way, back-pressure is actually determined by the reading side,\r\n  // since _read has to be called to start processing a new chunk.  However,\r\n  // a pathological inflate type of transform can cause excessive buffering\r\n  // here.  For example, imagine a stream where every byte of input is\r\n  // interpreted as an integer from 0-255, and then results in that many\r\n  // bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in\r\n  // 1kb of data being output.  In this case, you could write a very small\r\n  // amount of input, and end up with a very large amount of output.  In\r\n  // such a pathological inflating mechanism, there'd be no way to tell\r\n  // the system to stop doing the transform.  A single 4MB write could\r\n  // cause the system to run out of memory.\r\n  //\r\n  // However, even in such a pathological case, only a single written chunk\r\n  // would be consumed, and then the rest would wait (un-transformed) until\r\n  // the results of the previous transformed chunk were consumed.\r\n  'use strict';\r\n\r\n  module.exports = Transform;\r\n\r\n  var _require$codes = require('../errors').codes,\r\n      ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED,\r\n      ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK,\r\n      ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING,\r\n      ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0;\r\n\r\n  var Duplex = require('./_stream_duplex');\r\n\r\n  require('inherits')(Transform, Duplex);\r\n\r\n  function afterTransform(er, data) {\r\n    var ts = this._transformState;\r\n    ts.transforming = false;\r\n    var cb = ts.writecb;\r\n\r\n    if (cb === null) {\r\n      return this.emit('error', new ERR_MULTIPLE_CALLBACK());\r\n    }\r\n\r\n    ts.writechunk = null;\r\n    ts.writecb = null;\r\n    if (data != null) // single equals check for both `null` and `undefined`\r\n      this.push(data);\r\n    cb(er);\r\n    var rs = this._readableState;\r\n    rs.reading = false;\r\n\r\n    if (rs.needReadable || rs.length < rs.highWaterMark) {\r\n      this._read(rs.highWaterMark);\r\n    }\r\n  }\r\n\r\n  function Transform(options) {\r\n    if (!(this instanceof Transform)) return new Transform(options);\r\n    Duplex.call(this, options);\r\n    this._transformState = {\r\n      afterTransform: afterTransform.bind(this),\r\n      needTransform: false,\r\n      transforming: false,\r\n      writecb: null,\r\n      writechunk: null,\r\n      writeencoding: null\r\n    }; // start out asking for a readable event once data is transformed.\r\n\r\n    this._readableState.needReadable = true; // we have implemented the _read method, and done the other things\r\n    // that Readable wants before the first _read call, so unset the\r\n    // sync guard flag.\r\n\r\n    this._readableState.sync = false;\r\n\r\n    if (options) {\r\n      if (typeof options.transform === 'function') this._transform = options.transform;\r\n      if (typeof options.flush === 'function') this._flush = options.flush;\r\n    } // When the writable side finishes, then flush out anything remaining.\r\n\r\n\r\n    this.on('prefinish', prefinish);\r\n  }\r\n\r\n  function prefinish() {\r\n    var _this = this;\r\n\r\n    if (typeof this._flush === 'function' && !this._readableState.destroyed) {\r\n      this._flush(function (er, data) {\r\n        done(_this, er, data);\r\n      });\r\n    } else {\r\n      done(this, null, null);\r\n    }\r\n  }\r\n\r\n  Transform.prototype.push = function (chunk, encoding) {\r\n    this._transformState.needTransform = false;\r\n    return Duplex.prototype.push.call(this, chunk, encoding);\r\n  }; // This is the part where you do stuff!\r\n  // override this function in implementation classes.\r\n  // 'chunk' is an input chunk.\r\n  //\r\n  // Call `push(newChunk)` to pass along transformed output\r\n  // to the readable side.
