// a transform stream is a readable/writable stream where you do
|
||
// something with the data. 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.

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