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\n'use strict';\n\nmodule.exports = Transform;\n\nvar Duplex = require('./_stream_duplex');\n\n/**/\nvar util = Object.create(require('core-util-is'));\nutil.inherits = require('inherits');\n/**/\n\nutil.inherits(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n var ts = this._transformState;\n ts.transforming = false;\n\n var cb = ts.writecb;\n\n if (!cb) {\n return this.emit('error', new Error('write callback called multiple times'));\n }\n\n ts.writechunk = null;\n ts.writecb = null;\n\n if (data != null) // single equals check for both `null` and `undefined`\n this.push(data);\n\n cb(er);\n\n var rs = this._readableState;\n rs.reading = false;\n if (rs.needReadable || rs.length < rs.highWaterMark) {\n this._read(rs.highWaterMark);\n }\n}\n\nfunction Transform(options) {\n if (!(this instanceof Transform)) return new Transform(options);\n\n Duplex.call(this, options);\n\n this._transformState = {\n afterTransform: afterTransform.bind(this),\n needTransform: false,\n transforming: false,\n writecb: null,\n writechunk: null,\n writeencoding: null\n };\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 if (options) {\n if (typeof options.transform === 'function') this._transform = options.transform;\n\n if (typeof options.flush === 'function') this._flush = options.flush;\n }\n\n // When the writable side finishes, then flush out anything remaining.\n this.on('prefinish', prefinish);\n}\n\nfunction prefinish() {\n var _this = this;\n\n if (typeof this._flush === 'function') {\n this._flush(function (er, data) {\n done(_this, er, data);\n });\n } else {\n done(this, null, null);\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.

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\n  inherits$1(Transform, Duplex);\n\n  function TransformState(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    this.writeencoding = null;\n  }\n\n  function afterTransform(stream, er, data) {\n    var ts = stream._transformState;\n    ts.transforming = false;\n\n    var cb = ts.writecb;\n\n    if (!cb) 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) stream.push(data);\n\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  function Transform(options) {\n    if (!(this instanceof Transform)) return new Transform(options);\n\n    Duplex.call(this, options);\n\n    this._transformState = new TransformState(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    if (options) {\n      if (typeof options.transform === 'function') this._transform = options.transform;\n\n      if (typeof options.flush === 'function') this._flush = options.flush;\n    }\n\n    this.once('prefinish', function () {\n      if (typeof this._flush === 'function') this._flush(function (er) {\n        done(stream, er);\n      });else done(stream);\n    });\n  }\n\n  Transform.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.

The Huffman code is generated by first sorting the\n     symbols by length from short to long, and retaining the symbol order\n     for codes with equal lengths.  Then the code starts with all zero bits\n     for the first code of the shortest length, and the codes are integer\n     increments for the same length, and zeros are appended as the length\n     increases.  For the deflate format, these bits are stored backwards\n     from their more natural integer increment ordering, and so when the\n     decoding tables are built in the large loop below, the integer codes\n     are incremented backwards.\n\n     This routine assumes, but does not check, that all of the entries in\n     lens[] are in the range 0..MAXBITS.  The caller must assure this.\n     1..MAXBITS is interpreted as that code length.  zero means that that\n     symbol does not occur in this code.\n\n     The codes are sorted by computing a count of codes for each length,\n     creating from that a table of starting indices for each length in the\n     sorted table, and then entering the symbols in order in the sorted\n     table.  The sorted table is work[], with that space being provided by\n     the caller.\n\n     The length counts are used for other purposes as well, i.e. finding\n     the minimum and maximum length codes, determining if there are any\n     codes at all, checking for a valid set of lengths, and looking ahead\n     at length counts to determine sub-table sizes when building the\n     decoding tables.\n     */\n\n    /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */\n    for (len = 0; len <= MAXBITS; len++) {\n      count[len] = 0;\n    }\n    for (sym = 0; sym < codes; sym++) {\n      count[lens[lens_index + sym]]++;\n    }\n\n    /* bound code lengths, force root to be within code lengths */\n    root = bits;\n    for (max = MAXBITS; max >= 1; max--) {\n      if (count[max] !== 0) {\n        break;\n      }\n    }\n    if (root > max) {\n      root = max;\n    }\n    if (max === 0) { /* no symbols to code at all */\n      //table.op[opts.table_index] = 64;  //here.op = (var char)64;    /* invalid code marker */\n      //table.bits[opts.table_index] = 1;   //here.bits = (var char)1;\n      //table.val[opts.table_index++] = 0;   //here.val = (var short)0;\n      table[table_index++] = (1 << 24) | (64 << 16) | 0;\n\n\n      //table.op[opts.table_index] = 64;\n      //table.bits[opts.table_index] = 1;\n      //table.val[opts.table_index++] = 0;\n      table[table_index++] = (1 << 24) | (64 << 16) | 0;\n\n      opts.bits = 1;\n      return 0; /* no symbols, but wait for decoding to report error */\n    }\n    for (min = 1; min < max; min++) {\n      if (count[min] !== 0) {\n        break;\n      }\n    }\n    if (root < min) {\n      root = min;\n    }\n\n    /* check for an over-subscribed or incomplete set of lengths */\n    left = 1;\n    for (len = 1; len <= MAXBITS; len++) {\n      left <<= 1;\n      left -= count[len];\n      if (left < 0) {\n        return -1;\n      } /* over-subscribed */\n    }\n    if (left > 0 && (type === CODES$1 || max !== 1)) {\n      return -1; /* incomplete set */\n    }\n\n    /* generate offsets into symbol table for each length for sorting */\n    offs[1] = 0;\n    for (len = 1; len < MAXBITS; len++) {\n      offs[len + 1] = offs[len] + count[len];\n    }\n\n    /* sort symbols by length, by symbol order within each length */\n    for (sym = 0; sym < codes; sym++) {\n      if (lens[lens_index + sym] !== 0) {\n        work[offs[lens[lens_index + sym]]++] = sym;\n      }\n    }\n\n    /*\n     Create and fill in decoding tables.  In this loop, the table being\n     filled is at next and has curr index bits.  The code being used is huff\n     with length len.  That code is converted to an index by dropping drop\n     bits off of the bottom.  For codes where len is less than drop + curr,\n     those top drop + curr - len bits are incremented through all values to\n     fill the table with replicated entries.\n\n     root is the number of index bits for the root table.  When len exceeds\n     root, sub-tables are created pointed to by the root entry with an index\n     of the low root bits of huff.  This is saved in low to check for when a\n     new sub-table should be started.  drop is zero when the root table is\n     being filled, and drop is root when sub-tables are being filled.\n\n     When a new sub-table is needed, it is necessary to look ahead in the\n     code lengths to determine what size sub-table is needed.  The length\n     counts are used for this, and so count[] is decremented as codes are\n     entered in the tables.\n\n     used keeps track of how many table entries have been allocated from the\n     provided *table space.  It is checked for LENS and DIST tables against\n     the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in\n     the initial root table size constants.  See the comments in inftrees.h\n     for more information.\n\n     sym increments through all symbols, and the loop terminates when\n     all codes of length max, i.e. all codes, have been processed.
