The code lengths are lens[0..codes-1]. Each length corresponds to the symbols 0..codes-1. The Huffman code is generated by first sorting the symbols by length from short to long, and retaining the symbol order for codes with equal lengths. Then the code starts with all zero bits for the first code of the shortest length, and the codes are integer increments for the same length, and zeros are appended as the length increases. For the deflate format, these bits are stored backwards from their more natural integer increment ordering, and so when the decoding tables are built in the large loop below, the integer codes are incremented backwards. This routine assumes, but does not check, that all of the entries in lens[] are in the range 0..MAXBITS. The caller must assure this. 1..MAXBITS is interpreted as that code length. zero means that that symbol does not occur in this code. The codes are sorted by computing a count of codes for each length, creating from that a table of starting indices for each length in the sorted table, and then entering the symbols in order in the sorted table. The sorted table is work[], with that space being provided by the caller. The length counts are used for other purposes as well, i.e. finding the minimum and maximum length codes, determining if there are any codes at all, checking for a valid set of lengths, and looking ahead at length counts to determine sub-table sizes when building the decoding tables. */ /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */ for (len = 0; len = 1; max--) { if (count[max] !== 0) { break; } } if (root > max) { root = max; } if (max === 0) { /* no symbols to code at all */ //table.op[opts.table_index] = 64; //here.op = (var char)64; /* invalid code marker */ //table.bits[opts.table_index] = 1; //here.bits = (var char)1; //table.val[opts.table_index++] = 0; //here.val = (var short)0; table[table_index++] = (1 0 && (type === CODES || max !== 1)) { return -1; /* incomplete set */ } /* generate offsets into symbol table for each length for sorting */ offs[1] = 0; for (len = 1; len root */ used = 1 ENOUGH_LENS) || (type === DISTS && used > ENOUGH_DISTS)) { return 1; } /* process all codes and make table entries */ for (;;) { /* create table entry */ here_bits = len - drop; if (work[sym] end) { here_op = extra[extra_index + work[sym]]; here_val = base[base_index + work[sym]]; } else { here_op = 32 + 64; /* end of block */ here_val = 0; } /* replicate for those indices with low len bits equal to huff */ incr = 1 > drop) + fill] = (here_bits >= 1; } if (incr !== 0) { huff &= incr - 1; huff += incr; } else { huff = 0; } /* go to next symbol, update count, len */ sym++; if (--count[len] === 0) { if (len === max) { break; } len = lens[lens_index + work[sym]]; } /* create new sub-table if needed */ if (len > root && (huff & mask) !== low) { /* if first time, transition to sub-tables */ if (drop === 0) { drop = root; } /* increment past last table */ next += min; /* here min is 1 ENOUGH_LENS) || (type === DISTS && used > ENOUGH_DISTS)) { return 1; } /* point entry in root table to sub-table */ low = huff & mask; /*table.op[low] = curr; table.bits[low] = root; table.val[low] = next - opts.table_index;*/ table[low] = (root = 0) { buf[len] = 0; } } // From zutil.h var STORED_BLOCK = 0; var STATIC_TREES = 1; var DYN_TREES = 2; /* The three kinds of block type */ var MIN_MATCH = 3; var MAX_MATCH = 258; /* The minimum and maximum match lengths */ // From deflate.h /* =========================================================================== * Internal compression state. */ var LENGTH_CODES = 29; /* number of length codes, not counting the special END_BLOCK code */ var LITERALS = 256; /* number of literal bytes 0..255 */ var L_CODES = LITERALS + 1 + LENGTH_CODES; /* number of Literal or Length codes, including the END_BLOCK code */ var D_CODES = 30; /* number of distance codes */ var BL_CODES = 19; /* number of codes used to transfer the bit lengths */ var HEAP_SIZE = 2 * L_CODES + 1; /* maximum heap size */ var MAX_BITS = 15; /* All codes must not exceed MAX_BITS bits */ var Buf_size = 16; /* size of bit buffer in bi_buf */ /* =========================================================================== * Constants */ var MAX_BL_BITS = 7; /* Bit length codes must not exceed MAX_BL_BITS bits */ var END_BLOCK = 256; /* end of block literal code */ var REP_3_6 = 16; /* repeat previous bit length 3-6 times (2 bits of repeat count) */ var REPZ_3_10 = 17; /* repeat a zero length 3-10 times (3 bits of repeat count) */ var REPZ_11_138 = 18; /* repeat a zero length 11-138 times (7 bits of repeat count) */ /* eslint-disable comma-spacing,array-bracket-spacing */ var extra_lbits = /* extra bits for each length code */ [0,0,0,0,0,0,0,0,1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,5,5,5,5,0]; var extra_dbits = /* extra bits for each distance code */ [0,0,0,0,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13]; var extra_blbits = /* extra bits for each bit length code */ [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,3,7]; var bl_order = [16,17,18,0,8,7,9,6,10,5,11,4,12,3,13,2,14,1,15]; /* eslint-enable comma-spacing,array-bracket-spacing */ /* The lengths of the bit length codes are sent in order of decreasing * probability, to avoid transmitting the lengths for unused bit length codes. */ /* =========================================================================== * Local data.

This second, 'downstream' promise is resolved with the return value of the first promise's fulfillment or rejection handler, or rejected if the handler throws an exception. ```js findUser().then(function (user) { return user.name; }, function (reason) { return 'default name'; }).then(function (userName) { // If `findUser` fulfilled, `userName` will be the user's name, otherwise it // will be `'default name'` }); findUser().then(function (user) { throw new Error('Found user, but still unhappy'); }, function (reason) { throw new Error('`findUser` rejected and we\'re unhappy'); }).then(function (value) { // never reached }, function (reason) { // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. // If `findUser` rejected, `reason` will be '`findUser` rejected and we\'re unhappy'. }); ``` If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. ```js findUser().then(function (user) { throw new PedagogicalException('Upstream error'); }).then(function (value) { // never reached }).then(function (value) { // never reached }, function (reason) { // The `PedgagocialException` is propagated all the way down to here }); ``` Assimilation ------------ Sometimes the value you want to propagate to a downstream promise can only be retrieved asynchronously. This can be achieved by returning a promise in the fulfillment or rejection handler. The downstream promise will then be pending until the returned promise is settled. This is called *assimilation*. ```js findUser().then(function (user) { return findCommentsByAuthor(user); }).then(function (comments) { // The user's comments are now available }); ``` If the assimliated promise rejects, then the downstream promise will also reject. ```js findUser().then(function (user) { return findCommentsByAuthor(user); }).then(function (comments) { // If `findCommentsByAuthor` fulfills, we'll have the value here }, function (reason) { // If `findCommentsByAuthor` rejects, we'll have the reason here }); ``` Simple Example -------------- Synchronous Example ```javascript let result; try { result = findResult(); // success } catch(reason) { // failure } ``` Errback Example ```js findResult(function(result, err){ if (err) { // failure } else { // success } }); ``` Promise Example; ```javascript findResult().then(function(result){ // success }, function(reason){ // failure }); ``` Advanced Example -------------- Synchronous Example ```javascript let author, books; try { author = findAuthor(); books = findBooksByAuthor(author); // success } catch(reason) { // failure } ``` Errback Example ```js function foundBooks(books) { } function failure(reason) { } findAuthor(function(author, err){ if (err) { failure(err); // failure } else { try { findBoooksByAuthor(author, function(books, err) { if (err) { failure(err); } else { try { foundBooks(books); } catch(reason) { failure(reason); } } }); } catch(error) { failure(err); } // success } }); ``` Promise Example; ```javascript findAuthor(). then(findBooksByAuthor). then(function(books){ // found books }).catch(function(reason){ // something went wrong }); ``` @method then @param {Function} onFulfillment @param {Function} onRejection @param {String} label optional string for labeling the promise.

It works in all environments, except IE 10 and below. Consequently all properties of the original function are available to you. However, any properties you change on the denodeified function won't be changed on the original function. Example: ```javascript let request = RSVP.denodeify(require('request')), cookieJar = request.jar(); // 2 && arguments[2] !== undefined ? arguments[2] : true; var label = arguments[3]; return _possibleConstructorReturn$1(this, _Enumerator.call(this, Constructor, object, abortOnReject, label)); } PromiseHash.prototype._init = function _init(Constructor, object) { this._result = {}; this._enumerate(object); if (this._remaining === 0) { fulfill(this.promise, this._result); } }; PromiseHash.prototype._enumerate = function _enumerate(input) { var promise = this.promise; var results = []; for (var key in input) { if (hasOwnProperty.call(input, key)) { results.push({ position: key, entry: input[key] }); } } var length = results.length; this._remaining = length; var result = void 0; for (var i = 0; promise._state === PENDING && i 1; }; RSVP.filter(promises, filterFn).then(function(result){ // result is [ 2, 3 ] }); ``` If any of the `promises` given to `RSVP.filter` are rejected, the first promise that is rejected will be given as an argument to the returned promise's rejection handler. For example: ```javascript let promise1 = RSVP.resolve(1); let promise2 = RSVP.reject(new Error('2')); let promise3 = RSVP.reject(new Error('3')); let promises = [ promise1, promise2, promise3 ]; let filterFn = function(item){ return item > 1; }; RSVP.filter(promises, filterFn).then(function(array){ // Code here never runs because there are rejected promises! }, function(reason) { // reason.message === '2' }); ``` `RSVP.filter` will also wait for any promises returned from `filterFn`. For instance, you may want to fetch a list of users then return a subset of those users based on some asynchronous operation: ```javascript let alice = { name: 'alice' }; let bob = { name: 'bob' }; let users = [ alice, bob ]; let promises = users.map(function(user){ return RSVP.resolve(user); }); let filterFn = function(user){ // Here, Alice has permissions to create a blog post, but Bob does not. return getPrivilegesForUser(user).then(function(privs){ return privs.can_create_blog_post === true; }); }; RSVP.filter(promises, filterFn).then(function(users){ // true, because the server told us only Alice can create a blog post. users.length === 1; // false, because Alice is the only user present in `users` users[0] === bob; }); ``` @method filter @static @for RSVP @param {Array} promises @param {Function} filterFn - function to be called on each resolved value to filter the final results. @param {String} label optional string describing the promise.
