- * - options (Object): zlib inflate options.
- *
- * Creates new inflator instance with specified params. Throws exception
- * on bad params. Supported options:
- *
- * - `windowBits`
- * - `dictionary`
- *
- * [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
- * for more information on these.
- *
- * Additional options, for internal needs:
- *
- * - `chunkSize` - size of generated data chunks (16K by default)
- * - `raw` (Boolean) - do raw inflate
- * - `to` (String) - if equal to 'string', then result will be converted
- * from utf8 to utf16 (javascript) string. When string output requested,
- * chunk length can differ from `chunkSize`, depending on content.
- *
- * By default, when no options set, autodetect deflate/gzip data format via
- * wrapper header.
- *
- * ##### Example:
- *
- * ```javascript
- * var pako = require('pako')
- * , chunk1 = Uint8Array([1,2,3,4,5,6,7,8,9])
- * , chunk2 = Uint8Array([10,11,12,13,14,15,16,17,18,19]);
- *
- * var inflate = new pako.Inflate({ level: 3});
- *
- * inflate.push(chunk1, false);
- * inflate.push(chunk2, true); // true -> last chunk

- * if (inflate.err) { throw new Error(inflate.err); }

- * Sends input data to inflate pipe, generating [[Inflate#onData]] calls with
- * new output chunks. Returns `true` on success. The last data block must have
- * mode Z_FINISH (or `true`). That will flush internal pending buffers and call
- * [[Inflate#onEnd]]. For interim explicit flushes (without ending the stream) you

- Process a set of code lengths to create a canonical Huffman code. 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

- of the low root bits of huff. This is saved in low to check for when a

- When a new sub-table is needed, it is necessary to look ahead in the

- entered in the tables.
