All data is // referenced by a code, which represents one or more values from the // original input stream. All input bytes can be referenced as the same // value as an output code. So if you didn't want any compression, you // could more or less just output the original bytes as codes (there are // some details to this, but it is the idea). In order to achieve // compression, values greater then the input range (codes can be up to // 12-bit while input only 8-bit) represent a sequence of previously seen // inputs. The decompressor is able to build the same mapping while // decoding, so there is always a shared common knowledge between the // encoding and decoder, which is also important for "timing" aspects like // how to handle variable bit width code encoding. // // One obvious but very important consequence of the table system is there // is always a unique id (at most 12-bits) to map the runs. 'A' might be // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship // can be used for an effecient lookup strategy for the code mapping. We // need to know if a run has been seen before, and be able to map that run // to the output code. Since we start with known unique ids (input bytes), // and then from those build more unique ids (table entries), we can // continue this chain (almost like a linked list) to always have small // integer values that represent the current byte chains in the encoder. // This means instead of tracking the input bytes (AAAABCD) to know our // current state, we can track the table entry for AAAABC (it is guaranteed // to exist by the nature of the algorithm) and the next character D. // Therefor the tuple of (table_entry, byte) is guaranteed to also be // unique. This allows us to create a simple lookup key for mapping input // sequences to codes (table indices) without having to store or search // any of the code sequences. So if 'AAAA' has a table entry of 12, the // tuple of ('AAAA', K) for any input byte K will be unique, and can be our // key. This leads to a integer value at most 20-bits, which can always // fit in an SMI value and be used as a fast sparse array / object key. // Output code for the current contents of the index buffer. var ib_code = index_stream[0] & code_mask; // Load first input index. var code_table = {}; // Key'd on our 20-bit "tuple". emit_code(clear_code); // Spec says first code should be a clear code. // First index already loaded, process the rest of the stream. for (var i = 1, il = index_stream.length; i < il; ++i) { var k = index_stream[i] & code_mask; var cur_key = ib_code << 8 | k; // (prev, k) unique tuple. var cur_code = code_table[cur_key]; // buffer + k. // Check if we have to create a new code table entry. if (cur_code === undefined) { // We don't have buffer + k. // Emit index buffer (without k). // This is an inline version of emit_code, because this is the core // writing routine of the compressor (and V8 cannot inline emit_code // because it is a closure here in a different context).
