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.
