* @method Hyphenator~convertPatternsToArray
|
||
* @desc
|
||
* converts the patterns to a (typed, if possible) array as described by Liang:
|
||
*
|
||
* 1. Create the CharMap: an alphabet of used character codes mapped to an int (e.g. a: "97" -> 0)
|
||
* This map is bidirectional:
|
||
* charMap.code2int is an object with charCodes as keys and corresponging ints as values
|
||
* charMao.int2code is an array of charCodes at int indizes
|
||
* the length of charMao.int2code is equal the length of the alphabet
|
||
*
|
||
* 2. Create a ValueStore: (typed) array that holds "values", i.e. the digits extracted from the patterns
|
||
* The first value starts at index 1 (since the trie is initialized with zeroes, starting at 0 would create errors)
|
||
* Each value starts with its length at index i, actual values are stored in i + n where n < length
|
||
* Trailing 0 are not stored. So pattern values like e.g. "010200" will become […,4,0,1,0,2,…]
|
||
* The ValueStore-Object manages handling of indizes automatically. Use ValueStore.add(p) to add a running value.
|
||
* Use ValueStore.finalize() when the last value of a pattern is added. It will set the length and return the starting index of the pattern.
|
||
* To prevent doubles we could temporarly store the values in a object {value: startIndex} and only add new values,
|
||
* but this object deoptimizes very fast (new hidden map for each entry); here we gain speed and pay memory
|
||
*
|
||
* 3. Create and zero initialize a (typed) array to store the trie. The trie uses two slots for each entry/node:
|
||
* i: a link to another position in the array or -1 if the pattern ends here or more rows have to be added.
|
||
* i + 1: a link to a value in the ValueStore or 0 if there's no value for the path to this node.
|
||
* Although the array is one-dimensional it can be described as an array of "rows",
|
||
* where each "row" is an array of length trieRowLength (see below).
|
||
* The first entry of this "row" represents the first character of the alphabet, the second a possible link to value store,
|
||
* the third represents the second character of the alphabet and so on…
|
||
*
|
||
* 4. Initialize trieRowLength (length of the alphabet * 2)
|
||
*
|
||
* 5. Now we apply extract to each pattern collection (patterns of the same length are collected and concatenated to one string)
|
||
* extract goes through these pattern collections char by char and adds them either to the ValueStore (if they are digits) or
|
||
* to the trie (adding more "rows" if necessary, i.e. if the last link pointed to -1).
|
||
* So the first "row" holds all starting characters, where the subsequent rows hold the characters that follow the
|
||
* character that link to this row. Therefor the array is dense at the beginning and very sparse at the end.
