Ternary Search Tree

- * - *

A ternary search tree is a hibrid between a binary tree and - * a digital search tree (trie). Keys are limited to strings. - * A data value of type char is stored in each leaf node. - * It can be used as an index (or pointer) to the data. - * Branches that only contain one key are compressed to one node - * by storing a pointer to the trailer substring of the key. - * This class is intended to serve as base class or helper class - * to implement Dictionary collections or the like. Ternary trees - * have some nice properties as the following: the tree can be - * traversed in sorted order, partial matches (wildcard) can be - * implemented, retrieval of all keys within a given distance - * from the target, etc. The storage requirements are higher than - * a binary tree but a lot less than a trie. Performance is - * comparable with a hash table, sometimes it outperforms a hash - * function (most of the time can determine a miss faster than a hash).

- * - *

The main purpose of this java port is to serve as a base for - * implementing TeX's hyphenation algorithm (see The TeXBook, - * appendix H). Each language requires from 5000 to 15000 hyphenation - * patterns which will be keys in this tree. The strings patterns - * are usually small (from 2 to 5 characters), but each char in the - * tree is stored in a node. Thus memory usage is the main concern. - * We will sacrify 'elegance' to keep memory requirenments to the - * minimum. Using java's char type as pointer (yes, I know pointer - * it is a forbidden word in java) we can keep the size of the node - * to be just 8 bytes (3 pointers and the data char). This gives - * room for about 65000 nodes. In my tests the english patterns - * took 7694 nodes and the german patterns 10055 nodes, - * so I think we are safe.

- * - *

All said, this is a map with strings as keys and char as value. - * Pretty limited!. It can be extended to a general map by - * using the string representation of an object and using the - * char value as an index to an array that contains the object - * values.
