Tokyo Cabinet的Tokyo Cabinet 是一個(gè)DBM的實(shí)現(xiàn)。這里的數(shù)據(jù)庫(kù)由一系列Key-Value對(duì)的記錄構(gòu)成。key和value都可以是任意長(zhǎng)度的字節(jié)序列,既可以是二進(jìn)制也可以是字符串。這里沒(méi)有數(shù)據(jù)類(lèi)型和數(shù)據(jù)表的概念。 作者叫Mikio Hirabayashi.Tokyo Cabinet是用C寫(xiě)的,同時(shí)提供c,perl,ruby,java的API。Tokyo Cabinet在提供了POSIX和C99的平臺(tái)上都可用,它以GNU Lesser Public License協(xié)議發(fā)布。

雜湊法(Hashing)的搜尋與一般的搜尋法(searching)是不一樣的。在雜湊法中,鍵值(key value)或識(shí)別字(identifier)在記憶體的位址是經(jīng)由函數(shù)(function)轉(zhuǎn)換而得的。此種函數(shù),一般稱之為雜湊函數(shù)(Hashing function)或鍵值對(duì)應(yīng)位址轉(zhuǎn)換(key to address transformation)。對(duì)於有限的儲(chǔ)存空間,能夠有效使用且在加入或刪除時(shí)也能快的完成,利用雜湊法是最適當(dāng)不過(guò)了。因?yàn)殡s湊表搜尋在沒(méi)有碰撞(collision)及溢位(overflow)的情況下,只要一次就可擷取到。

Collection of Key-Value pairs. TDictionary represents a generic collection of Key-Value pairs. This class provides a mapping from a collection of keys to a collection of values. When you create a TDictionary object, you can specify various combinations of initial capacity, equality operation, and initial content. You can add a key that is associated with a corresponding value with the Add or AddOrSetValue methods. You can remove entries with Remove or Clear, which removes all Key-Value pairs. Adding or removing a Key-Value pair and looking up a key are efficient, close to O(1), because keys are hashed. A key must not be nil (though a value may be nil) and there must be an equality comparison operation for keys. You can test for the presence or keys and values with the TryGetValue, ContainsKey and ContainsValue methods. The Items property lists all Count dictionary entries. You can also set and get values by indexing the Items property. Setting the value this way overwrites any existing value. The class TObjectDictionary inherits from TDictionary and provides an automatic mechanism for freeing objects removed from dictionary entries.
