C# 클래스 Majestic12.FastHash

FastHash: class provides fast look ups at the expense of memory (at least 128k per object). Its designed primarily for those hashes where majority of lookups are unsuccessful (ie object is not present) Status of this work is EXPERIMENTAL, do not make any untested assumptions. History: 15/12/06 Added range check in GetXY sometime in 2005: initial imlpementation

상속: IDisposable

메소드	설명
Add ( string sKey ) : void	Adds key to the fast hash
Add ( string sKey, object iValue ) : void	Adds key and its value to the fast hash
Contains ( string sKey ) : bool	Checks if given key is present in the hash
Dispose ( ) : void
FastHash ( ) : System
GetLikelyPresentValue ( byte iX, byte iY ) : object	Returns value for likely present keys using first chars (byte)
GetLikelyPresentValue ( string sKey ) : object	Returns value of a key that is VERY likely to be present - this avoids doing some checks that are most likely to be pointless thus making overall faster function
GetValue ( string sKey ) : object	Returns value associated with the key or null if key not present
GetXY ( string sKey, int &iX, int &iY ) : void
PossiblyContains ( char cChar1, char cChar2, int iLength ) : bool	Quickly checks if given chars POSSIBLY refer to a stored key.
this ( string sKey ) : object	Access to values via indexer
