C# Class Whalin.Caching.Memcached.SockIOPool

This class is a connection sockIOPool for maintaning a sockIOPool of persistent connections to memcached servers. The sockIOPool must be initialized prior to use. This should typically be early on in the lifecycle of the application instance.

Méthodes publiques

Méthode Description
GetSock ( string key ) : SockIO

Returns appropriate SockIO object given string cache key.
GetSock ( string key, object hashCode ) : SockIO

Returns appropriate SockIO object given string cache key and optional hashcode. Trys to get SockIO from sockIOPool. Fails over to additional pools in event of server failure.
SetServers ( ArrayList servers ) : void

Sets the list of all cache servers
SetServers ( string servers ) : void

Sets the list of all cache servers
SetWeights ( ArrayList weights ) : void

sets the list of weights to apply to the server list
SetWeights ( int weights ) : void

sets the list of weights to apply to the server list

Méthodes protégées

Méthode Description
AddSocketToPool ( Hashtable pool, string host, SockIO socket ) : void

Adds a socket to a given sockIOPool for the given host. Internal utility method.
ClosePool ( Hashtable pool ) : void

Closes all sockets in the passed in sockIOPool. Internal utility method.
CreateSocket ( string host ) : SockIO

Creates a new SockIO obj for the given server. If server fails to connect, then return null and do not try again until a duration has passed. This duration will grow by doubling after each failed attempt to connect.
SockIOPool ( ) : System

NewHashingAlgorithm ( string key ) : int

Internal private hashing method. This is the new hashing algorithm from other clients. Found to be fast and have very good distribution. UPDATE: this is dog slow under java. Maybe under .NET?
OriginalHashingAlgorithm ( string key ) : int

Internal private hashing method. This is the original hashing algorithm from other clients. Found to be slow and have poor distribution.

Method Details

AddSocketToPool() protected static méthode

Adds a socket to a given sockIOPool for the given host. Internal utility method.

pool System.Collections.Hashtable
host string host this socket is connected to
socket SockIO socket to add
Résultat void

ClosePool() protected static méthode

Closes all sockets in the passed in sockIOPool. Internal utility method.
protected static ClosePool ( Hashtable pool ) : void
pool System.Collections.Hashtable
Résultat void

CreateSocket() protected méthode

Creates a new SockIO obj for the given server. If server fails to connect, then return null and do not try again until a duration has passed. This duration will grow by doubling after each failed attempt to connect.
