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.

Public Methods

Method	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

Protected Methods

Method	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.

GetInstance ( ) : SockIOPool
GetInstance ( String poolName ) : SockIOPool
GetLocalizedString ( string key ) : string
Initialize ( ) : void
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 method

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

protected static AddSocketToPool ( Hashtable pool, string host, SockIO socket ) : void
pool	System.Collections.Hashtable
host	string	host this socket is connected to
socket	SockIO	socket to add
return	void

ClosePool() protected static method

Closes all sockets in the passed in sockIOPool. Internal utility method.

protected static ClosePool ( Hashtable pool ) : void
pool	System.Collections.Hashtable
return	void

CreateSocket() protected method

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.

protected CreateSocket ( string host ) : SockIO
host	string	host:port to connect to
return	SockIO

GetSock() public method

Returns appropriate SockIO object given string cache key.

public GetSock ( string key ) : SockIO
key	string	hashcode for cache key
return	SockIO

GetSock() public method

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.

public GetSock ( string key, object hashCode ) : SockIO
key	string	hashcode for cache key
hashCode	object	if not null, then the int hashcode to use
return	SockIO

SetServers() public method

Sets the list of all cache servers

public SetServers ( ArrayList servers ) : void
servers	System.Collections.ArrayList	string array of servers [host:port]
return	void

SetServers() public method

Sets the list of all cache servers

public SetServers ( string servers ) : void
servers	string	string array of servers [host:port]
return	void

SetWeights() public method

sets the list of weights to apply to the server list

public SetWeights ( ArrayList weights ) : void
weights	System.Collections.ArrayList	/// This is an int array with each element corresponding to an element /// in the same position in the server string array Servers. ///
return	void

SetWeights() public method

sets the list of weights to apply to the server list

public SetWeights ( int weights ) : void
weights	int	/// This is an int array with each element corresponding to an element /// in the same position in the server string array Servers. ///
return	void

SockIOPool() protected method

protected SockIOPool ( ) : System
return	System
