Constructor Detail

MemcachedConnection

public MemcachedConnection(int bufSize,
                           ConnectionFactory f,
                           java.util.List<java.net.InetSocketAddress> a,
                           java.util.Collection<ConnectionObserver> obs,
                           FailureMode fm,
                           OperationFactory opfactory)
                    throws java.io.IOException

Construct a memcached connection.

Parameters:

bufSize - the size of the buffer used for reading from the server

f - the factory that will provide an operation queue

a - the addresses of the servers to connect to

Throws:

java.io.IOException - if a connection attempt fails early

Method Detail

setContinuousTimeout

public static void setContinuousTimeout(boolean isIncrease)

whenever timeout exception occur, timeout counter increase by 1 until timeout exception threshold but, if isIncrease is false, timeout counter will be reset

Parameters:

isIncrease -

handleIO

public void handleIO()
              throws java.io.IOException

MemcachedClient calls this method to handle IO over the connections.

Throws:

java.io.IOException

addObserver

public boolean addObserver(ConnectionObserver obs)

Add a connection observer.

Returns:

whether the observer was successfully added

removeObserver

public boolean removeObserver(ConnectionObserver obs)

Remove a connection observer.

Returns:

true if the observer existed and now doesn't

addOperation

public void addOperation(java.lang.String key,
                         Operation o)

Add an operation to the given connection.

Parameters:

key - the key the operation is operating upon

o - the operation

insertOperation

Shut down all of the connections.

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
