Constructor Detail

MemcachedServer

public MemcachedServer(Bucket bucket,
                       String hostname,
                       int port,
                       VBucketInfo[] vbi,
                       boolean cccpEnabled)
                throws IOException

Create a new new memcached server.

Parameters:

bucket - The bucket owning all of the stores

hostname - The hostname to connect to (null == any)

port - The port this server should listen to (0 to choose an ephemeral port)

vbi - Vbucket Info

Throws:

IOException - If we fail to create the server socket
