1. Constructor

public MemcachedClient(InetSocketAddress[] ia) throws IOException;

public MemcachedClient(List<InetSocketAddress> addrs) throws IOException;

public MemcachedClient(ConnectionFactory cf, List<InetSocketAddress> addrs) throws IOException;

The simplest constructor is the first one. You can directly pass an inetsocketaddress or an array of inetsocketaddress. In fact, inetsocketaddress is also converted into an array.

For example:

MemcachedClient cache = new MemcachedClient(new InetSocketAddress("127.0.0.1", 11211));

2. Common Methods

Common Operations for caching data include: Set (add + replace), get, replace, and add

public Future<Boolean> set(String key, int exp, Object o)

Third parameter: set the value in the cache. If no value exists, insert the value. If yes, modify the value.

public Object get(String key)

First parameter: Key)

public Future<Boolean> replace(String key, int exp, Object o)
