 import redis.clients.jedis.Jedis;

// First get a connection
JReJSON client = new JReJSON("localhost", 6379);
 
// Setting a Redis key name _foo_ to the string _"bar"_, and reading it back
client.set("foo", "bar");
String s0 = (String) client.get("foo");
 
// Omitting the path (usually) defaults to the root path, so the call above to
// `get()` and the following ones // are basically interchangeable
String s1 = (String) client.get("foo", new Path("."));
String s2 = (String) client.get("foo", Path.ROOT_PATH);
 
// Any Gson-able object can be set and updated
client.set("obj", new Object());             // just an empty object
client.set("obj", null, new Path(".zilch"));
Path p = new Path(".whatevs");
client.set("obj", true, p);
client.set("obj", 42, p);
client.del("obj", p);                        // back to almost nothing
