          K id)
```
    Description copied from interface: RLiveObjectService
    Finds the entity from Redis with the id. The entityClass should have a field annotated with RId, and the entityClass itself should have REntity annotated. The type of the RId can be anything except the followings:
    1. An array i.e. byte[], int[], Integer[], etc.
    2. or a RObject i.e. RedissonMap
    3. or a Class with REntity annotation.
    Specified by:
    
    get in interface RLiveObjectService
    
    Type Parameters:
    T - Entity type
    K - Key type
    Parameters:
    entityClass - Entity class
    id - identifier
    
    Returns:
    a proxied object if it exists in redis, or null if not.
  - attach
```
public <T> T attach(T detachedObject)
```
    Description copied from interface: RLiveObjectService
    
    Returns proxied object for the detached object. Discard all the field values already in the detached instance. The class representing this object should have a field annotated with RId, and the object should hold a non null value in that field. If this object is not in redis then a new blank proxied instance with the same RId field value will be created.
    
    Specified by:
    
    attach in interface RLiveObjectService
    
    Type Parameters:
    T - Entity type
    Parameters:
    detachedObject - - not proxied object
    
    Returns:
    proxied object
  - merge
```
public <T> T merge(T detachedObject)
```
    Description copied from interface: RLiveObjectService
    
    Returns proxied object for the detached object. Transfers all the NON NULL field values to the redis server. It does not delete any existing data in redis in case of the field value is null. The class representing this object should have a field annotated with RId, and the object should hold a non null value in that field. If this object is not in redis then a new hash key will be created to store it.
    
    Specified by:

  - registerClass
```
public void registerClass(Class cls)
```
    Description copied from interface: RLiveObjectService
    
    Pre register the class with the service, registering all the classes on startup can speed up the instance creation. This is NOT mandatory since the class will also be registered lazily when it is first used. All classed registered with the service is stored in a class cache. The cache is independent between different RedissonClient instances. When a class is registered in one RLiveObjectService instance it is also accessible in another RLiveObjectService instance so long as they are created by the same RedissonClient instance.
    
    Specified by:
    
    registerClass in interface RLiveObjectService
    
    Parameters:
    cls - - class
  - unregisterClass
```
public void unregisterClass(Class cls)
```
    Description copied from interface: RLiveObjectService
    
    Unregister the class with the service. This is useful after you decide the class is no longer required. A class will be automatically unregistered if the service encountered any errors during proxying or creating the object, since those errors are not recoverable. All classed registered with the service is stored in a class cache. The cache is independent between different RedissonClient instances. When a class is registered in one RLiveObjectService instance it is also accessible in another RLiveObjectService instance so long as they are created by the same RedissonClient instance.
    
    Specified by:
    
    unregisterClass in interface RLiveObjectService
    
    Parameters:
    cls - It can be either the proxied class or the unproxied conterpart.
  - isClassRegistered
```
public boolean isClassRegistered(Class cls)
```
    Description copied from interface: RLiveObjectService
    
    Check if the class is registered in the cache. All classed registered with the service is stored in a class cache. The cache is independent between different RedissonClient instances. When a class is registered in one RLiveObjectService instance it is also accessible in another RLiveObjectService instance so long as they are created by the same RedissonClient instance.
    
    Specified by:
    
    isClassRegistered in interface RLiveObjectService
    
    Parameters:
    cls - - type of instance
    
    Returns:
    true if class already registered
