boolean hasRegisteredCallbacks(Class<?> entityClass,
                               CallbackType callbackType)
```
    Do we have any registered callbacks of the given type for the given entity?
    
    Parameters:
    
    entityClass - The entity Class to check against
    
    callbackType - The type of callback to look for
    
    Returns:
    
    true indicates there are already registered callbacks of that type for that class; false indicates there are not.
  - preCreate
```
void preCreate(Object entity)
```
  - postCreate
```
void postCreate(Object entity)
```
  - preUpdate
```
boolean preUpdate(Object entity)
```
  - postUpdate
```
void postUpdate(Object entity)
```
  - preRemove
```
void preRemove(Object entity)
```
  - postRemove
```
void postRemove(Object entity)
```
  - postLoad
```
boolean postLoad(Object entity)
```
  - release

    Signals that the CallbackRegistry will no longer be used. In particular, it is important to release references to class types to avoid classloader leaks.
