    Parameters:
    
    entityName - The name of the entity loaded.
  - fetchEntity
```
void fetchEntity(String entityName)
```
    Callback about an entity being fetched. Unlike loadEntity(java.lang.String) this indicates a separate query being performed.
    
    Parameters:
    
    entityName - The name of the entity fetched.
  - updateEntity
```
void updateEntity(String entityName)
```
    Callback about an entity being updated.
    
    Parameters:
    
    entityName - The name of the entity updated.
  - insertEntity
```
void insertEntity(String entityName)
```
    Callback about an entity being inserted
    
    Parameters:
    
    entityName - The name of the entity inserted
  - deleteEntity
```
void deleteEntity(String entityName)
```

    entityName - The name of the entity deleted.
  - optimisticFailure
```
void optimisticFailure(String entityName)
```
    Callback about an optimistic lock failure on an entity
    
    Parameters:
    
    entityName - The name of the entity.

    role - The collection role.
  - fetchCollection
```
void fetchCollection(String role)
```
    Callback to indicate a collection being fetched. Unlike loadCollection(java.lang.String), this indicates a separate query was needed.
