Method Detail
- initialize
```
public void initialize(AnnotationScanner scanner,
              String[] classpathPrefixArr)
```
  Initialize the manager by scanning the classpath starting with the classpathPrefix, looking for classes annotated with Entity. If an Entity class is found, it looks for the Table annotation to determine the Cassandra column family name.
  
  Parameters:
  classpathPrefixArr -
  See Also:
  ClassCacheMgr
- load
```
@Deprecated
public <T,I> T load(Class<T> clazz,
                      I id)
```
  Deprecated.
- load
```
@Deprecated
public <T> T load(Class<T> clazz,
                    Object id,
                    ColumnSlice<String,byte[]> colSlice)
```
  Deprecated.
- save
```
@Deprecated
public <T> T save(T obj)
```
  Deprecated.
- find
```
public <T> T find(Class<T> clazz,
         Object id)
```
  Load an entity instance. If the ID does not map to a persisted entity, then null is returned.
  
  Specified by:
  
  find in interface javax.persistence.EntityManager
  
  Type Parameters:
  T - The type of entity to load for compile time type checking
  Parameters:
  clazz - The type of entity to load for runtime instance creation
  id - ID of the instance to load
  
  Returns:
  instance of Entity or null if can't be found
- find
```
public <T> T find(Class<T> clazz,
         Object id,
         ColumnSlice<String,byte[]> colSlice)
```
  Load an entity instance given the raw column slice. This is a stop gap solution for instanting objects using entity manager while iterating over rows.
  
  Type Parameters:
  T - The type of entity to load for compile time type checking
  Parameters:
  clazz - The type of entity to load for runtime instance creation
  id - ID of the instance to load
  colSlice - Raw row slice as returned from Hector API, of the type ColumnSlice
  
  Returns:
  Completely instantiated persisted object
- persist
```
public Collection<Object> persist(Collection<Object> objColl)
```
  Save the list of entity intances.
  
  Parameters:
  objColl -
  
  Returns:
- persist
```
public Collection<?> persist(Collection<?> objColl,
                    Mutator<byte[]> m)
```
  Save the list of entity intances.
  
  Parameters:
  objColl -
  
  Returns:
- persist
