All Known Implementing Classes:

AbstractStoreManager, FederatedStoreManager
```
public interface StoreManager
```
Interface defining management of a datastore. To be implemented by all new datastore support. Please use AbstractStoreManager and extend it. All StoreManagers should have a single constructor with signature
```
 public MyStoreManager(ClassLoaderResolver clr, NucleusContext ctx, Map<String, Object> props)
 {
 }
 
```
The constructor arguments are
- ClassLoader Resolver, for assistance in any class loading needed.
- The context where the StoreManager is being used, providing services like metadata, etc
- Any persistence properties that are defined for the store, to configure schema generation etc
See also AbstractStoreManager which provides something that can be extended, simplifying the process of implementing a StoreManager; note that the first argument of the constructor to AbstractStoreManager is the "key" for your StoreManager (e.g ODF has "odf" as its key, RDBMS has "rdbms").
