  - getKeyGenerator
```
public KeyGenerator getKeyGenerator(ClassDescriptor clsDesc)
                             throws MappingException
```
    Returns a key generator as specified in the given class descriptor.
    
    Specified by:
    
    getKeyGenerator in interface PersistenceFactory
    
    Parameters:
    
    clsDesc - The class descriptor.
    
    Returns:
    
    A suitable key generator or null.
    
    Throws:
    
    MappingException - If creation of key generator fails.
  - getPersistence
```
public Persistence getPersistence(ClassDescriptor clsDesc)
```
    Returns a persistence implementation for the specified object type (given its descriptor) on behalf of the specified cache engine. Return null if no persistence support is available for the specified object type.
    
    Specified by:
    
    getPersistence in interface PersistenceFactory
    
    Parameters:
    
    clsDesc - The class descriptor.
    
    Returns:
    
    A suitable persistence implementation or null.
  - getCallQuery
```
public PersistenceQuery getCallQuery(java.lang.String call,
                                     java.lang.Class<?>[] paramTypes,
                                     java.lang.Class<?> javaClass,
                                     java.lang.String[] fields,
                                     int[] sqlTypes)
```
    Needed to process OQL queries of "CALL" type (using stored procedure call). This feature is specific for JDO.
    
    Specified by:
    
    getCallQuery in interface PersistenceFactory
    
    Parameters:
    
    call - Stored procedure call (without "{call")
    
    paramTypes - The types of the query parameters
    
    javaClass - The Java class of the query results
    
    fields - The field names
    
    sqlTypes - The field SQL types
    
    Returns:
    
    null if this feature is not supported.
  - adjustSqlType
```
public java.lang.Class<?> adjustSqlType(java.lang.Class<?> sqlType)
```
    Some databases has some problems with some SQL types. Usually it is enough to merely replace one SQL type by another.
    
    Specified by:
    
    adjustSqlType in interface PersistenceFactory
    
    Parameters:
    
    sqlType - The correspondent Java class for the SQL type in mapping.xml
    
    Returns:
    
    The correspondent Java class for the SQL type that should be used instead.
