public final class InstantDBFactory
extends GenericFactory

Persistence factory for InstantDB database (http://instantdb.enhydra.org/ ).

Example database.xml file for JDO

   <database name="test" engine="instantdb" >
       <driver class-name="org.enhydra.instantdb.jdbc.idbDriver" 
               url="jdbc:idb:C:\\castor-0.8.8\\db\\test\\test.prp">
         <param name="user" value="" />
         <param name="password" value="" />
       </driver>
       <mapping href="mapping.xml" />
    </database>

    Description copied from interface: PersistenceFactory
    
    Returns the name of this factory. A descriptive name that indicates the type of supported database server or SQL syntax.
    
    Specified by:
    
    getFactoryName in interface PersistenceFactory
    
    Overrides:
    
    getFactoryName in class GenericFactory
    
    Returns:
    
    The name of this factory
  - getQueryExpression
```
public QueryExpression getQueryExpression()
```
    Description copied from interface: PersistenceFactory
    
    Returns a new empty query expression suitable for the underlying SQL engine. The implementation will construct SQL query statements in the preferred syntax.
    
    Specified by:
    
    getQueryExpression in interface PersistenceFactory
    
    Overrides:
    
    getQueryExpression in class GenericFactory
    
    Returns:
    
    New empty query expression
  - 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:
    
    adjustSqlType in interface PersistenceFactory
    
    Overrides:
    
    adjustSqlType in class BaseFactory
