      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.

      getQueryExpression in interface PersistenceFactory
      Overrides:
      getQueryExpression in class GenericFactory
      Returns:
      New empty query expression

    • quoteName

      public String quoteName(String name)
      Description copied from interface: PersistenceFactory
      Returns the quoted identifier suitable for preventing conflicts between database identifiers and reserved keywords.
      Specified by:
      quoteName in interface PersistenceFactory
      Overrides:
      quoteName in class GenericFactory
      Parameters:
      name - The identifier (table, column, etc)
      Returns:
      The quoted identifier

    • getCallQuery

      public PersistenceQuery getCallQuery(String call, Class<?>[] paramTypes, Class<?> javaClass, 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

      getCallQuery in class BaseFactory
      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.

      isKeyGeneratorIdentitySupported in interface PersistenceFactory
      Overrides:
      isKeyGeneratorIdentitySupported in class GenericFactory
      Returns:
      true if persistence factory is able to generate unique keys with identity key generator, false otherwise.

    • isKeyGeneratorIdentityTypeSupported

      public boolean isKeyGeneratorIdentityTypeSupported(int type)
      Description copied from class: GenericFactory
