      • 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
        Overrides:
        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.
      • adjustSqlType

        public java.lang.Class<?> adjustSqlType​(java.lang.Class<?> sqlType)
        For INTEGER type ResultSet.getObject() returns BigDecimal: dependent objects with integer identity cause type conversion error (need to fix SimpleQueryExecutor).
        Specified by:
        adjustSqlType in interface PersistenceFactory
        Overrides:
        adjustSqlType in class BaseFactory
        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.
      • isKeyGeneratorSequenceSupported

        public boolean isKeyGeneratorSequenceSupported​(boolean returning,
                                                       boolean trigger)
        Description copied from class: GenericFactory
        Does persistence factory support generation of new key at the time of new object creation with sequence key generator?
        Specified by:
        isKeyGeneratorSequenceSupported in interface PersistenceFactory
        Overrides:
        isKeyGeneratorSequenceSupported in class GenericFactory
        Parameters:
        returning - Return generated key value with insert statement?
        trigger - Use a database trigger to generate key?
        Returns:
        true if persistence factory is able to generate key with sequence key generator, false otherwise.
      • isKeyGeneratorSequenceTypeSupported

        public boolean isKeyGeneratorSequenceTypeSupported​(int type)
        Does Sequence key generator support generation of key for the given SQL type?
        Specified by:
        isKeyGeneratorSequenceTypeSupported in interface PersistenceFactory
        Overrides:
        isKeyGeneratorSequenceTypeSupported in class GenericFactory
        Parameters:
        type - SQL type to check for support by sequence key generator.
        Returns:
        true if persistence factory is able to generate key of given SQL type with sequence key generator, false otherwise.
      • getSequenceBeforeSelectString

        public java.lang.String getSequenceBeforeSelectString​(java.lang.String seqName,
