This holds the field and assorted store specific options. Field Summary public  boolean doNotFetchObject      This flag is used to include reference fields in a fetch group and to fetch only the OID of the reference and not the referenced object as well. public  JdoExtension extension      The parsed meta data for this field (null if none i.e. public  FieldMetaData fmd      The field. public  String jdbcSelectSql      Cache for SQL required to fetch this field. public  String jdbcSelectSqlForUpdate      Cache for SQL required to fetch this field when selectForUpdate is on. This is normally only used for pass 2 fields e.g. public  int jdbcUseJoin      If this is a ref or a collection then this is the useJoin option to use when this group is fetched. public  int jdbcUseKeyJoin      If this is a map and the keys are a PC class then this is the useJoin option to use when this group is fetched. public  FetchGroup nextFetchGroup      If a store does read ahead (e.g. public  FetchGroup nextKeyFetchGroup      If a store does read ahead (e.g. Constructor Summary public   FetchGroupField(FieldMetaData field)      Method Summary public  void dump()      public  void dump(PrintStream out, String indent)      public  String toString()      Field Detail doNotFetchObject public boolean doNotFetchObject(Code) This flag is used to include reference fields in a fetch group and to fetch only the OID of the reference and not the referenced object as well. extension public JdoExtension extension(Code) The parsed meta data for this field (null if none i.e. automatically generated default fetch group). fmd public FieldMetaData fmd(Code) The field. jdbcSelectSql public String jdbcSelectSql(Code) Cache for SQL required to fetch this field. This is normally only used for pass 2 fields e.g. collections and so on. jdbcSelectSqlForUpdate public String jdbcSelectSqlForUpdate(Code) Cache for SQL required to fetch this field when selectForUpdate is on. This is normally only used for pass 2 fields e.g. collections and so on. jdbcUseJoin public int jdbcUseJoin(Code) If this is a ref or a collection then this is the useJoin option to use when this group is fetched. The fields picked up by the join will be those in the nextFetchGroup of the referenced class. Values are from JdbcField: USE_JOIN_NO USE_JOIN_INNER USE_JOIN_OUTER. See Also:   FetchGroupField.nextFetchGroup jdbcUseKeyJoin public int jdbcUseKeyJoin(Code) If this is a map and the keys are a PC class then this is the useJoin option to use when this group is fetched. The fields picked up by the join will be those in the nextKeyFetchGroup of the referenced class. Values are from JdbcField: USE_JOIN_NO USE_JOIN_INNER USE_JOIN_OUTER. See Also:   FetchGroupField.nextKeyFetchGroup nextFetchGroup public FetchGroup nextFetchGroup(Code) If a store does read ahead (e.g. a JDBC store using a join) and this field is a reference to another PC class then get the fields in this fetch group of that class. This will never be null as it is set to the default fetch group if not specified. nextKeyFetchGroup public FetchGroup nextKeyFetchGroup(Code) If a store does read ahead (e.g. a JDBC store using a join) and this field is a map and the keys reference another PC class then get the fields in this fetch group of that class. This will never be null as it is set to the default fetch group if not specified.
