• DataDictionary : DataSet
  **************************************************************************// // EXTENDED_DATA_SET // // This is the extended version of the Data_Set class. // // It provides the following extra's to the standard Data_Set class: // // - SETTING ITEM-OPTIONS PER FIELD // These item-options will be used automatically when an DEO is used // which recognizes the Extended_Data_Set. You can specify two types of // item-options. // 1. The ones that will be used when the Server of the DEO is the same // as the Data_File of the item. We call those the stadard-item- // options. // 2. The ones that will be used when the Server of the DEO is different // from the Data_File of the item. We call those options Foreign- // item-options. // // - PROTECTING KEY FIELDS // You can set the Key_Field_State of a field to true to identify Key- // fields. When the property Protect_Key_State is TRUE (Default) then // a user will not be able to change the value of a field which has been // marked as Key-field from an existing record. // // - VALIDATING FIELDS // A validation message can be set per field. This message will be // executed when the Data_Set needs to validate all fields. The message // will also be send when a DEO need to validate an item. // // - FIELD ENTRY AND EXITS MESSAGES // One can specify a message which has to be send to the Data_Set when // a item of a DEO is being entered or exited. // // Currently the fieldtypes Overlap, Text and Binary are *not* supported. // // PROPERTIES // // EXISTING_KEY_VALUE // This property will hold the complete value of all the fields which // have been flagged to be a key-field. It is used to check if a user // has changed one of the fields which make up the key for a record. // // PROTECT_KEY_STATE // When this property is TRUE, is will force a key to be read-only. A // transaction will be aborted when this Data_Set detects that a key // value for an existing record has been changed. // // KEY_FIELDS // This property contains a comma separated list of all fieldnumbers // which have been marked to be part of a key. This list is not sorted // and should be considered read-only. // // FOREIGN_FIELD_OPTIONS PRIVATE // This property hold the fields' item-options which are copied to a // DEO item when this field is used as a foreign (related) field. // These options will be applied for fields which are not part of an // index. // // FOREIGN_KEY_FIELD_OPTIONS PRIVATE // See Foreign_Field_Options. // These options will be applied for fields which are part of the key. // // FOREIGN_INDEX_FIELD_OPTIONS PRIVATE // See Foreign_Field_Options. // These options will be applied for fields which are part of an index, // but not of a key. // // **************************************************************************// JVH

    • Integer[]pAutoIncrementFields
      used by the set Field_auto_increment method these are split into two arrays to make searching for the field easier the arrays should always be synched.

    • IntegerError_Report_Mode
      Error Reporting Related If DD_Error_No_Report errors would be supressed (only ERR gets set)
    • integerCurrent_Validate_Field
      During validation, this is the field being validated.
    • integerOld_Error_Object_Id
      when errors are redirected locally this maintains the original handler.
    • integerError_Processing_State
      Must be provided if local error handler is to be created
    • IntegerValidate_DEOs_Only_State
      These should be changed most carefully and possible only and the DSO level. These allow you to defeat full field validation which makes it easier to corrupt data! Validate_DEO_Only_State limits save validation to DEOs (which is what data-sets have always done). Validate_foreign_File_State will skip validation under the following conditions: 1) DSO if for a parent (it did not originate the save).
    • IntegerValidate_Foreign_File_State
    • IntegerValidate_All_Fields_State
      if set true, a field validation requested started with this DD will check all fields, even in an error is encountered
    • IntegerEntryUpdateLocalState
      If true, all entry updates will occur through the DD. Else saves occur through the DD and find occur through the DEOs
    • integerFind_Record_Id
      can be used by Refind_records method (remote refind of recs). Obsolete. Use Find_RowId
    • RowIdFind_RowId
      can be used by Refind_records method (remote refind of recs)
    • IntegerField_Objects
      Private: Id of field_objects container. This is not created until needed
    • IntegerAllow_Foreign_New_Save_State
      Public: If set the DDO will never be foreign, allowing you to create new parents when a child is saved. This would normally only be set within the DDO and not the class. This would be used where a child table wants to save the parent (header) when the first child is saved. It would disable the foreign key and index find_Req and required settings (as well as any displayonly).
    • IntegerpbDDAttach
      This makes the attach use the DD structure instead of just doing an attach on all open files. Existing programs should work fine with this. If they don't, you can reset this in your class (although it would be smarter to find out why it is not working.
    • Record_Buffer : Record_Buffer
      Create the local buffer.
    • Field_Attributes : Field_Attributes
      Create the extended field attributes array.

    This is a smarter attach than the normal attach command. It only attaches data from a parent if 1) the DDO parent is connected to the structure and 2) if there is a record to attach. It will not attach empty records into a child. This should make the finding (and saving) more sensible when partial DD structures are used. For example, often a report does not all of the parent DDOs - however if they are not provided, finding can get messed up because blank data is being moved into the child before a find. This has been a problem since 3.0. This should just make it go away.

The old message has the problem that the DDO or DSO using this message may not be the owner of the field. So augmenting the owner DDO did not insure that all requests for this index would go through it. Now you can augment Field_Index and always be sure that any DDO requesting an index for a file (via file_field_index) will always go to the owner object.

Get Field_Current_Value now checks if operation_mode is non-zero. If it is, it always gets from the DD buffer.
