Summary0019403: Adding DeltaOnModification functioanlity to set of Standard attributes
DescriptionThis patch adds new DeltaOnModification functionality for set of next standard
attributes: ByteArray, IntegerArray, RealArray, ExtStringArray, IntPackeMap.
With this patch the mentioned DeltaOnModification feature becomes ready to use
for specified attributes. The choice use or not this feature is driven by the
corresponding boolean variable <isDelta> of the <Set> command of the attributes.
The attached archive includes:
- <adm> directory with UDLIST file
- <work> directory with srcripts dedicated for attributes testing
- <src> directory with sources.
Additional information
and documentation updates		Documentation remark, added by SZY 2008-04-01 13:30:59:

New features:
Implemented the possibility to use the specified attributes as in standard mode
(default mode) when during CommitTransaction command the full attribute value is
backuping as in DeltaOnModification mode, when only delta of attribute value
relative to old state is backuping. The new feature can be used in case when
attribute's value (array or packed map) expected of very big size and using of
standard backup mode becomes not effective.
The implementation allows using in the same document the same attributes as in
standard mode as in DeltaOnModification mode. The choice is driven by boolean
parameter <isDelta> of the corresponding <Set> command of the specified attribute.
It is ready to use and doesn't requires any additional efforts from a developer.
The mode (Default delta of DeltaonModification) of attribute using is not
supposed to be changed after initial set. If it is requested by an application
business logic the attribute with undesirable mode removed using Forget command).
Changes:
Each modified attribute (using new feature) received new methods:
 GetDelta(me) returns Boolean from Standard;
 ---C++: inline

 SetDelta(me : mutable; isDelta : Boolean from Standard);
 ---C++: inline
 ---Purpose: for internal use only by the class developer!

 RemoveArray(me : mutable) is private;
 ---C++: inline
 DeltaOnModification(me; anOldAttribute : Attribute from TDF)
 returns DeltaOnModification from TDF is redefined virtual;
 ---Purpose : Makes a DeltaOnModification between <me> and
 -- <anOldAttribute>.

and new class supporting DeltaOnModification mechanism:
  TDataStd_DeltaOnModificationOfByteArray,
  TDataStd_DeltaOnModificationOfExtStringArray,
  TDataStd_DeltaOnModificationOfIntArray,
  TDataStd_DeltaOnModificationOfIntPackedMap,
  TDataStd_DeltaOnModificationOfRealArray.

Corresponding persistence classes for all supporting formats (Standard, BinOcaf,
XmlOcaf) were modified too.
