//! Storage format versions of OCAF documents in XML and binary file formats.
|
|
//!
|
|
//! OCAF document file format evolves and a new version number indicates each improvement of the
|
|
//! format. This enumeration lists all versions of an OCAF document. TDocStd_FormatVersion_CURRENT
|
|
//! value refers to the last file format version. By default, Open CASCADE Technology writes new
|
|
//! documents using the last file format version. The last version of Open CASCADE Technology is
|
|
//! able to read old documents of any version. However, a previous version of Open CASCADE
|
|
//! Technology may not be able to read a new document. In this case use the method
|
|
//! ChangeStorageFormatVersion() from TDocStd_Document to change the file format version. Then, save
|
|
//! the document by means of SaveAs() from TDocStd_Application.
|
|
//!
|
|
//! If it is necessary to improve an XML or binary file format of OCAF document, follow please the
|
|
//! next steps:
|
|
//! - increment the file format version in this enumeration. Put a reference to the last file format
|
|
//! version by means of TDocStd_FormatVersion_CURRENT.
|
|
//! - introduce the improvement in OCAF attribute storage and retrieval drivers, if necessary.
|
|
//! As an example, please consider the file XmlMDataStd_TreeNodeDriver.cxx.
|
|
//! - test the improvement on current file format version and on the previous one.
