Implementation of new format for quick reading and writing parts of the documents (sub-set of labels and sub-set of attributes). It consists in writing shapes and all their contents right in the TNaming_NamedShape attribute placement and skipping the shape section. New format 12 for Binary file types is assigned to this version.
Added PCDM_ReaderFilter class that could be used in Open methods of TDocStd_Application. If it is defined, it allows to read:
- into already opened document in append mode AppendMode_Protect (do not overwrite existing attributes) or AppendMode_Overwrite
- only specified sub-trees of the document using AddPath (const TCollection_AsciiString& theEntryToRead)
- only specified attributes using AddRead (const TCollection_AsciiString& theRead) where theRead could be "TDataStd_Name", for example
- to skip specified attributes read using AddSkipped (const TCollection_AsciiString& theSkipped) where theSkipped could be "TDF_Reference", for example
The current limitations:
- only in Bin format
- if shapes have in the document shared topology, loaded in "append" mode in different "load" operations, they will have no shared topology anymore
Modifications:
BinLDrivers and BinDrivers packages - modifications related to the quick part tree format flag usage, skipping shape section writing and adding labels sizes into the document to be able to pass labels during the reading quickly.
BinObjMgt_Persistent and BinObjMgt_Position - to add possibility to write directly into the stream some data just after the attribute. Before this record a data-size is recorded.
BinMXCAFDoc package modifications to write BinMXCAFDoc_LocationDriver location in the same way as shapes write location data right after the attribute (empty) data in this new format.
BinTools package: creation of ShapeReader and ShapeWriter classes with same root class ShapeSetBase with ShapeSet class. These classes allows to write/read shapes directly to the stream. If some object is already in the stream, write a reference - relative position of the duplicated object. The old format of documents is still supported by Bin_ToolsShapeSet class.
PCDM_ReaderFilter - Allows the user to create a reading filter. It contains algorithm to browse labels tree quickly, without usage of referencing by entry-strings.
TDocStd, CDF and some other packages are changed for supporting reading filters API and options.
Tests, documentation and upgrade information are also added for both issues: 31839 and 31918 related to this commit.
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Add support of Message_ProgressIndicator in BinTools classes.
Add support of Message_ProgressIndicator with possibility of user break in methods of opening and saving TDocStd_Application.
Add tests of ProgressIndicator in TDocStd_Applacation.
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.
Eliminated empty constructors.
Updated samples.
Eliminate empty method ChangeValue from NCollection_Map class.
Removed not operable methods from NCollection classes.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
