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.
Class Standard_BaseDriver is inherited from Standard_Transient, its descendants are updated accordingly.
Handle is used to manipulate objects of this class and its descendants (instead of references or raw pointers) to ensure automatic destruction.
Added test bugs caf bug31546
Related:
- Standard_OVERRIDE is added in declarations of virtual methods in descendants of Storage_BaseDriver
- Methods operator << and operator >> are removed in descendants of Storage_BaseDriver (they repeat the same methods inherited from the base class)
- Typedef PCDM_BaseDriverPointer is marked as deprecated
- Unused class DDI_Ostream is removed
- Private field Standard_Transient::count is renamed to myRefCount_ to avoid compiler warnings if the same name is used within the scope of a descendant class
- Output of meaningful error messages is restored in DRAW commands fsdread and fsdwrite
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.
1) Add protection against accessing null pointer in PCDM_ReadWriter::FileFormat.
2) In LDOM_XmlReader::ReadRecord, take into account that the character '>' can have no special meaning (e.g., in a text), and we must read the data behind this character to complete the current tag reading. This treatment concerns the mode of work when myTagPerStep is true.
3) Create a test case of reading of XML file not related to OCAF document.
Test case was added.
XmlOcaf reading is non-seekable
// 1. Read method of XmlLDrivers_DocumentRetrievalDriver extended to read complete document (with "document" tag) in compatible mode (when reading is performed from file)
// 2. the empty statement removed
// 3. the description of LDOMPARSER::parse method extended
Added basic support for possibility to read filed in old persistent format.
Toolkits TKStd, TKStdL, TKShape added to provide necessary tools (to be done).
Obsolete interfaces are removed from classes in PCDM and Storage.
TDocStd_Application class extended to open/save a document of XmlOcaf and BinOcaf format
from/to standard SEEKABLE stream object which should support SEEK functionality.
Open and SaveAs DRAW commands got new additional argument "-stream" to turn on using of stream functionality.
The main changes for BinOcaf format applied in:
FSD_BinaryFile class (static method using standard stream added)
BinLDrivers_DocumentRetrievalDriver and BinLDrivers_DocumentStorageDriver classes use standard stream object as an argument
The main changes for XmlOcaf format applied in:
LDOMParser and LDOM_XmlWriter classes use standard stream object as an argument
Unused class FSD_Archive and its siblings removed from MFC samples.
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
Initial UNICODE (UFT-8) characters support for OCCT file operations
Fix for compilation errors and fix for StepFile (avoid objects in pure c code)
Fixes for set unicode symbols to OCAF and visualization
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.
