 BinLDrivers_DocumentRetrievalDriver ()
 Constructor.
 
virtual void Read (const TCollection_ExtendedString &theFileName, const Handle< CDM_Document > &theNewDocument, const Handle< CDM_Application > &theApplication, const Handle< PCDM_ReaderFilter > &theFilter=Handle< PCDM_ReaderFilter >(), const Message_ProgressRange &theProgress=Message_ProgressRange()) override
 retrieves the content of the file into a new Document.

- Public Member Functions inherited from Standard_Transient
 Standard_Transient ()
 Empty constructor.
 
 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (const Standard_Transient &)
 Assignment operator, needed to avoid copying reference counter.
 
virtual ~Standard_Transient ()
 Destructor must be virtual.
 
virtual const opencascade::handle< Standard_Type > & DynamicType () const
 Returns a type descriptor about this object.
 
Standard_Boolean IsInstance (const opencascade::handle< Standard_Type > &theType) const
 Returns a true value if this is an instance of Type.
 
Standard_Boolean IsInstance (const Standard_CString theTypeName) const
 Returns a true value if this is an instance of TypeName.
 
Standard_Boolean IsKind (const opencascade::handle< Standard_Type > &theType) const
 Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
 
Standard_Boolean IsKind (const Standard_CString theTypeName) const
 Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
 
Standard_TransientThis () const
 Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
 
Standard_Integer GetRefCount () const noexcept
 Get the reference counter of this object.
 
void IncrementRefCounter () noexcept
 Increments the reference counter of this object.
 
Standard_Integer DecrementRefCounter () noexcept
 Decrements the reference counter of this object; returns the decremented value.
 
virtual void Delete () const
 Memory deallocator for transient classes.

virtual Standard_Integer ReadSubTree (Standard_IStream &theIS, const TDF_Label &theData, const Handle< PCDM_ReaderFilter > &theFilter, const Standard_Boolean &theQuickPart, const Message_ProgressRange &theRanges=Message_ProgressRange())
 Read the tree from the stream <theIS> to <theLabel>
 
virtual void ReadSection (BinLDrivers_DocumentSection &theSection, const Handle< CDM_Document > &theDoc, Standard_IStream &theIS)
 define the procedure of reading a section to file.
 
virtual void ReadShapeSection (BinLDrivers_DocumentSection &theSection, Standard_IStream &theIS, const Standard_Boolean isMess=Standard_False, const Message_ProgressRange &theRange=Message_ProgressRange())
 define the procedure of reading a shapes section to file.
 
virtual void CheckShapeSection (const Storage_Position &thePos, Standard_IStream &theIS)
 checks the shapes section can be correctly retrieved.
 
virtual void Clear ()
 clears the reading-cash data in drivers if any.
 
virtual Standard_Boolean CheckDocumentVersion (const Standard_Integer theFileVersion, const Standard_Integer theCurVersion)
 Check a file version(in which file was written) with a current version. Redefining this method is a chance for application to read files written by newer applications. The default implementation: if the version of the file is greater than the current or lesser than 2, then return false, else true.
 
virtual void EnableQuickPartReading (const Handle< Message_Messenger > &, Standard_Boolean)
 Enables reading in the quick part access mode.
 

Static Protected Member Functions

static Standard_Boolean IsQuickPart (const Standard_Integer theFileVer)
 Return true if retrieved document allows to read parts quickly.
