const XCAFPrs_Style & | DefaultStyle () const |
Return default material definition to be used for nodes with only color defined. | |
void | SetDefaultStyle (const XCAFPrs_Style &theStyle) |
Set default material definition to be used for nodes with only color defined. | |
virtual bool | Perform (const Handle< TDocStd_Document > &theDocument, const TDF_LabelSequence &theRootLabels, const TColStd_MapOfAsciiString *theLabelFilter, const TColStd_IndexedDataMapOfStringString &theFileInfo, const Message_ProgressRange &theProgress) |
Write OBJ file and associated MTL material file. Triangulation data should be precomputed within shapes! | |
virtual bool | Perform (const Handle< TDocStd_Document > &theDocument, const TColStd_IndexedDataMapOfStringString &theFileInfo, const Message_ProgressRange &theProgress) |

![]() | |
Standard_Transient () | |
Empty constructor. | |
Standard_Transient (const Standard_Transient &) | |
Copy constructor – does nothing. | |
Standard_Transient & | operator= (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_Transient * | This () 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 |

virtual void | Delete () const |
Memory deallocator for transient classes. | |
