Empty constructor. More... | |
Public Member Functions inherited from RWGltf_PrimitiveArrayReader | |
RWGltf_PrimitiveArrayReader () | |
Constructor. More... | |
const TCollection_AsciiString & | ErrorPrefix () const |
Return prefix for reporting issues. More... | |
void | SetErrorPrefix (const TCollection_AsciiString &theErrPrefix) |
Set prefix for reporting issues. More... | |
const RWMesh_CoordinateSystemConverter & | CoordinateSystemConverter () const |
Return transformation from glTF to OCCT coordinate system. More... | |
void | SetCoordinateSystemConverter (const RWMesh_CoordinateSystemConverter &theConverter) |
Set transformation from glTF to OCCT coordinate system. More... | |

Public Member Functions inherited from Standard_Transient | |
Standard_Transient () | |
Empty constructor. More... | |
Standard_Transient (const Standard_Transient &) | |
Copy constructor – does nothing. More... | |
Standard_Transient & | operator= (const Standard_Transient &) |
Assignment operator, needed to avoid copying reference counter. More... | |
virtual | ~Standard_Transient () |
Destructor must be virtual. More... | |
virtual void | Delete () const |
Memory deallocator for transient classes. More... | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
Returns a type descriptor about this object. More... | |
Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
Returns a true value if this is an instance of Type. More... | |
Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
Returns a true value if this is an instance of TypeName. More... | |
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. More... | |
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. More... | |
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. More... | |
