Public Member Functions inherited from Standard_Transient | |
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 |
Decrements the reference counter of this object; returns the decremented value. | |
virtual void | Delete () const |
Memory deallocator for transient classes. | |
Static Public Member Functions | |
static Image_Format | FormatFFmpeg2Occt (int theFormat) |
Convert pixel format from FFmpeg (AVPixelFormat) to OCCT. | |
static int | FormatOcct2FFmpeg (Image_Format theFormat) |
Convert pixel format from OCCT to FFmpeg (AVPixelFormat). Returns -1 (AV_PIX_FMT_NONE) if undefined. | |
static void | Swap (const Handle< Media_Frame > &theFrame1, const Handle< Media_Frame > &theFrame2) |
Swap AVFrame* within two frames. | |
Static Public Member Functions inherited from Standard_Transient | |
static constexpr const char * | get_type_name () |
Returns a type descriptor about this object. | |
