    Public Member Functions

     Graphic3d_StructureManager (const occ::handle< Graphic3d_GraphicDriver > &theDriver)
     Initializes the ViewManager. Currently creating of more than 100 viewer instances is not supported and leads to InitializationError and initialization failure. This limitation might be addressed in some future OCCT releases. Warning: Raises InitialisationError if the initialization of the ViewManager failed.

    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 &)

    virtual ~Standard_Transient ()=default
     Destructor must be virtual.
    virtual const opencascade::handle< Standard_Type > & DynamicType () const
     Returns a type descriptor about this object.
    bool IsInstance (const opencascade::handle< Standard_Type > &theType) const
     Returns a true value if this is an instance of Type.
    bool IsInstance (const char *const theTypeName) const
     Returns a true value if this is an instance of TypeName.
    bool 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.
    bool IsKind (const char *const 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.
    int GetRefCount () const noexcept
     Get the reference counter of this object.
    void IncrementRefCounter () noexcept
     Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
    int DecrementRefCounter () noexcept
     Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
    virtual void Delete () const
     Memory deallocator for transient classes.

    Protected Member Functions

    int NumberOfDisplayedStructures () const
     Returns the number of structures displayed in visualizer <me>. Returns the structure displayed in visualizer <me>.
