    Inheritance diagram for Graphic3d_ShaderVariable:

    Public Member Functions

     ~Graphic3d_ShaderVariable () override
     Releases resources of shader variable.
    const TCollection_AsciiStringName () const
     Returns name of shader variable.
    bool IsDone () const
     Checks if the shader variable is valid or not.
    Graphic3d_ValueInterfaceValue ()
     Returns interface of shader variable value.
    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 ()=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.

    Static Public Member Functions

    template<class T>
    static Graphic3d_ShaderVariableCreate (const TCollection_AsciiString &theName, const T &theValue)
     Creates new initialized shader variable.
    static constexpr const char * get_type_name ()
     Returns a type descriptor about this object.
    static const opencascade::handle< Standard_Type > & get_type_descriptor ()
     Returns type descriptor of Standard_Transient class.

    Protected Member Functions

     Graphic3d_ShaderVariable (const TCollection_AsciiString &theName)
     Creates new uninitialized shader variable.

    Protected Attributes

    TCollection_AsciiString myName
     The name of uniform shader variable.
    Graphic3d_ValueInterfacemyValue
     The generic value of shader variable.

    Additional Inherited Members

    typedef void base_type
     Returns a type descriptor about this object.
