    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.

    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.

    Detailed Description

    Base class to work with CAD transfer properties. Stores the necessary settings for a single Provider type. Configures and creates special provider to transfer CAD files.

    Nodes are grouped by Vendor's name and Format type. The Vendor name is not defined by default. The Format type is not defined by default. The supported CAD extensions are not defined by default. The import process is not supported. The export process is not supported.

    The algorithm for standalone transfer operation: 1) Create new empty Node object 2) Configure the current Node 2.1) Use the external resource file to configure (::Load) 2.2) Change the internal parameters directly: 2.2.1) Change field values of "GlobalParameters" 2.2.2) Change field values of "InternalParameters" 3) Create one-time transfer provider (::BuildProvider) 4) Initiate the transfer process: 4.1) Import (if "::IsImportSupported: returns TRUE) 4.1.1) Validate the support of input format (::CheckContent or ::CheckExtension) 4.1.2) Use created provider's "::Read" method 4.2) Export (if "::IsExportSupported: returns TRUE) 4.2.1) Use created provider's "::Write" method 5) Check the provider's output
