| virtual void  | Perform (IFSelect_ContextWrite &ctx, StepData_StepWriter &writer) const =0 | 
|   | Perform the action specific to each class of File Modifier <ctx> is the ContextWrite, which brings : the model, the protocol, the file name, plus the object AppliedModifiers (not used here) and the CheckList Remark that the model has to be casted for specific access.  
  | 
|   | 
| Standard_Boolean  | MayChangeGraph () const | 
|   | Returns True if this modifier may change the graph of dependences (aknowledged at creation time)  
  | 
|   | 
| void  | SetDispatch (const Handle< IFSelect_Dispatch > &disp) | 
|   | Attaches to a Dispatch. If <disp> is Null, Resets it (to apply the Modifier on every Dispatch)  
  | 
|   | 
| Handle< IFSelect_Dispatch >  | Dispatch () const | 
|   | Returns the Dispatch to be matched, Null if not set.  
  | 
|   | 
| Standard_Boolean  | Applies (const Handle< IFSelect_Dispatch > &disp) const | 
|   | Returns True if a Model obtained from the Dispatch <disp> is to be treated (apart from the Selection criterium) If Dispatch(me) is Null, returns True. Else, checks <disp>  
  | 
|   | 
| void  | SetSelection (const Handle< IFSelect_Selection > &sel) | 
|   | Sets a Selection : a Model is treated if it contains one or more Entities designated by the Selection.  
  | 
|   | 
| void  | ResetSelection () | 
|   | Resets the Selection : this criterium is not longer active.  
  | 
|   | 
| Standard_Boolean  | HasSelection () const | 
|   | Returns True if a Selection is set as an additional criterium.  
  | 
|   | 
| Handle< IFSelect_Selection >  | Selection () const | 
|   | Returns the Selection, or a Null Handle if not set.  
  | 
|   | 
| virtual TCollection_AsciiString  | Label () const =0 | 
|   | Returns a short text which defines the operation performed.

  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.
