 Poly_Polygon2D (const Standard_Integer theNbNodes) 
 Constructs a 2D polygon with specified number of nodes. More...


 Poly_Polygon2D (const TColgp_Array1OfPnt2d &Nodes) 
 Constructs a 2D polygon defined by the table of points, <Nodes>. More...


Standard_Real  Deflection () const 
 Returns the deflection of this polygon. Deflection is used in cases where the polygon is an approximate representation of a curve. Deflection represents the maximum distance permitted between any point on the curve and the corresponding point on the polygon. By default the deflection value is equal to 0. An algorithm using this 2D polygon with a deflection value equal to 0 considers that it is working with a true polygon and not with an approximate representation of a curve. The Deflection function is used to modify the deflection value of this polygon. The deflection value can be used by any algorithm working with 2D polygons. For example: More...


void  Deflection (const Standard_Real theDefl) 
 Sets the deflection of this polygon. More...


Standard_Integer  NbNodes () const 
 Returns the number of nodes in this polygon. Note: If the polygon is closed, the point of closure is repeated at the end of its table of nodes. Thus, on a closed triangle, the function NbNodes returns 4. More...


const TColgp_Array1OfPnt2d &  Nodes () const 
 Returns the table of nodes for this polygon. More...


TColgp_Array1OfPnt2d &  ChangeNodes () 
 Returns the table of nodes for this polygon. More...


virtual void  DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=1) const 
 Dumps the content of me into the stream. More...


Public Member Functions inherited from Standard_Transient 
 Standard_Transient () 
 Empty constructor. More...


 Standard_Transient (const Standard_Transient &) 
 Copy constructor – does nothing. More...


Standard_Transient &  operator= (const Standard_Transient &) 
 Assignment operator, needed to avoid copying reference counter. More...


virtual  ~Standard_Transient () 
 Destructor must be virtual. More...


virtual void  Delete () const 
 Memory deallocator for transient classes. More...


virtual const opencascade::handle< Standard_Type > &  DynamicType () const 
 Returns a type descriptor about this object. More...


Standard_Boolean  IsInstance (const opencascade::handle< Standard_Type > &theType) const 
 Returns a true value if this is an instance of Type. More...


Standard_Boolean  IsInstance (const Standard_CString theTypeName) const 
 Returns a true value if this is an instance of TypeName. More...


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. More...


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. More...


Standard_Transient *  This () const 
 Returns nonconst 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. More...


Standard_Integer  GetRefCount () const 
 Get the reference counter of this object. More...


void  IncrementRefCounter () const 
 Increments the reference counter of this object. More...


Standard_Integer  DecrementRefCounter () const 
 Decrements the reference counter of this object; returns the decremented value. More...
