    Get all lines from this polyline

  • IsValid –

    Check if the polygon is valid ( has at least 2 points )

  • LineCount –

    Get the count of lines connecting the points

  • Reverse –

    Reverse orientation of the Polyline

  • __eq__ –

    Equal operator

    Overloaded function. See individual overloads.

  • __init__ –

    Overloaded function. See individual overloads.

  • __ne__ –

    Not equal operator

  • __repr__ –

    Convert to string

GetLine 

GetLine(index: int) -> Line2D

Extract a line

Parameters:

  • index (int) –

    Index of the line

Returns:

  • Line2D –

    Line from the index

GetLines 

GetLines() -> Line2DList

Get all lines from this polyline

Returns:

IsValid 

IsValid() -> bool

Check if the polygon is valid ( has at least 2 points )

For additional point validation use Service::Validate.

Returns:

  • bool –

    true if is valid

LineCount 

LineCount() -> int

Get the count of lines connecting the points

Returns:

  • int –

    count of lines

Reverse 

Reverse()

Reverse orientation of the Polyline

__eq__ 

__eq__(polyline2: Polyline2D) -> bool

Equal operator

Parameters:

Returns:

  • bool –

    Polyline3D are equal

__iadd__ overloaded 

__iadd__(polyline: Polyline2D) -> Polyline2D

Addition assignment operator

Parameters:

  • polyline (Polyline2D) –

    Polyline which will be added

Returns:

__iadd__(point: Point2D) -> Polyline2D

Addition assignment operator

Parameters:

  • point (Point2D) –

    New Point2D which will be added to the polyline

Returns:

__init__ overloaded 

__init__()

Initialize

__init__(pntList: list)

Constructor with an initializer list

Parameters:

  • pntList (list) –

    Point list

__init__(polyline: Polyline2D)

Copy constructor.

Parameters:

__init__(points: Point2DList)

Vector points constructor.

Parameters:

  • points (Point2DList) –

    Vector of points which will be moved to polyline

__init__(polyline: Polyline2D, skip: int, count: int)

Copy constructor with limited scope

Parameters:

  • polyline (Polyline2D) –

    Polyline which will be copied

  • skip (int) –

    count of points ignored at start.

  • count (int) –

    count of points copied.

__init__(polygon: Polygon2D)

Constructor.

If polygon have two or more components, then constructor throw Geometry exception.

Parameters:

  • polygon (Polygon2D) –

    Polygon2D whose points and reference point will build the new polyline
