public class Polyline2DObject
extends X3DConcreteNode
implements Polyline2D

Polyline2D is a geometry node that defines a connected set of vertices in a contiguous set of line segments in X-Y plane.

X3D node tooltip: [X3DGeometryNode] Polyline2D is a geometry node that defines a connected set of vertices in a contiguous set of line segments in X-Y plane.

Hint: Material emissiveColor in corresponding Appearance is used for rendering lines.
Warning: lines are not lit, are not texture-mapped, and do not participate in collision detection.
Warning: use a different Material emissiveColor than the Background color, otherwise geometry is invisible.
Hint: adding LineProperties to the corresponding Appearance node can modify the rendering style of these lines.
Hint: insert a Shape node before adding geometry or Appearance. Examples: X3D Example Archives, X3D for Web Authors, Chapter 10 Geometry 2D https://x3dgraphics.com/examples/X3dForWebAuthors/Chapter10Geometry2D

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.

- setUSE
  
  public Polyline2DObject setUSE(Polyline2DObject DEFnode)
  
  Assign a USE reference to another DEF node of same node type, similar to setUSE(String).
  
  Warning: note that the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.
  
  Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.
  
  Parameters:
  
  DEFnode - must have a DEF value defined
  
  Returns:
  
  Polyline2DObject - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

- findElementByNameValue
  
  public X3DConcreteElement findElementByNameValue(java.lang.String nameValue)

  Specified by:
  
  findElementByNameValue in class X3DConcreteElement
  
  Parameters:
  
  nameValue - is value of the name field being searched for in this element and child elements(if any)
  
  Returns:
  
  object reference to found element, null otherwise
