All Implemented Interfaces:

DxfStructure
```
public class DxfLWPolyline
extends DxfEntity
```
A DXF LWPOLYLINE entity.
A LWPOLYLINE represents not just a multi-segment polyline in 3D space, but also allows specification of extrusions and bulges, so the segments may in fact be curves. A LWPOLYLINE is a more compact version of a POLYLINE; it uses repeated coordinate groups instead of individual VERTEX objects. More recent versions of AutoCAD automagically convert most POLYLINE objects to LWPOLYLINE objects when loading.
Representation of component groups is direct except for "polyline flag" (code 70), which we split into two booleans, closed and plinegen. The properties repeated for each vertex are are represented by DxfLWPolylineVertex objects.
Primary reference is pages 81-82 of AutoCAD 2007 DXF Reference, available from the AutoDesk website.

    Description copied from interface: DxfStructure
    The type name of this structure. Generally this will be the same for all instances of the same implementing Java class, so a typical example might be:
```
 \/**
  * Type name of this structure. Always returns "POINT".
  * \@return "POINT"
  *\/
 public String getType() {
     return "POINT";
 }
 
```
    Specified by:
    
    getType in interface DxfStructure
    
    Specified by:
    
    getType in class DxfEntity
    
    Returns:
    type name of structure as defined in AutoCAD DXF specification
  - getGroups
```
public java.util.List<DxfGroup> getGroups(DxfVersion version)
```
    Description copied from interface: DxfStructure
    
    Get the internal state as DXFGroups.
    
    Specified by:
    
    getGroups in interface DxfStructure
    
    Overrides:
    
    getGroups in class DxfEntity
    
    Returns:
    list of groups containing the state data for this structure
  - setGroups
```
public void setGroups(java.util.List<DxfGroup> groups)
```
    Description copied from interface: DxfStructure
    
    Set the internal state based on the given groups.
    
    Specified by:
    
    setGroups in interface DxfStructure
    
    Overrides:
    
    setGroups in class DxfEntity
    
    Parameters:
    groups - list of groups containing data for this structure
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - getThickness
```
public double getThickness()
```
    Thickness, code 39, optional, default 0.
    
    Returns:
    thickness of the line
  - setThickness
```
public void setThickness(double newThickness)
```
  - isClosed
```
public boolean isClosed()
```
    True if polyline should be closed.
    This is derived from the 1-bit in group 70 (polyline flag).
    
    Returns:
    true if polyline is closed
  - setClosed
```
public void setClosed(boolean closed)
```
  - getConstantWidth
```
public double getConstantWidth()
```
    Constant width, code 43, optional, default 0.

    Sets the vertex list, replacing the old list. Makes a defensive copy, so you modifying the list supplied after calling this method will not also modify the list in this object.
    
    Parameters:
    vertices - new list of vertices
