All Implemented Interfaces:

DxfStructure

public class DxfPolyline
extends DxfEntity

A DXF POLYLINE entity.

A POLYLINE is a series of segments connecting vertices in 3D space. This is the older type of polyline in DXF; LWPOLYLINE has largely supplanted it.

POLYLINE can also be used to represent a number of other shapes, including various curves, polygons, and polyface meshes.

Primary reference is pages 89-91 of the AutoCAD 2007 DXF Reference, available from the AutoDesk website.

DxfPolyline

public DxfPolyline()

Method Detail

getType

public java.lang.String getType()

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
