All Implemented Interfaces:

DxfStructure

public class DxfVertex
extends DxfEntity

A DXF VERTEX entity.

A VERTEX is a point in a POLYLINE. Despite the name, POLYLINEs and their VERTEXes can represent all kinds of shapes, including curves, polygons and polyface meshes.

Primary reference is pages 109-110 of the AutoCAD 2007 DXF Reference, available from the AutoDesk website.

DxfVertex

public DxfVertex()

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

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
