java.lang.Object

org.gvsig.dwg.lib.DwgFile

public class DwgFile
extends java.lang.Object

The DwgFile class provides a revision-neutral interface for reading and handling DWG files Reading methods are useful for reading DWG files, and handling methods like calculateDwgPolylines() are useful for handling more complex objects in the DWG file

                      java.lang.Object value)

getHeader

public java.lang.Object getHeader(java.lang.String key)

addDwgLayer

protected void addDwgLayer(DwgLayer dwgLayer)

getDwgLayer

public DwgLayer getDwgLayer(DwgObject entity)

getDwgSuperEntity

public DwgObject getDwgSuperEntity(DwgObject entity)

getLayerName

public java.lang.String getLayerName(DwgObject entity)

getColorByLayer

public int getColorByLayer(DwgObject entity)

Returns the color of the layer of a DWG object

Parameters:

entity - DWG object which we want to know its layer color

Returns:

int Layer color of the DWG object in the Autocad color code

calculateGisModelDwgPolylines

public void calculateGisModelDwgPolylines()

Configure the geometry of the polylines in a DWG file from the vertex list in this DWG file. This geometry is given by an array of Points. Besides, manage closed polylines and polylines with bulges in a GIS Data model. It means that the arcs of the polylines will be done through a set of points and a distance between these points.

blockManagement2

public void blockManagement2()

Configure the geometry of the polylines in a DWG file from the vertex list in this DWG file. This geometry is given by an array of Points Besides, manage closed polylines and polylines with bulges in a GIS Data model. It means that the arcs of the polylines will be done through a curvature parameter called bulge associated with the points of the polyline.

manageInsert2

public void manageInsert2(java.awt.geom.Point2D insPoint,
                          double[] scale,
                          double rot,
                          int bHandle,
                          java.util.List dwgObjectsWithoutBlocks,
                          java.util.Map handleObjectsWithoutBlocks)

getIndexOf

public int getIndexOf(DwgObject dwgObject)
