Class RubberPolygon

java.lang.Object
  com.esri.arcgis.display.RubberPolygon

All Implemented Interfaces:

IRubberBand, IRubberBand2, com.esri.arcgis.interop.RemoteObjRef, Serializable

public class RubberPolygon
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IRubberBand, IRubberBand2

Rubberbanding class for polygons.

Remarks

RubberPolygon implements the IRubberBand interface, which contains the TrackNew and TrackExisting methods. Use the TrackNew method to digitize a new polygon on the map. Use the TrackExisting method to track existing polygons. Both methods are commonly used in the MouseDown event.

Calling ITopologicalOperator::Simplify on the digitized polygon will ensure that it is topologically correct.

Constructor Detail

RubberPolygon

public RubberPolygon()
              throws IOException,
                     UnknownHostException

Constructs a RubberPolygon using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

RubberPolygon

public RubberPolygon(Object obj)
              throws IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
RubberPolygon theRubberPolygon = (RubberPolygon) obj;

Construct a RubberPolygon using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to RubberPolygon.

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object
