Class RubberLine

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

All Implemented Interfaces:

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

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

Rubberbanding class for lines.

Description

RubberLine returns an IGeometry, but may be used as an IPolyLine.

Remarks

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

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

Constructor Detail

RubberLine

public RubberLine()
           throws IOException,
                  UnknownHostException

Constructs a RubberLine using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

RubberLine

public RubberLine(Object obj)
           throws IOException

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

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

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

trackNew
