Method Detail

putWKSCoords

void putWKSCoords(_WKSPoint from,
                  _WKSPoint to)
                  throws IOException,
                         AutomationException

From and To become the new endpoints of this line. Any existing attributes are deleted.

Remarks

The from and to parameters are WKSPoint structures instead of Point objects. If you are not interested in using or preserving vertex attributes then PutWKSCoords and QueryWKSCoords can be a quicker way to modify and obtain the xy coordinates defining the line.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

from - A Structure: com.esri.arcgis.system._WKSPoint (A com.esri.arcgis.system._WKSPoint COM typedef) (in)

to - A Structure: com.esri.arcgis.system._WKSPoint (A com.esri.arcgis.system._WKSPoint COM typedef) (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryWKSCoords

void queryWKSCoords(_WKSPoint[] from,
                    _WKSPoint[] to)
                    throws IOException,
                           AutomationException

Returns the (x,y) coordinates of this line's endpoints.

Remarks

The from and to parameters are WKSPoint structures instead of Point objects. If you are not interested in using or preserving vertex attributes then PutWKSCoords and QueryWKSCoords can be a quicker way to modify and obtain the xy coordinates defining the line.
