Method Detail

constructAverage

void constructAverage(IPointCollection points,
                      int attributeType)
                      throws IOException,
                             AutomationException

Constructs the geometric average of the input point collection. Optionally uses the specified attribute as a source of weights on the locations of the points.

Remarks

If attributeType is esriAttributeNone then the average point location is computed; otherwise the attribute specified by attributeType serves as a weight. Points whose weight attribute is NaN are ignored (a weight of 0 has a similar affect). The resulting point will have the (weighted) average for all their attributes. However this does not apply to ID's; no average is calculated for them in any case; but thay can be used as weight.

Only the following attributeType values are permitted: esriAttributeNone, esriAttributeZ, esriAttributeM, esriAttributeID.

Supported Platforms

Windows, Solaris, Linux

Parameters:

points - A reference to a com.esri.arcgis.geometry.IPointCollection (in)

attributeType - A com.esri.arcgis.geometry.esriGeometryAttributes constant (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
