Constructor Detail

WMSLayer

public WMSLayer(Object obj)
         throws IOException

Construct a WMSLayer using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to WMSLayer.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
WMSLayer o = (WMSLayer)obj; // will not work

WMSLayer o = new WMSLayer(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems WMSLayer theWMSLayer = (WMSLayer) obj;

Remarks

The valid property indicates if the layer is currently valid. Layers that reference feature classes are valid when they hold a reference to a valid feature class. The property does not however validate the integrity of the feature classes reference to the database. Therefore, in rare situations if a datasource is removed after a layer is initialized, the layer will report itself as valid but query attempts to the data source will error due to the lack of underlying data.

identify

public IArray identify(IGeometry pGeom)
                throws IOException,
                       AutomationException

Identifies objects at the specified location.

Remarks

When the IIdentify interface is on a map layer, the Identify method returns an array of FeatureIdentifyObject objects.

On a FeatureIdentifyObject, you can do a QI to the IIdentifyObj interface to get more information about the identified feature. The IIdentifyObj interface returns the window handle, layer, and name of the feature; it has methods to flash the feature in the display and to display a context menu at the Identify location.

This method performs an identify operation with the provided geometry. When identifying layers, typically a small envelope is passed in rather than a point to account for differences in the precision of the display and the feature geometry.
