Constructor Detail

BasemapSubLayer

public BasemapSubLayer(Object obj)
                throws IOException

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

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

Throws:

IOException - if there are interop problems BasemapSubLayer theBasemapSubLayer = (BasemapSubLayer) obj;

Method Detail

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

getLayer

public ILayer getLayer()
                throws IOException,
                       AutomationException

Gets the contained layer.

Product Availability

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

Specified by:

getLayer in interface IBasemapSubLayer

Returns:

A reference to a com.esri.arcgis.carto.ILayer

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getConversionStatus

public int getConversionStatus()
                        throws IOException,
                               AutomationException

Indicates the conversion status of a given layer.

Product Availability

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

Specified by:

getConversionStatus in interface IBasemapSubLayer

Returns:

A com.esri.arcgis.carto.esriConversionStatus constant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSpatialReference

public ISpatialReference getSpatialReference()
                                      throws IOException,
                                             AutomationException

The spatial reference of the GeoDataset.

Remarks

This property is read only. For layers, when the first layer is added to ArcMap, its spatial reference is read by this property, and the map is set to this spatial reference.

Instances of the esriCarto.GroupLayer class will return null for this property, as a group layer can contain multiple datasets with different spatial references.

Modifications to a spatial reference returned by this property will not be persisted. To modify the spatial reference of a dataset, the IGeoDatasetSchemaEdit and IGeoDatasetSchemaEdit2 interfaces should be used.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getSpatialReference in interface IGeoDataset

Returns:

A reference to a com.esri.arcgis.geometry.ISpatialReference

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getExtent

public IEnvelope getExtent()
                    throws IOException,
                           AutomationException

The extent of the GeoDataset.

Remarks

The IGeoDataset::Extent property returns an envelope representing the maximum extent of data which has been stored in the dataset.

Consider the following scenario. A new feature class has features added to it. The IGeoDataset::Extent is then requested and an envelope is returned. The extents of the envelope returned are represented by the red box in the image below.

If a portion of the features were then deleted and the extent is again requested an envelope with the exact same extents as during the first request would be returned (see image below). This is because the deletion of features does not shrink the extent. However all additions of features outside the red box would increase the envelope returned to encompass the newly added features.

If you would like to update the IGeoDataset::Extent property to reflect the current features in your dataset please see IFeatureClassManage::UpdateExtent (also see IFeatureClassLoad). In the image below the extent has been updated and a new envelope is being returned.

ESRI's GroupLayer implements this property differently from most other layer coclasses. When you instantiate a new GroupLayer, this property will return a valid envelope with zero height and width. With most other newly instantiated layers (for example FeatureLayer, RasterLayer, TinLayer), this property initally returns Nothing.

                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.
