                                  AutomationException

Supported draw phases.

Remarks

Indicates the draw phases supported by the layer (esriDPGeography, esriDPAnnotation, esriDPSelection, or any combination of the three). The supported draw phases are defined by esriDrawPhase. When multiple draw phases are supported, the sum of the constants is used. For example, if SupportedDrawPhases = 3 then the layer supports drawing in the geography and annotation phases.

Product Availability

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

                                     AutomationException

Spatial reference for the layer.

Remarks

This property is only used for map display, setting this property does not change the spatial reference of the layer's underlying data. The ArcGIS framework uses this property to pass the spatial reference from the map to the layer in order to support on-the-fly projection.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

setSpatialReferenceByRef in interface ILayer

Parameters:

rhs1 - A reference to a com.esri.arcgis.geometry.ISpatialReference (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

draw

public void draw(int drawPhase,
                 IDisplay display,
                 ITrackCancel trackCancel)
          throws IOException,
                 AutomationException

Draws the layer to the specified display for the given draw phase.

Remarks

This method draws the layer to the Display for the specified DrawPhase. Use the TrackCancel object to allow the drawing of the layer to be interrupted by the user.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

draw in interface ILayer

Parameters:

drawPhase - A com.esri.arcgis.system.esriDrawPhase constant (in)

display - A reference to a com.esri.arcgis.display.IDisplay (in)

trackCancel - A reference to a com.esri.arcgis.system.ITrackCancel (in)

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.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getExtent in interface IGeoDataset

Returns:

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

Optional. Defines legend formatting for layer rendered with this object.

Remarks

Layer or renderer legend information is further formatted for display in ArcMap legends. A renderer can override this formatting by returning a LegendItem for this property. ESRI renderers typically do not return anything for this property. With this configuration, legend formatting becomes a user or developer choice on the legend object.

Indicates if symbols are graduated.

Description

Indicates whether the symbols used for a layer or renderer's legend vary by size.

Remarks

For example the proportional symbol renderer returns True for this property.

You can use this property to distinguish between a layer symbolized with graduated color or graduated symbol type layer symbology. Both of these symbolizations use a ClassBreaksRenderer, but only a graduated symbol symbolization will return True for this property.

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.
