Constructor Detail

MapServerRESTSubLayer

public MapServerRESTSubLayer(Object obj)
                      throws IOException

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

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

Throws:

IOException - if there are interop problems MapServerRESTSubLayer theMapServerRESTSubLayer = (MapServerRESTSubLayer) 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.

                 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

Specified by:

draw in interface ILayer2

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

                                             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.

Indicates if the current object draws using a filter.

Remarks

The UsesFilter property returns true when the object in question will draw with a filter. Drawing with a filter means means that an object that would normally draw as vector graphics will instead draw as raster. The UsesFilter property is particularly useful for detecting vector map layers that will be rasterized at time of print or export.

Indicates that features will be animated cumilatively.

Description

TimeDataCumulative is true when the data should be persist on the display as it ages. This is useful in settings where the new data "builds upon" historical data. For example when displaying the location of a wild animal, this property will cause the layer to display all of the historical locations for the animal, providing a good view of the animal's territory.

Returns recommended time interval to be used to animate this layer/ table.

Description

This property represents the time interval of the data used when rendering the layer. The time interval represents the minimum expected time between changes in the data. For example, when using weather imagery that is updated every 10 minutes, you would set the time interval to 10 minutes. When using census data that is recorded every year, the time interval would be set to 1 year. Note that this property is the value of the interval, and must be set along with the units for the time interval.

Description

The TimeOffset is used to display data at a different time on the timeline. This is for temporary purposes only. It can be useful for comparing data sets from different time period when you need to display the two sets of data together. For example, to visualize the growth pattern of two wild fires that happened in two different years, one of the layers can be given an offset that will cause it to appear as if the fire started at the same time as the other fire. In this way the growth patterns can be seen together, and compared.

                            throws IOException,
                                   AutomationException

Legend group at the specified index.

Product Availability

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

Specified by:

getLegendGroup in interface ILegendInfo

Parameters:

index - The index (in)

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getLegendItem

public ILegendItem getLegendItem()
                          throws IOException,
                                 AutomationException

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.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getLegendItem in interface ILegendInfo

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

isSymbolsAreGraduated

public boolean isSymbolsAreGraduated()
                              throws IOException,
                                     AutomationException

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.
