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 set of properties for the dataset.

Description

The PropertySet property is used to return any additional intrinsic properties (but not metadata properties) that may apply to the dataset. One use of this property is to distinguish between the types of File Geodatabase datafile formats. If called on a Feature Class or Table in a File Geodatabase the Datafile Format property can either be esriFGDBStandardDatafile or esriFGDBCompressedDatafile.

Most datasets do not implement this property and will either raise an error or return a null value if it's called. There are a handful of exceptions that will return property sets; these include the datasets from file geodatabases (as mentioned above) and coverages.

Remarks

Examples of intrinsic properties for which explicit methods exist include the SpatialReference and the Extent methods available on the IGeoDataset interface. In most cases this PropertySet will be empty.

IDataset::PropertySet is not supported for Graph objects such as a Geometric Network.

getTimeInterval

public double getTimeInterval()
                       throws IOException,
                              AutomationException

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.

getTimeOffset

public double getTimeOffset()
                     throws IOException,
                            AutomationException

Returns time offset that needs to be applied to the data for drawing.

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.

getSpatialReference

public ISpatialReference getSpatialReference()

                                             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.

The red box represents the IGeoDataset extent

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.

The red box represents the IGeoDataset extent after some of the features have been deleted

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.

The red box represents the IGeoDataset extent after it has been updated

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

Indicates if the receiver can apply the given object at any given time.

Remarks

Applies indicates whether the specified object can be applied to the current object. For instance, we might want to ask our CircleElement whether a Color object applies to it. If it does, then we can use the Apply method to update our CircleElement with the new Color object.

CanApply differs from Applies in that it is a check for the editability of the object at any given time. Applies indicates whether an object can be applied at all, while CanApply indicates whether an object can be applied at that particular moment.

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.

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.
