The layer for defining, solving, and viewing network analysis results.

Remarks

NALayer is a composite layer that holds a reference to the NAContext and exposes the NAClasses within the NAContext as feature layers.

The NALayer behaves like any other composite layer within ArcGIS. Use ICompositeLayer and ICompositeLayer2 to access these properties.

It is possible to find an NALayer in ArcMap by enumerating through the layers in the table of contents and checking to see which ones implement the interface INALayer. You can also determine the NALayer currently selected in the network analyst window by asking the NAWindow for its ActiveAnalysis.

The entire NAContext, including the contents of the NAClasses, is persisted within the NALayer. If there are a lot of NALocationFeatures in the NAContext, the size of the NALayer saved in a map document and in a layer file could be large. The NATraversalResult is not persisted within the NALayer.

In ArcGIS for Server, starting a MapServer with multiple pooled objects that contain NALayers may cause some NALayers to not bind to their internal network dataset due to contention opening the network dataset. By default, the NALayer tries reconnecting to the network dataset for 60 seconds before returning a failure. If 60 seconds is not the appropriate amount of time for your server, create a registry key named "HKEY_LOCAL_MACHINE\Software\ESRI\ArcServer\NetworkAnalyst\OpenTimeout" of type DWORD with a decimal value between 0 and 600 that specifies the amount of time you want to try re-opening the network dataset before failing. A value of 600 means to keep trying to open the network analysis layer's network dataset for 10 minutes before failing. Setting it to 0 would indicate to fail immediately if it could not connect to the network dataset on its first attempt. This is only applicable to ArcGIS for Server MapServer objects containing NALayers.

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.

The CanCopy, CanDelete, and CanRename properties are meant to be used in conjunction with the Copy, Delete, and Rename methods and signify whether a dataset is supported by these methods. For example, you may not delete a network feature class nor can you use the Copy method on a Geodatabase feature class. To copy Geodatabase datasets, including feature classes, geometric networks, topologies, etc., use the IGeoDBDataTransfer interface.

The CanCopy method is supported by:

Remarks

The CanCopy, CanDelete, and CanRename properties are meant to be used in conjunction with the Copy, Delete, and Rename methods and signify whether a dataset is supported by these methods. For example, you may not delete or rename a network feature class nor can you use the Copy method on a Geodatabase feature class. To copy Geodatabase datasets, including feature classes, geometric networks, topologies, etc., use the IGeoDBDataTransfer interface.

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.

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.

identify

                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.
