Example
Remarks
Where the layer is extractable, this property provides information about the layer to be extracted. Extracting is the process of clipping features and downloading the features in layers in a zip file. See the Extractor class for more on extracting map layers.
A known issue is that layers may be extractable even when ExtractInfo is null (Nothing). If the ArcXML configuration file for the map service has at least one layer with the EXTRACT extension tag, then every feature layer will be extractable. Feature layers with the EXTRACT tag in the configuration file will have a valid ExtractInfo object. Feature layers without this tag in the configuration file will have no ExtractInfo object, but can still be extracted. Those layers will use defaults for extracted file name, fields, code page, and clipping of features.
