The class Feature is the basic unit of which a FeatureSource is composed. A FeatureSource can be taken from a collection of Features stored in a ShapeFile, SQL Server 2008, Oracle, etc.A Feature is the basic data unit structure which is comprised of IDs that mark the identification of the Feature, a shape and a collection of data.

IsValid()

This method returns the results of some simple validity tests on the Feature.

This method is used primarily to ensure that a Feature is valid. The reason is, since this is a structure, we cannot control the main constructor that allows you to create a Feature in an invalid state – that state being one with no well-known binary at its core. If you use the constructure set provided, then the state should always be valid. This is a property you may want to check before you work with a Feature.

This method computes the area containing all of the points within a given distance from this feature. In this case, you will be using the rounded RoundedBufferCapStyle and the default 8 quadrant segments. The distance unit is determined by the distanceUnit argument. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

IsTopologicallyEqual(Feature)

This method returns if the current feature and the targetFeature are topologically equal.

Topologically equal means that the shapes are essentially the same. For example, let's say you have a line with two points, point A and point B. You also have another line that is made up of point A, point B and point C. Point A of line one shares the same vertex as point A of line two, and point B of line one shares the same vertex as point C of line two.
