• N/A

• This method returns a user defined number of InternalFeatures that are closest to the TargetShape.

If there is a current transaction and it is marked as live, then the results will include any transaction Feature that applies. The implementation we provided create a small bounding box around the TargetShape and then queries the features inside of it. If we reach the number of items to find, then we measure the returned InternalFeatures to find the nearest. If we do not find enough records, we scale up the bounding box and try again. As you can see, this is not the most efficient method. If your underlying data provider exposes a more efficient way, we recommend you override the Core version of this method and implement it. The default implementation of GetFeaturesNearestCore uses the GetFeaturesInsideBoundingBoxCore method for speed. We strongly recommend that you provide your own implementation for this method that will be more efficient. When you override the GetFeaturesInsideBoundingBoxCore method, we recommend that you use any spatial indexes you have at your disposal to make this method as fast as possible. 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.

The implementation we provided create a small bounding box around the TargetShape and then queries the features inside of it. If we reach the number of items to find, then we measure the returned InternalFeatures to find the nearest. If we do not find enough records, we scale up the bounding box and try again. As you can see, this is not the most efficient method. If your underlying data provider exposes a more efficient way, we recommend you override the Core version of this method and implement it. The default implementation of GetFeaturesNearestCore uses the GetFeaturesInsideBoundingBoxCore method for speed. We strongly recommend that you provide your own implementation for this method that will be more efficient. When you override the GetFeaturesInsideBoundingBoxCore method, we recommend that you use any spatial indexes you have at your disposal to make this method as fast as possible. 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.

GetAllFeatures(IEnumerable<String>)

• N/A

• This method returns all of the InternalFeatures in the FeatureSource. It will return whatever is returned by the GetAllFeaturesCore method, along with any of the additions or subtractions made if you are in a transaction and that transaction is configured to be live. The main purpose of this method is to be the anchor of all of our default virtual implementations within this class. We as the framework developers wanted to provide you the user with as much default virtual implementation as possible. To do this, we needed a way to get access to all of the features. For example, let's say we want to create a default implementation for finding all of the InternalFeatures in a bounding box. Because this is an abstract class, we do not know the specifics of the underlying data or how its spatial indexes work. What we do know is that if we get all of the records, then we can brute-force the answer. In this way, if you inherited from this class and only implemented this one method, we can provide default implementations for virtually every other API. While this is nice for you the developer if you decide to create your own FeatureSource, it comes with a price: namely, it is very inefficient. In the example we just discussed (about finding all of the InternalFeatures in a bounding box), we would not want to look at every record to fulfil this method. Instead, we would want to override the GetFeaturesInsideBoundingBoxCore and implement specific code that would be faster. For example, in Oracle Spatial there is a specific SQL statement to perform this operation very quickly. The same holds true with other specific FeatureSource examples. Most default implementations in the FeatureSource call the GetFeaturesInsideBoundingBoxCore, which by default calls the GetAllFeaturesCore. It is our advice that if you create your own FeatureSource that you ALWAYS override the GetFeatureInsideBoundingBox. This will ensure that nearly every other API will operate efficiently. Please see the specific API to determine what method it uses. 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.
