This method will add an item to the FeatureCache system by passing a WorldExtent as “Key” and a collection of features as its corresponding cached features.

This method is the concrete wrapper for the virtual method AddCore. It will return whatever is returned by the AddCore method. To determine what the default implementation of the abstract AddCore method is, please see the documentation for it. 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.
