Interface IFeatures

All Known Implementing Classes:

Features

public interface IFeatures

Interface for an features. Features gives access to feature sets, which is a way to mark events so they can be filtered on later on. Typically a feature set is implemented using a bit set on the underlying event, which makes it it very cheap to check and filter out if it's been marked. It's however possible to implement IFeatureSet using HashSet or disk/database providers that wants to hold on to very large number of events.
