public final class FastEngineMapper
extends java.lang.Object
implements ContainerListener, Lifecycle, Mapper, java.beans.PropertyChangeListener

Implementation of Mapper for an Engine, designed to process HTTP requests. This mapper selects an appropriate Host based on the server name included in the request.
