Class RouteIteratorFactory

java.lang.Object

io.undertow.server.handlers.proxy.RouteIteratorFactory

public class RouteIteratorFactory
extends Object

Factory for route/affinity iterator parser. This implementation lazily parses routes while supporting strategies in RouteParsingStrategy including ranked routing. The iterator never creates new String instances but returns a CharSequence wrapper from the existing session ID.
