public abstract class UriPrecedencePolicy
extends Object
implements Serializable

Superclass for URI precedence policies, which set a integer precedence value on individual URIs when they are first submitted to a frontier for scheduling. A URI's precedence directly affects where it lands in an individual URI queue, but does not affect a queue's precedence relative to other queues *unless* a queue-precedencence-policy that consults URI precedence values is chosen.
