This request would be parsed by the handler specified, and its priority can be downgraded to a minimum priority specified

Parameters:

r - request to fetch when dequeued

h - handler to be used to parse the request

p - initial priority of the request

pf - the minimum (floor) priority of this request

add

public void add(Request r,
                Handleable h,
                ai.preferred.venom.scheduler.BasicPriority p)

Description copied from interface: Scheduler

Adds a request to the queue

This request would be parsed by the handler specified, and its priority can be downgraded to the default minimum priority

Parameters:

r - request to fetch when dequeued

h - handler to be used to parse the request

p - initial priority of the request

add

public void add(Request r,
                Handleable h)
