public interface RequestSelectionTreeNode

Something that can have a CooldownCacheItem: Anything in the request selection tree, including the actual requests at the bottom (but ClientRequestSelector isn't actually a RequestSelectionTreeNode at the moment, the root is the priorities in the array on ClientRequestSelector; FIXME consistency with RGA.root etc).

Method Summary

Modifier and Type	Method and Description
void	clearWakeupTime(ClientContext context) When a request becomes fetchable, set all the wakeup times above it to 0.
RequestSelectionTreeNode	getParentGrabArray() Return the parent RequestSelectionTreeNode or null if it's not in the tree or is the root (e.g.
long	getWakeupTime(ClientContext context, long now) Unless this is a RandomGrabArrayItem, this will return the wakeup time for the subtree rooted at this node.
boolean	reduceWakeupTime(long wakeupTime, ClientContext context) If the current cooldown time is larger than the parameter, reduce it and recurse up the tree.

Method Detail

getParentGrabArray

RequestSelectionTreeNode getParentGrabArray()

Return the parent RequestSelectionTreeNode or null if it's not in the tree or is the root (e.g. priority classes are kept in an array on ClientRequestSelector).

getWakeupTime

long getWakeupTime(ClientContext context,
                   long now)

Unless this is a RandomGrabArrayItem, this will return the wakeup time for the subtree rooted at this node. For a RandomGrabArrayItem it returns the wakeup time for just that single request.

reduceWakeupTime

boolean reduceWakeupTime(long wakeupTime,
                         ClientContext context)

If the current cooldown time is larger than the parameter, reduce it and recurse up the tree. If we reach the root and wake it up, then wake up the scheduler. Returns true if anything changed.

clearWakeupTime

void clearWakeupTime(ClientContext context)

When a request becomes fetchable, set all the wakeup times above it to 0. Will recurse up the tree.
