Method Summary

Modifier and Type	Method and Description
long	checkRecentlyFailed(Key key, boolean realTime) If we are fairly sure we'd like to send this request, we need to route it and determine whether it would be rejected with RecentlyFailed.
boolean	hasInsert(SendableRequestItemKey token) Is this request:token pair being executed? FIXME this should be tracked by the inserter itself.
boolean	hasKey(Key key, BaseSendableGet getterWaiting) Is this key currently being fetched locally? LOCKING: This should be safe just about anywhere, the lock protecting it is always taken last.

Method Detail

checkRecentlyFailed

long checkRecentlyFailed(Key key,
                         boolean realTime)

If we are fairly sure we'd like to send this request, we need to route it and determine whether it would be rejected with RecentlyFailed. Note that this method is fairly heavyweight and may involve locking PeerNode's and possibly other things.

Parameters:

key - The key to check.

Returns:

0 if the request can be sent, otherwise the time at which it can be sent. The caller must incorporate this into the relevant cooldown structures to avoid an expensive recomputation.

hasKey

boolean hasKey(Key key,
               BaseSendableGet getterWaiting)

Is this key currently being fetched locally? LOCKING: This should be safe just about anywhere, the lock protecting it is always taken last.

hasInsert

boolean hasInsert(SendableRequestItemKey token)

Is this request:token pair being executed? FIXME this should be tracked by the inserter itself.
