| EnqueuePredicateIF | | public interface EnqueuePredicateIF (Code) | | Enqueue predicates allow users to specify a method that will
'screen' elements being enqueued onto a sink, either accepting or
rejecting them. This mechanism can be used to implement many interesting
load-conditioning policies, for example, simple thresholding, rate
control, credit-based flow control, and so forth. Note that the enqueue
predicate runs in the context of the caller of enqueue(), which
means it must be simple and fast.
