Queue -- Click element; stores packets in a FIFO queue
Ports: 1 input, 1-2 outputs
Package: standard (core)
Stores incoming packets in a first-in-first-out queue. Drops incoming packets if the queue already holds CAPACITY packets. The default for CAPACITY is 1000. Queue notifies interested parties when it becomes empty and when a formerly-empty queue receives a packet. The empty notification takes place some time after the queue goes empty, to prevent thrashing for queues that hover around 1 or 2 packets long. This behavior is the same as that of NotifierQueue. (See QuickNoteQueue for an alternative.) Queue additionally notifies interested parties that it is non-full, and when a formerly-full queue gains some free space. In all respects but notification, Queue behaves exactly like SimpleQueue. You may also use the old element name "FullNoteQueue". Multithreaded Click note: Queue is designed to be used in an environment with at most one concurrent pusher and at most one concurrent puller. Thus, at most one thread pushes to the Queue at a time and at most one thread pulls from the Queue at a time. Different threads can push to and pull from the Queue concurrently, however. See ThreadSafeQueue for a queue that can support multiple concurrent pushers and pullers.
