![]() Specified by: size in interface Linear Specified by: size in interface Structure Returns: number of elements in queue. Int size() Returns the number of elements in the queue. Postcondition: returns true if and only if the queue is empty Specified by: empty in interface Linear Returns: True iff the queue is empty. peek() Fetch the value at the head of the queue.īoolean empty() Returns true iff the queue is empty. Precondition: the queue is not empty Postcondition: the element at the head of the queue is returned Specified by: get in interface Linear Returns: Reference to the first value of the queue. get() Fetch the value at the head of the queue. Returns: Reference to the first value of the queue. getFirst() Fetch the value at the head of the queue. Precondition: the queue is not empty Postcondition: the head of the queue is removed and returned Returns: The value removed from the queue. dequeue() Remove a value from the head of the queue. See Also: dequeue() Precondition: the queue is not empty Postcondition: the head of the queue is removed and returned Specified by: remove in interface Linear Returns: The value actually removed. remove() Remove a value form the head of the queue. Postcondition: the value is added to the tail of the structure Parameters: value - The value to be added. Void enqueue( value) Add a value to the tail of the queue. See Also: enqueue() Postcondition: the value is added to the tail of the structure Specified by: add in interface Linear Specified by: add in interface Structure Parameters: value - The value added. Void add( value) Add a value to the tail of the queue. StructureĬlear, contains, elements, isEmpty, iterator, remove, values ![]() Methods inherited from interface structure.

Nothing says you can't use yet another loop to do that processing.SUMMARY: NESTED | FIELD | CONSTR | METHOD But these processing modules are time-consuming and memory-consuming,the buffer will overflow.If you have any advises,please contact me. Enqueue and Dequeue tend to be operations on a queue, a data structure that does exactly what it sounds like it does. You may think that I can put the rest processing modules into the dequeue loop. Dequeue: The full name of the dequeue is a double-ended queue. ![]() Thirdly, like the number part after the dequence loop, there are still some processing modules which need all the processing result arrays generated in the dequence loop.So here I put a number control to illustrate. Enqueue Dequeue When you insert an element in the queue, that process is called Enqueue, and when you remove an element from the queue, that process is called Dequeue. This will ensure you have processed all of your wrote: When the consumer sees that command, it knows to stop. That's why I said to put a command of some sort into your queue when the producer loop is done. So I wait all the elements dequeue, then stop the dequeue loop. Secondly, I have to stop the enqueue loop because there may be some element wait in enqueue loop. If there isn't data in the queue, then it sleeps until there is wrote: ![]() The consumer loop will iterate based on when data is in the queue. Your producer loop should run at whatever it needs to, based on how fast you are aquiring data from the DAQ. In order to have the data acquisition (the enqueue loop) and the data processing(the dequeue )can be synchronous, I have the enqueue and dequeue the same rate.Īgain, that doesn't make much sense. ![]()
