While they do the job basically, we had a desire for years to get something better. New XML Plugin for Xojo For 20 years we used the built-in XML classes in Xojo. Since the conference hotel allows you to cancel, it may be good to reserve a room and later rebook it or cancel, when you find a lower rate. Or maybe you like to share a room when traveling with your colleague? You can either stay in the conference hotel ($269 USD/night) or maybe better get a cheaper hotel outside and drive daily to downtown for the conference. I bet you'll enjoy it! Be sure sure to stay the night on Tuesday, so you can enjoy the dinner and travel home a day later. Yes, instead of lots of sessions in a ballroom, Dana organized something different this time. Two days of conference follows with a special developer adventure on the second day. You may want to use the weekend to come to Nashville earlier to enjoy the city and then join the get-together on Sunday evening. Please reserve the days from 18th to 21st September in your calendar. Xojo Developer Retreat 2022, 19th and 20th September 2022. Queue_MTC is a fast queue class for Xojo.Just one month till the XDC Developer Retreat 2022 starts in Nashville: ( Dequeue is a first-in-first-out method while Pop is a last-in-first-out method.) It will work like a Variant array that references "items" instead of "rows", e.g., RemoteItemAt, and has an Enqueue method rather than AddRow and a Dequeue method in addition to Pop. In all cases, Queue_MTC was designed to be faster than using a plain array. Open the Harness project and copy Queue_MTC into your project, or drag the Queue_MTC.xojo_code file into your project. Return and remove the first item in the queue (FIFO) MethodĪ new instance as a shallow copy of the given Queue_MTC Queue_MTC will act like an ordinary Variant array, with some differences. Returns a Variant array of the current items Return the index of the given item or -1 if not found Return and remove the last item in the queue (LIFO) Individual items may be referenced like an array, e.g., q(1) = true and v = q(10). Var queue as new Queue_MTC queue.Enqueue( "hi" ) queue.Enqueue( 3 ) var s as string = queue.Dequeue // "hi" var i as integer = queue.Dequeue // 3 queue.Enqueue( 1 ) queue.Enqueue( 2 ) if queue( 0 ) = 1 then // it is end if i = queue.Dequeue // 1 if queue( 0 ) = 2 then // it is end if queue.RemoveAllItems queue.Enqueue( 0 ) queue.Enqueue( 1 ) queue.Enqueue( 2 ) queue.Enqueue( 3 ) queue.Enqueue( 4 ) call queue.Dequeue // 0 call queue.Pop // 4 queue.RemoveItemAt( 2 ) // Now 1, 2 if queue.Count = 2 then // it is end if i = queue.IndexOf( 2 ) // will be 1 var arr() as variant = queue.ToArray if arr.LastRowIndex = queue.LastItemIndex then // it does end if Behind The Scenes loop to cycle through every element of the queue.
Queue_MTC achieves its speed gains by rarely modifying its internal Variant array. It starts with an array of a known size and keeps doubling it when more space is needed. It tracks your items through internal indexes that get updated whenever items are queued or de-queued, and only periodically resizes the array during idle time to keep it from getting out of control. You can compare the speed of Queue_MTC vs. an ordinary Variant array by running the "Timing" unit tests in the Harness project. This was created by Kem Tekinay of MacTechnologies Consulting.
