So verb, verbs that clearly express an action that + +5 +00:00:10,099 --> 00:00:13,580 +can tell me that, you know, what, for example, an item could do, 'kay? + +6 +00:00:13,580 --> 00:00:13,820 +>> Okay? + +7 +00:00:13,820 --> 00:00:16,620 +>> Not the verbs that represent, for example, relationships, 'kay? + +8 +00:00:16,620 --> 00:00:17,076 +>> Okay. + +9 +00:00:17,076 --> 00:00:19,080 +>> So, and the, there, and the ones + +10 +00:00:19,080 --> 00:00:22,020 +that I've identified und, underlined here actually, I, + +11 +00:00:22,020 --> 00:00:26,158 +I underlined complete sentences so that you kind of we can look at the verbs in + +12 +00:00:26,158 --> 00:00:29,150 +in context. And the first one is this + +13 +00:00:29,150 --> 00:00:30,850 +sentence that says that the library may need + +14 +00:00:30,850 --> 00:00:33,190 +to know or to calculate the items a + +15 +00:00:33,190 --> 00:00:35,790 +patron has checked out, when they are due, and + +16 +00:00:35,790 --> 00:00:38,860 +any outstanding overdue fines. So I, I will + +17 +00:00:38,860 --> 00:00:41,430 +imagine that this is representing a situation in + +18 +00:00:41,430 --> 00:00:44,224 +which you bring up a patron's record and + +19 +00:00:44,224 --> 00:00:46,131 +you start looking up this information. Is that [CROSSTALK] + +20 +00:00:46,131 --> 00:00:50,970 +>> The, the patron often wants to know what they have currently checked out. + +21 +00:00:50,970 --> 00:00:51,044 +>> Oh, + +22 +00:00:51,044 --> 00:00:51,282 +alright. + +23 +00:00:51,282 --> 00:00:53,260 +>> Or when are their due or how much they're owed or. + +24 +00:00:53,260 --> 00:00:55,100 +>> Oh, in fact, and then now that you mentioned it, + +25 +00:00:55,100 --> 00:00:57,500 +I think you sent me. One of the scenarios you sent + +26 +00:00:57,500 --> 00:00:59,400 +me had to do with that, right, with the patron coming + +27 +00:00:59,400 --> 00:01:01,930 +in and asking for this information. So yeah, and it makes + +28 +00:01:01,930 --> 00:01:05,025 +a lot of sense. So what I'm going to do, I'm going to + +29 +00:01:05,025 --> 00:01:10,520 +model this by adding this three operations to the patron method. + +30 +00:01:10,520 --> 00:01:13,410 +The first one, I'm going to call, itemsCheckedOut and, basically, it's an + +31 +00:01:13,410 --> 00:01:16,520 +operation, but you don't need to, you know, understand the implementation + +32 +00:01:16,520 --> 00:01:18,820 +details, but when you call this operation, it will + +33 +00:01:18,820 --> 00:01:21,770 +give you back exactly this information, so the items + +34 +00:01:21,770 --> 00:01:23,864 +that are checked out by that patron. The second + +35 +00:01:23,864 --> 00:01:25,965 +one, I'm going to call it whenDue. That will tell you + +36 +00:01:25,965 --> 00:01:29,080 +basically when a, when an item is due. And + +37 +00:01:29,080 --> 00:01:32,550 +the third one is going to be called the outstandingOverdueFines and, + +38 +00:01:32,550 --> 00:01:34,510 +you know, as the name says, it's going to tell + +39 +00:01:34,510 --> 00:01:36,860 +you what are the outstanding overdue fines for that patron. + +40 +00:01:36,860 --> 00:01:37,300 +>> Okay. + +41 +00:01:37,300 --> 00:01:39,306 +>> And as you might notice I mean, + +42 +00:01:39,306 --> 00:01:41,843 +I, I'm going to separate the, the, the attributes + +43 +00:01:41,843 --> 00:01:44,085 +from the operations by having a separate kind + +44 +00:01:44,085 --> 00:01:46,386 +of subrectangle so, in this way, it's clear + +45 +00:01:46,386 --> 00:01:48,274 +what is attribute and what is, what is + +46 +00:01:48,274 --> 00:01:51,000 +an attribute and what's an, what's an operation. + +47 +00:01:51,000 --> 00:01:51,420 +>> Gotcha. + +48 +00:01:51,420 --> 00:01:57,540 +>> And let me see then. Okay, for the + +49 +00:01:57,540 --> 00:02:00,040 +second one you can see that that patron can check + +50 +00:02:00,040 --> 00:02:02,990 +out books and audio visual materials. So I guess, + +51 +00:02:02,990 --> 00:02:06,880 +similarly you, you build kind of the record for a patron. + +52 +00:02:06,880 --> 00:02:09,150 +The patron will give you an item and you will record + +53 +00:02:09,150 --> 00:02:11,020 +the fact that the patron is kind of checking it out. + +54 +00:02:11,020 --> 00:02:15,730 +>> Right. And is that operation related to this, + +55 +00:02:15,730 --> 00:02:18,150 +the checked out attribute that we did a minute ago? + +56 +00:02:18,150 --> 00:02:21,495 +>> It is actually because what will happen then again, you know, if we jump + +57 +00:02:21,495 --> 00:02:24,975 +ahead a little bit would be that every time you invoke this operation. So I'm + +58 +00:02:24,975 --> 00:02:26,810 +going to represent this as a checkOut operation + +59 +00:02:26,810 --> 00:02:28,896 +for the patron. Every time you invoke this, + +60 +00:02:28,896 --> 00:02:31,920 +you will also have to say something about the item and so we will also + +61 +00:02:31,920 --> 00:02:35,700 +flip kind of that that, that build information in the, in the, in the item. + +62 +00:02:35,700 --> 00:02:36,904 +>> Okay. + +63 +00:02:36,904 --> 00:02:39,680 +>> Mm, 'kay? And, and finally, here, I can see that + +64 +00:02:39,680 --> 00:02:42,660 +a patron can request a book or an audio video item Is + +65 +00:02:42,660 --> 00:02:46,240 +not currently in. So I guess this is referring to items that + +66 +00:02:46,240 --> 00:02:48,980 +are already checked out but for which there is interest. Is that? + +67 +00:02:48,980 --> 00:02:54,770 +>> Right. So, particularly, the popular items the patrons want to get on + +68 +00:02:54,770 --> 00:02:57,140 +the list so that they get notified when it comes back in and. + +69 +00:02:57,140 --> 00:02:57,204 +>> Oh. + +70 +00:02:57,204 --> 00:02:57,730 +>> And check it out. + +71 +00:02:57,730 --> 00:03:00,570 +>> I see. I see. Okay. Then I'm going to do + +72 +00:03:00,570 --> 00:03:04,400 +the same thing here. I'm, I'm going to add this method, + +73 +00:03:04,400 --> 00:03:08,510 +which I'm going to call request and I'm going to put it + +74 +00:03:08,510 --> 00:03:11,340 +here in the list of the methods in the list. + +75 +00:03:11,340 --> 00:03:11,450 +>> Okay. + +76 +00:03:11,450 --> 00:03:12,810 +>> Of operations for the, for the patron, okay? + -- cgit 1.4.1
