PODesign Question - OO food application
text
Body
copied!<p>Say I have a number of usercontrols, each usercontrol inside a tabitem, inside a window.</p> <p>For example, let say this is a food collection application. Then we have tabs Fruit, Vegetables and Snacks. Each tab will show a list of food of that subject, and allow the user to add, delete, modify the food in each section. The food is stored in seperate textfiles, i.e. Fruit.txt, Vegetable.txt, Snack.txt</p> <p>The actual text files might look something like this (vegetable.txt):</p> <pre><code>Name Carbs Fat Eggplant 2 1.1 Cucumber 3 0.5 etc </code></pre> <p>Now this is a large list and there is a load method which pulls all the vegetables out into a List</p> <p>The question I have is this loadVegetables method is in the code behind file, and I end up repeating this load method all over the place, because I have another of other screens like ReviewAllFood, AddVegetable, etc. along with all the other load methods for fruit and snacks.</p> <p>This is more of a design question, I'm wondering how I set this up to not repeat this code. I could have a VegetableManager (or something) class where the load method is, but does this actually mean less repeated code? Then in each screen I have to create object of VegetableManager and call its load method anyway. So I guess efficiency wise its no better, but I do achieve a better design.</p> <p>I think I'm missing something here. It's been a while since I studied cohesion and coupling and I think i'm confusing myself with these concepts at the moment. Appreciate if someone could suggest a design for this situation and explain why they chose it and why its better than how i'm doing it at the moment.</p> <p>Thanks for reading.</p>
