Modularity in Java: top level vs. nested classes

由 99封情书 提交于 2019-12-23 09:50:48
问题 The Java tutorials that I read, like to use nested classes to demonstrate a concept, a feature or use. This led me to initially implement a sample project I created just like that: Lots of nested classes in the main activity class. It works, but now I got a monstrous monolithic .java file. I find it somewhat inconvenient and I now intend to break to multiple .java files/classes. It occurred to me, however, that sometimes there may be reasons not to take classes out of their enclosing class.

AWS CloudFormation: Passing Values between Nested Stacks

由 拟墨画扇 提交于 2019-12-23 09:25:33
问题 More AWS questions! Ok, so the idea is one master template calls all the nested stacks. With help from here I figured out how to pass parameters from the master to the nested stacks. Now I am trying to figure out how to pass values from nested stacks to nested stacks. I believe this should be done via Exports and Imports, but I don't think I have this quite right. I'm not sure if it's my imports or exports that are wrong. The error I am getting is: No export named TestStack1-VpcStackID found.

问题 I'm trying to traverse a tree of nested of items using async.js. The traversal terminates after going through just one branch. var count=0; exports.buildFamily = function(item_id, mback){ var extendedFamily={}; exports.getItembyId(item_id, function(err, item){ extendedFamily=item; if(item.descendants){ extendedFamily.kids=[]; count=+item.descendants.length; console.log('outercount ' + count); async.eachSeries(item.descendants, function(item){ count-- console.log('item: ' + item) exports

问题 I have a 10x10 array representing 10 rows with 10 cells each. I want to draw a grid and set each cell's background-color according to the value in the array: a 0 value will be white and a 1 value will be black I've set up this CSS: .cell{ height: 20px; width: 20px; float: left; margin: 0; padding: 0; } .cell.live{ background-color: black; } .cell.dead { background-color: white; } I created a helper that will return 'live' or 'dead' according to the value in the array according to 2 arguments:

JQuery sortable nested sortable divs

由 旧城冷巷雨未停 提交于 2019-12-23 07:50:56
问题 This question has something to do with this one Nest jQuery UI sortables, but i couldn't solve my problem with it. Here's the problem: I have a main container that contains items, those items are divs that can be ungrouped items or groups, that contain other items. I can define new groups by dragging the .multiply-group div and then I can drag all the group at once. Here's the code: <body> <div class="multiply-container"> <div class="row multiply">Item 1</div> <div class="row multiply">Item 2

Nested blocks in Django templates

由 时光怂恿深爱的人放手 提交于 2019-12-23 06:48:10
问题 The master template in my Django app looks like this: {% block parent %} Some text... {% block child %} Default content here... {% endblock child %} ...some more text {% endblock parent %} Now, this template should be overwritten in a way that the child block is changed: {% extends "master.html" %} {% block child %} New content here... {% endblock child%} However, the rendering stays the same (printing "default content here..."). Have I missed something obvious or are nested blocks not

Python 3: How to check lists within lists with .count()

由 杀马特。学长 韩版系。学妹 提交于 2019-12-23 05:42:09
问题 The .count() doesn't check lists within other lists. How can I? FirstList = [ ['1', '2', '3'], ['4', '5', '6'], ['7', '8', '9'] ] While FirstList[0].count('1') returns 1. I want to check all of FirstList. How can I do this??? 回答1: Here are 3 possible solutions: given: xs = [['1', '2', '3'], ['4', '1', '1'], ['7', '8', '1']] [x.count('1') for x in xs] will return [1, 2, 1] and if you want to reduce that to a single value, use sum on that in turn: sum(x.count('1') for x in xs) which will, again

问题 I want to replace keys name of a dictionary by passing a mapping dict with a function that replace also nested keys.
