How to use enum with grouping and subgrouping hierarchy/nesting

由 陌路散爱 提交于 2019-12-09 04:35:39
问题 I have one enum 'class' called Example as follows: enum Example { //enums belonging to group A: enumA1, enumA2, enumA3, //enums belonging to group B: enumB1, enumB2, enumB3, //enums belonging to group C: enumC1, enumC2, enumC3; } It's important for my project they all enums I work with belong to Example (since this is an argument in a constructor of a class). How do I use enum hierarchy/nesting in order to achieve the following: A method that tests whether an enum is of group A, B or C. For

nesting too deep in JSON… should I switch to XML?

由 主宰稳场 提交于 2019-12-09 03:39:07
问题 I am getting a JSONException complaining about a very deep nesting (more than 30). I know that the value is hardcoded in JSONWriter. what best can I do? use another library without this restriction if such thing exists? switch to XML? UPDATE: I am serializing a labeled tree structure into JSON. So starting with root, each node is nesting its children which in turn nesting theirs... {"type":"n1","links":[{"label":"l1","target":{"type":"n2","links":[{"label":"l2","target":{ ...}}]}}]} I might

Append elements to nested list in TCL

由 江枫思渺然 提交于 2019-12-09 03:34:19
问题 I want to dynamically add elements to nested lists. Consider the following example: set super_list {} lappend super_list {00 01 02} lappend super_list {10 11 12} lappend super_list {20 21} results in: super_list = {00 01 02} {10 11 12} {20 21} [lindex $super_list 0] = {00 01 02} [lindex $super_list 1] = {10 11 12} [lindex $super_list 2] = {20 21} How do I append another value (e.g. 22) to [lindex $super_list 2]? lappend [lindex $super_list 2] 22 does not work! The only workaround I could

Flask/Jinja2 - Iterating over nested dictionaries

由 我只是一个虾纸丫 提交于 2019-12-08 19:00:29
I'm trying to display the contents and structure of a dictionary in the form of a bunch of nested un-ordered lists. The data that I've managed to pull together looks like this, {'.': {'walk.py': None, 'what.html': None, 'misc': {}, 'orders': {'order1.html': None, 'more': {'stuff.html': None}}}} which represents this directory tree, .: misc/ orders/ walk.py what.html ./misc: ./orders: more/ order1.html ./orders/more: stuff.html How would I go about iterating over this using the Jinja2 Syntax? Is there a better way go about doing this? Thanks in advace. EDIT: I feel stupid. After searching for a

How to initialize nested dictionaries in Python

由 时间秒杀一切 提交于 2019-12-08 15:59:00
问题 I'm using Python v2.7 dictionaries, nested one inside another like this: def example(format_str, year, value): format_to_year_to_value_dict = {} # In the actual code there are many format_str and year values, # not just the one inserted here. if not format_str in format_to_year_to_value_dict: format_to_year_to_value_dict[format_str] = {} format_to_year_to_value_dict[format_str][year] = value It seems a bit clumsy to initialize the first level dictionary with an empty dictionary before

css/jquery: scroll limit with nested scoll and hidden scroll bar

由 瘦欲@ 提交于 2019-12-08 14:25:57
问题 Here is an example of what I want to do: http://jsfiddle.net/bnsadku9/1/ I have a fixed header that is coverred by a div below when scrolled. At a fixed height the scroll stops and the div continues to scroll inside itself (to reveal the content). There are are some minor problems with my current implementation: 1) I don't want to inner scroll bar to show up. I tried playing aroung with position and margin instead of overflow:scroll or with switching the z-position but that didn't work or hid

Logic behind printing pyramid shape using nested for loops in Java

由 我只是一个虾纸丫 提交于 2019-12-08 14:24:15
问题 I have modified sample code around to get the output I was looking for, but I do not understand the logic behind the nested for-loops below. Can someone explain to me in detail what each loop is doing and why is are the loops constructed in this way? public class Pyramid { public static void main(String[] args) { int size = 15; for (int i = 1; i <= size; i += 2) { for (int k = 0; k < (7 - i / 2); k++) { System.out.print(" "); } for (int j = 1; j <= i; j++) { System.out.print("*"); } System
