hierarchy

问题 I have a small class hierarchy that I'm having trouble implementing copyWithZone: for. I've read the NSCopying documentation, and I can't find the correct answer. Take two classes: Shape and Square . Square is defined as: @interface Square : Shape No surprise there. Each class has one property, Shape has a "sides" int, and Square has a "width" int. The copyWithZone: methods are seen below: Shape - (id)copyWithZone:(NSZone *)zone { Shape *s = [[Shape alloc] init]; s.sides = self.sides; return

问题 I have some data like this : (AT sql sERVER) MemberID,ParemtID,Amt,OtherInfo 1, NULL, 200,dfdsf 2, 1, 300,DFDF 3, 1, 400,DFS 4, 3, 75,NULL Now I want build Tree like this : Only using JS. Above data can be passed in JSON / XML / CSV / Formatted Text How can i generate such dynamic tree in JS only ? Please don't suggest PHP / .NET solutions. I would prefer a JQuery. 回答1: And, here you go: http://jsfiddle.net/vVmcC/ http://jsfiddle.net/vVmcC/4/ You'll want to style it up yourself, obviously.

问题 I would like to convert a nested xml to flatten xml using XSLT. Incoming xml Structure would be similar but the node names would change for the incoming xmls, so would like to handle in dynamically Sample input <?xml version="1.0" encoding="UTF-8"?> <queryResponse> <Account> <Id>0010</Id> <Name>AA</Name> <RecordTypeId>0122/RecordTypeId> <RecordType> <Id>012</Id> <DeveloperName>Legal_Associate</DeveloperName> </RecordType> </Account> <Account> <Id>0011</Id> <Name>BB</Name> <RecordTypeId>0123<

问题 Trying to do a classic hierarchy tree in SQL, using SAS (which does not support WITH RECURSIVE, so far as I know). Here's simplified data structure in existing table: |USER_ID|SUPERVISOR_ID| So, to build a hierarchy, you just recursively join it x number of times to get data you are looking for, where SUPERVISOR_ID = USER_ID . In my company, it is 16 levels. This issue comes when trying to get a branch to terminate for each user. For example, let's consider User A at level 1 has Users B,C,D,

问题 I've created some sort of "dependencies" table that contain the entire dependencies of ours night process. The table looks like this: GRAND_MODEL | WAIT_4_MODEL_NAME test test1 test test2 test test3 test2 test3 test3 test4 test4 test5 This table means -> test needs to wait for test1 , test2 , test3 in order to finish, but also it needs to wait for test4 and test5 , because test3/4 waits for them . test1 doesn't wait for anything , test2 waits for test3 and therefore also for test4 and

问题 From time to time I find myself often writing a data structure of "parents" and "children", where: A parent has references to 0 to N distinct children. A child has a reference to 0 parents or 1 parent. The reference must be mutual. For any given parent, any child that it references must also reference the given parent back. For any given child, the parent that it references must reference the given child back. It's impossible to violate the above rules through use of members accessible from

问题 I would like to generate the 'hierarchy id' values which is denoted in red. The value is the lowest level of id in the hierarchy. The highest level of hierarchy is 'ALL Service Groups' and the lowest level is 'LL800_GB05'. They are related with Parent ID and ID. The attached image is only a sample set. Update-- I have formed a relationship and lineage. Now i know the highest member of Hierarchy.I want to associate the lowest childID for each row in a new column. I tired doing an inner join on

问题 In GWT if I do RootPanel.get("someDiv").add(myPanel); I invariably get: <div id="someDiv"><div></div></div> But, I just want 1 level of hierarchy, i.e., <div id="someDiv"><div> where the someDiv contains myPanel. Any ideas? Thanks! 回答1: A Panel has to be a div (or table or span). Your RootPanel is a div, and the Panel you add to it is a div. If you're writing a full-page app, RootPanel.get() returns the element, so adding a div to that will only result in one div inside the But honestly,

问题 I have a set of data that models a hierarchy of categories. A root category contains a set of top-level categories. Each top-level category contains a set of sub-categories. Each sub category has a set of organizations. A given organization can appear in multiple sub categories. The leaf nodes of this hierarchy are organizations. An organization can potentially appear in multiple sub-categories. The data is stored in three SQL tables: organizations organization_id organization_name 1 Org A 2

问题 When I push the twitter image in the game, I want to show share image(SLComposeViewController's modal display). But, when I push the twitter button, the display doesn't show and the log says like the title. Then, I searched similar issues but I am not sure what should I do... [ViewDidLoad] and [ViewDidAppear] is important thing, I know. Below is my code. ViewController.m #import "ViewController.h" #import "NewGameScene.h" #import <Social/Social.h> #import "GameOverScene.h" @interface
