hierarchy

I am having real trouble tracking down a bug and it would help be a lot to know which method called a certain method. Is there an easy way to get a call hierarchy from java? Java is a small part of the app so I cannot compile and run the whole app in eclipse/net beans so I don't have access to an IDE debugger's call hierarchy. Thread.currentThread().getStackTrace(); or Exception ex = new Exception(); ex.printStackTrace(); It's fairly slow, but fine for debugging purposes. API docs here . Java is a small part of the app so I cannot compile and run the whole app in eclipse/net beans so I don't

I am trying to implement hierarchyID in a table (dbo.[Message]) containing roughly 50,000 rows (will grow substantially in the future). However it takes 30-40 seconds to retrieve about 25 results. The root node is a filler in order to provide uniqueness, therefor every subsequent row is a child of that dummy row. I need to be able to traverse the table depth-first and have made the hierarchyID column (dbo.[Message].MessageID) the clustering primary key, have also added a computed smallint (dbo.[Message].Hierarchy) which stores the level of the node. Usage: A .Net application passes through a

I am trying to figure out how type hierarchies work in Agda. Assuming I define a set type X: X : Set and then proceed to constructing an inductive type data Y : X -> Set where What is the type of X -> Set ? Is it Set or Type? Thank you! Well, why not ask Agda itself? I'm going to use excellent Agda mode for Emacs. We start with: module Hierarchy where postulate X : Set data Y : X → Set where -- empty We have to load the file using C-c C-l ; this typechecks the file, turns ? s into holes, does syntax highlighting and so on. Now, there is a command "Infer (deduce) type" available via C-c C-d ,

I'm trying to do a chart based on http://mbostock.github.com/d3/talk/20111116/bar-hierarchy.html , the only difference being that I'd like to use a log scale for the x-axis. Here's my fiddle: http://jsfiddle.net/JhDVC/5/ As you can see, the x-axis is defined at line 4: x = d3.scale.linear().range([0, w]), If I change it for x = d3.scale.log().range([0, w]), Then it doesn't work (nothing is rendered), throwing these error messages: Error: Invalid value for <rect> attribute width="NaN" Changing the domain setting from x.domain([0, root.value]).nice(); to x.domain([1, root.value]).nice(); shows

I have a table having hierarchical menus like "id" "parent_id" "name" 1 0 menu 2 1 item1 3 2 item1_1 4 1 item2 5 4 item2_1 ... ... and I have 100s of menu items here. In order to get all items in an array I have to write a recursive function like this getmenu function(parent_id = 1) { $items = mysql_query("SELECT id FROM table WHERE parent_id = " + parent_id); while ($item = msyql_Fetch_assoc($items)) { ...here I put them in array and call recursive function again to get sub items... getmenu($item['id']); } } but this executes 100s of queries. Is this the best way to do this, to get

If I have a Class like below. How do i traverse through it until its property SomeObjects.count = 0 public class SomeObject { public String Name { get; set; } public List<SomeObject> SomeObjects { get; set; } } Many Thanks Here is a generic example of how you can traverse a composite object: public static class TraversalHelper{ public static void TraverseAndExecute<T>(this T composite, Func<T,IEnumerable<T>> selectChildren, Action<T> action) where T: class { action.Invoke(composite); composite.TraverseAndExecute(selectChildren, action, new List<T>{ composite }); } private static void
