map

问题 I am using JQVmap (https://github.com/manifestinteractive/jqvmap) to output a map on a site. Instead of doing something when you hover each country, I want them to be grouped into regions. For example, instead of Canada, US & Mexico, I would like all three to show the hover state when you hover over any of them and make a grouping of countries. I have seen multiple posts on how to color sets of countries, but each country still has its own hover state then and doesn't trigger the hover state

问题 [ Preface: The associative C++ containers like std::map are a bit like micro-databases with just one key column. Boost's bimap elevates this to a two-column table with lookup in both columns, but that that's as far as the analogy goes -- there's no "polymap" that generalizes the idea.] In any event, I want to keep thinking of maps as databases, and I now wonder if there is an iterator (or some other solution) that allows me to do a UNION of several constituent maps. That is, all maps have the

问题 I have a map such as m=[ "james":"silly boy", "janny":"Crazy girl", "jimmy":"funny man", "georges":"massive fella" ]; I want to sort this map by its value but ignoring the case (this is really why the custom sort is needed). Hence I figured I had to implement a custom sort using a closure. But I'm brand new at Groovy and been struggling to get this very simple task done! The desired results would be: ["janny":"Crazy girl", "jimmy":"funny man", "georges":"massive fella", "james":"silly boy"]

问题 Ever since Joshua Katz published these dialect maps that you can find all over the web using harvard's dialect survey, I have been trying to copy and generalize his methods.. but much of this is over my head. josh disclosed some of his methods in this poster, but (as far as I know) has not disclosed any of his code. My goal is to generalize these methods so it's easy for users of any of the major United States government survey data sets to plop their weighted data into a function and get a

问题 I am not to Clojure and attempting to figure out how to do this. I want to create a new hash-map that for a subset of the keys in the hash-map applies a function to the elements. What is the best way to do this? (let [my-map {:hello "World" :try "This" :foo "bar"}] (println (doToMap my-map [:hello :foo] (fn [k] (.toUpperCase k))) This should then result a map with something like {:hello "WORLD" :try "This" :foo "BAR"} 回答1: (defn do-to-map [amap keyseq f] (reduce #(assoc %1 %2 (f (%1 %2)))

问题 I am trying to define a Map literal with key: String , value: (Any)=>String . I tried the following, but get a syntax error: def foo(x: Int): String = /... def bar(x: Boolean): String = /... val m = Map[String, (Any) => String]("hello" -> foo, "goodbye" -> bar) 回答1: Funny that no one actually gave a type that would work. Here's one such: def foo(x: Int): String = x.toString def bar(x: Boolean): String = x.toString val m = Map[String, (Nothing) => String]("hello" -> foo, "goodbye" -> bar) The

问题 I have two maps: Map<String, Object> map1; Map<String, Object> map2; I need to receive difference between these maps. Does exist may be apache utils how to receive this difference? For now seems need take entry set of each map and found diff1 = set1 - set2 and diff2 = set2- set1. After create summary map =diff1 + diff2 It looks very awkwardly. Does exist another way? Thanks. 回答1: How about google guava?: Maps.difference(map1,map2) 回答2: Here is a simple snippet you can use instead of massive

问题 I'm trying to figure out how to manually trigger events for Leaflet polygons (loaded via GeoJSON). In a nutshell, I have a Leaflet map with numerous polygons. I also have a regular hyperlink outside of the map that when clicked, should trigger a mouseover event (or any event really) on a particular polygon. How do I assign ID's to all of my polygons so that I can bind hyperlink(s) to a specific polygon's event? Or is that even the most logical way of doing this? Ultimately, I'm trying to
