Hi I wonder how can I implement the STL map sorting by value. For example, I have a map m map<int, int>; m[1] = 10; m[2] = 5; m[4] = 6; m[6] = 1; and then.. I'd like to sort that with the m's value. So, if I print the map, I'd like to get the result like m[6] = 1 m[2] = 5 m[4] = 6 m[1] = 10 this. How can I sort like this way? Is...
Suppose that I have a multimap (which maps multiple values to a single key), and then I decide that I need to remove all but the first/last/predicate-matching value for all keys. After this operation, I have a traditional map (which maps a single value to a single key). Is there a word that describes this operation? The best I've come...
I want to implement some sort of lookup table in C++ that will act as a cache. It is meant to emulate a piece of hardware I'm simulating. The keys are non-integer, so I'm guessing a hash is in order. I have no intention of inventing the wheel so I intend to use std::map for this (though suggestions for alternatives are welcome). The q...
In code below: map<string,vector<int>> create(ifstream& in, const vector<string>& vec) { /*holds string and line numbers into which each string appears*/ typedef map<string,vector<int>> myMap; typedef vector<string>::const_iterator const_iter; myMap result; string tmp; unsigned int lineCounter = 0; while(st...
Okay, hope you can help med here :) I have been searching everywhere to figure this out, but haven't had any luck. I know about Annotations and how to overlay them on a map on the iPhone. But what if I have location like in the forest where there arent any roads or anything. What I am asking is, how can I overlay a custom image (map) ...
I have a question regarding map api. I was using the the google map api in my website before. But since I have encryption the site using HTTPS/SSL support, the google map api stopped working. I checked online, and realised that google has a Premier account only that would allow me to use HTTPS supported maps api and it cost $10,000 per...
Hi, I have read the doc and some tutorials to get a .kml file working launching the google maps activity. When I hosted the file in a server, this works perfectly: Intent myIntent = new Intent( android.content.Intent.ACTION_VIEW, Uri.parse("geo:0,0?q=http://somedomain.com/file.k...
Hi, I'm developing an application on GlassFish v3 which uses Suns-RI of JavaEE6 and JSF2.0, etc. And the bad thing is, that no changes/switches away from Suns RI can be made (to use MyFaces or something like that). Now, the problem is, that I want to build HtmlDatatable by hand ( in Java code). The datatable should represent a jav...
Can any one please guide me to look in depth about the Data Structures used and how is it implemented in the List, Set and Maps of Util Collection page. In Interviews most of the questions will be on the Algorithms, but I never saw anywhere the implementation details, Can any one please share the information. ...
I have a rather simple hadoop question which I'll try to present with an example say you have a list of strings and a large file and you want each mapper to process a piece of the file and one of the strings in a grep like program. how are you supposed to do that? I am under the impression that the number of mappers is a result of the ...

I'm having trouble getting the setMap(null); function that everyone seems to be recommending to work. I believe it may be a problem with the way I've implemented the markers. If someone could take a look and let me know if you see something wrong I'd greatly appreciate it. LINK: http://www.dougglover.com/samples/UOITMap/v2/ ...
I have seen the examples presented here of how to draw a line but the examples only show how to do it with the mouse, by clicking. What I want to do is draw the line manually using JavaScript given a list of Longitude and Latitude coordinates. The reason I cannot work on the source provided in the link above is because they are only ca...
Is there a way to cache map data for offline use? we're creating a guide app that will be used in areas where there is no reception and will need to display maps in this environment is this possible? Cheers w:// ...
Hi, I have a small library of a few shortest path search algorithms. They were developed for simple undirected graphs (the normal representation - vertices and edges). Now I'd like to somehow apply them on a bit different scenario - where the maps are represented as 2-dimensional shapes, connected by shared edges (edges of the polygons,...

Hi, I just want to add some kind of markers which are listed beside map, then user can drag them in to map. I tried to use GEvent.addDomListener(domObj, "drag",functName); but it didn't works. Is there any way to do that? Thanks Dau ...
I would like to copy the content of one std::map into another. Can I use std::copy for that? Obviously, the following code won't work: int main() { typedef std::map<int,double> Map; Map m1; m1[3] = 0.3; m1[5] = 0.5; Map m2; m2[1] = 0.1; std::copy(m1.begin(), m1.end(), m2.begin()); return 0; } This won't work because co...
I tried to pass const with vector it works: Ex: void damn(const vector <bool> &bb) { for (int i=0; i<bb.size(); i++) cout<<bb[i]<<endl; } But when trying with map, it does not: void pas(const map <string, float> &mm) { cout<<mm["a"]; cout<<mm["b"]; } I wonder why it doesn't. ...
