I have a map in my application that shows locations from Gowalla. I use an ItemizedOverlay with a simple default marker, but as the items are drawn, I swap the default marker out with the location's icon downloaded 9and cached on disk) from Gowalla. The problem is that if there are a lot of locations on screen (say 30), the size of the...

This might seem a simple question but I've been trying for a couple of hours now (without having to implement hashCode comparison) to make containsKey working. To simplify things I'll post a simple code example that i'm having issues with: public class myPair { private int a; private int b; myPair(int x, int y) { a=x; b=y; } ...
I have a group of Events that occurred at some Dates. Each event has a Date field. Now I'd like to create a Map where for each Date (taken from all dates of events) I will assign List of Events that occurred on that date. So in pseudocode : public Map<Date, List<Event>> function(List<Event> list){ Date[]dates = new Date(list.len())...
Is there any common function (in apache commons or similar) to make maps from query-parameter-like strings? To specific: Variant a (Querystring) s="a=1&b=3" => Utils.mapFunction(s, '&', '=') => (Hash)Map { a:1; b:3 } Variant b (Cachecontrol-Header) s="max-age=3600;must-revalidate" => Utils.mapFunction(s, ';', '=') => (Hash)M...
Hello everyone. I'm making an app on android, using webview to load google map (using this url for my webview: http://gmaps-samples.googlecode.com/svn/trunk/articles-android-webmap/simple-android-map.html). but i can't put a marker on that webview, can't somebody tell me how? thanks very much (and sorry because my terrible English :)) ...
I need a memory-efficient data structure for for storing about a million key--value pairs, where keys are strings of about 80 bytes, and values are strings of about 200 bytes, the total key and value size being about 280MB. I also need efficient lookup of value by key, preferably a hash-map. The memory overhead should be as little as pos...
I have an STL map that I want to iterate through, and can't seem to get the code to work.

I need to create a map that can contain as its value any basic data type such as double,float,string, char etc... to store values from a request for a server component. I was thinking of using a map such as this: std::map<std::string, void*>, however I don't know that this is a very good solution. I wondered if anyone can advice on a b...

Is it a good idea to do the following in C++: typedef std::map<std::string, boost::any> MyVals; // Is the following typedef'd type inside a map a good idea? typedef std::map<std::string, MyVals> TagValues; These maps will be used a lot for sequential insertion and removal. ...
Hi! I'm having difficulties implementing a generic 'map' function over arrays. I started with the following draft: void MapArray(void * src, void * dest, void * (f)(void *), size_t n, size_t elem) { unsigned int i = 0, j = 0; void * temp = malloc(elem); for(i = 0; i<n, i++) { temp = (f)((char *) src) + i)); for...

I'm working my way through the O'Reilly jQuery Cookbook. On p.65 there is an example that looks wrong to me, but I'm new to jQuery (less than a week) so I figure it is very likely that I am the one who is confused. The code intends to get the first three items from an ordered list & do something with them; for simplicity's sake (on the ...

Basically I want to use a static map created by me, so I think google map API s may not be used in this case. My development platform is unix. Can you please suggest...
