Hi, In a controller, I have populated a map that has a string as key and a list as value; in the gsp, I try to show them like this:
<g:each in="${sector}" var="entry" >
<br/>${entry.key}<br/>
<g:each in="${entry.value}" var="item" >
${item.name}<br/>
</g:each>
</g:each>
The problem is that item is considered as string, so I ...
I want to create a Map object that can lose value only if we explicitly delete it from map.
I have created Map object like
public static Map<Long,String> listUser =new HasMap<Long,String>();
but every time class object is created new instance of Map is also created that contain null value. I want to create a Map instance that contain ...
I want to insert n elements into a map where n is known ahead of time. I do not want memory allocation at each insertion. I want all memory allocation at the beginning. Is there a way to do this? If so, how? Will writing some sort of memory allocator help?
I ran GMan's code and got the following output. GetMem is printed from a call to ...
I'd like to use iterators from an STL list as keys in a map. For example:
using namespace std;
list<int> l;
map<list<int>::const_iterator, int> t;
int main(int argv, char * argc) {
l.push_back(1);
t[l.begin()] = 5;
}
However, list iterators do not have a comparison operator defined (in contrast to random acc...
Hi,
I'm not familiar yet with WebOS dev (just started this weekend) but I didn't find any "MapView" widget in the reference library.
Is there any way to include a WebView in my app or do I have to start the map app from my app ?
Thanx.

Hi,
I only know that the difference between hashmap and map is that hashmap is implemented with hash function but map is implemented with tree. Could any body add anything more?
Based on this, is there any thing hashmap can do but map cannot?

We are loading a large flat file into BizTalk Server 2006 (Original release, not R2) - about 125 MB. We run a map against it and then take each row and make a call out to a stored procedure.
We receive the OutOfMemoryException during orchestration processing, the Windows Service restarts, uses full 2 GB memory, and crashes again.

I need to use a different datasource inside a map in Android than the google provided data. Is there a way to change the datasource to a tile based service (openstreetmap.org for example)?
Or are there other Android map APIs which are OpenSource and can be adapted (except Ericcson Mobile Maps - this doesn't work for me because of the li...
Is there a version of either java.beans.PropertyChangeSupport or com.jgoodies.binding.beans.ExtendedPropertyChangeSupport which is helpful for supporting change listeners along the lines of a Map or EnumMap? (a key-value store with known limited keys and change listeners for all the values in the map)
I don't really need beans-type acce...
Hi,
I have a class:

and a mapping file:
<class name="User" table="Users">

I want to have something similar to map but while iterating I want them to be in the same order as it is added.
Example
map.insert("one", 1);
map.insert("two", 2);
map.insert("three", 3);
While iterating I want the items to be like "one", ""two", "three"..By default, map doesn't provide this added order. How to get the map elements t...
Hello,
I am writing an Apache module in C++. I need to store the common data that all childs need to read as a portion of shared memory. Structure is kind of map of vectors, so I want to use STL map and vectors for it. I have written a shared allocator and a shared manager for the purpose, they work fine for vectors but not for maps, bel...
I'm creating an app with AppEngine (Java) that needs access to local map information.
In general, I'd like to search any query such as: gas stations, cheap restaurants, banks, or whatever in a certain area.
What is the best way to do this, and with which Service or API ?

Using jQuery's position() or offset(), I can't seeme to get the top/left coordinates of an image map area. It works in FF, but nothing else - no webkit, IE, Opera.
$('area').bind("click",function(){
alert($(this).position().left);
});
<area shape="rect" coords="14,25,205,150" href="#">
Anyone know of a different way to access these...
In the following example a std::map structure is filled with 26 values from A - Z (for key) and 0 - 26 for value. The time taken (on my system) to lookup the last entry (10000000 times) is roughly 250 ms for the vector, and 125 ms for the map. (I compiled using release mode, with O3 option turned on for g++ 4.4)
But if for some odd reas...
Hello,
I have a constructor that looks like this (in c++):
Interpreter::Interpreter() {
tempDat == new DataObject();
tempDat->clear();
}
the constructor of dataObject does absolutely nothing, and clear does this:
bool DataObject::clear() {
//clear the object
if (current_max_id > 0) {

In the interpreter for my experimental programming language I have a symbol table. Each symbol consists of a name and a value (the value can be e.g.: of type string, int, function, etc.).
At first I represented the table with a vector and iterated through the symbols checking if the given symbol name fitted.
Then I though using a map,...

I need to see the contents of a std::map variable while debugging. However, if i click on it in the Autos/Locals Tab, I see implementation specific stuff, instead of the keys and its contents which I want to look at. Is there a work-around i'm missing ?
