Hmm... would be nice if there were a warning/error when __gshared 
is used without static in a class.

Using TreeSet and __gshared values

2014-09-03 Thread nrgyzer via Digitalmars-d-learn 

Hi guys,

I'm having some trouble using the treeset implementation of
Steven (dcollections) in conjunction with __gshared. When I do
the following:

class Entry
{
int value;
this(int v)
{
value = v;
}
int opCmp(Object o)
{
return -1;
}
}

void main()
{

auto tree = new TreeSet!Entry();
tree.add(new Entry(10));
tree.add(new Entry(20));
tree.add(new Entry(30));

foreach (ref entry; tree)
{
writeln(entry.value);
}
}

I'm getting the following output:

10
20
30

But when I replace the class as follows:

class Entry
{
__gshared int value;
this(int v)
{
value = v;
}
int opCmp(Object o)
{
return -1;
}
}

I'm getting the following output:

30
30
30

Do anyone have any ideas what can cause the problem?

i.e.

class Entry {
  __gshared int value;
  ...
  static int getValue () { return value; }
}

works ok.

you have only one 'value' variable for all your instances.
