EE::Map inside of a struct
How do you use EE::Map inside of a struct? For instance, if you take the Map tutorial and just wrap the map variable inside of a struct, the map can no longer find the Create or Compare functions. Not sure why and I can't find an explanation on this site or Google.

Code:
struct Test
{
    Map<Key,Data> map(Create,Compare,NULL);
};

Produces these errors:

Code:
error C2061: syntax error : identifier 'Create'
Error: function 'Create' is not a type name

RE: EE::Map inside of a struct
Well it can work if you init the map in the constructor if thats what u mean:


PHP Code:
struct Test
{
static 
Bool Create(Object &objint &keyPtr user)
    {
        return 
true;
    }

    static 
Int Compare(int &aint &b)
    {
        if(
a<b)return -1;
        if(
a>b)return +1;
        return  
0;
    }

 
Map<Key,Datamap(Create,Compare,NULL);
}


Test::Test() : map(Test::Create,Test::Compare,NULL)
{

Unfortunately, this does not work for me. Gives the same two errors as above (these errors also apply to Compare as well, obviously) and these:

Code:
EE::Map<Key, Data> Test::map(<error-type>, <error-type>, <error-type>)
Error: "map" is not a nonstatic data member or base class of class "Test"

Still unable to find Create and Compare functions.

RE: EE::Map inside of a struct
did you add static to the create/compare functions?

They always were static.

Yes but u need to set: Map<int, TestObj> map; in the header file and the Test::Test() : map(Test::Create,Test::Compare,NULL) in the cpp file...

This should work tho...

Eureka! That did the trick.

Code:
struct Test
{
    // Create and Compare functions...

    Map<Key,Data> map; // (Create,Compare,NULL); <== leave off
    Test();
};

Test::Test() : map(Test::Create,Test::Compare,NULL) {}

Thanks!
