TArray& ListFiles( /* blah */ );
or this:
int ListFiles( TArray* /* blah */ );
Returning Templates
Author
Heya,
I''m having a serious problem here, I try to return a template class from a function and it all goes to hell. Basically I am trying to do this:
The problem is with your code; it''s not a compiler bug.
Try something like this:
Hope this helps.
Try something like this:
template TArray& ListFiles(/* blah */) {...}// Or...template int ListFiles(TArray *t, /* blah */);// Note: you may have to call your function like this:// TArray t = ListFiles(/* blah */); Hope this helps.
Sorry.... Let''s try this again, shall we?
template < typename T >
TArray< T >& ListFiles(/* blah */) {...}
// Or...
template < typename T >
int ListFiles(TArray< T > *t, /* blah */);
// Note: you may have to call your function like this:
// TArray< int > t = ListFiles< int >(/* blah */);
template < typename T >
TArray< T >& ListFiles(/* blah */) {...}
// Or...
template < typename T >
int ListFiles(TArray< T > *t, /* blah */);
// Note: you may have to call your function like this:
// TArray< int > t = ListFiles< int >(/* blah */);

Well the thing is that TArray, and BString are already defined classes, and that particular function is defined within another class.
i.e.
Strickly speaking
is just the return type.
And the way that I''m calling it is like so:
It still stuffs up then, so I am really wondering if its got anything to do with the = operator. Its just wierd...
i.e.
template class TArray { ... };// andclass BString { ... };// etc Strickly speaking
TArray& is just the return type.

TArray Stuff = Something.ListFiles(/* blah */); It still stuffs up then, so I am really wondering if its got anything to do with the = operator. Its just wierd...
It appears your templates got cut off (because this board seems to interpret angular brackets as HTML tags).
Anyway, you can''t do something like this:
TArray t = ...;
You have to give TArray a type. So it''d be like this:
You have to specify a type for the template class when you call it.
Also, if the return type is "TArray&" (and not "TArray< T >&"), and TArray is a template then that code is probably wrong. It needs to look like:
template< typename T >
TArray< T >& Something::ListFiles(/* blah */) { ... }

Yeah it got cut off, basically I have done everything that you have suggested it before, (I''m not that much of an idiot you know).
Oh well I''ll just make a wrapper class or something.
