should objects in array be automatically constructed during
array initialization?
Members of static arrays are initialized to their default values.
Example.
class ClassPoint {
int x,y;
}
This is initialized to null.
struct StructPoint {
int x,y;
}
This is initialized to StructPoint(0,0).
ClassPoint[8] arr; //static array of null references;
StructPoint[8] arr2;
arr[0].x=1 //error, there is no object
arr2[0].x=1 //OK.
Here I have two questions:
1) Can you have automatically constructed objects with default
class constructor?
No. It is possible to create a wrapper struct type with "alias
this" to ClassPoint[8], which defaults to preallocated objects,
but as a drawback each instance of such type would default to
same class references and this makes the hack mostly unusable.
2) Can you setup memory attributes for static array using
core.memory functions, say, to force GC not to scan this
portion of memory during collection?
I do not understand what you mean here.
