After watching Adam's most excellent presentation at Dconf, I'm
sure the book will be great! My copy gets here on Friday.
A question(s) regarding Chapter 5: Making a reference-counted
object:
(btw do we need separate thread for content-related questions?)
- point 5 (of How to do it...) says: "... and free the object if
necessary", but then in code:
~this() {
if(data is null) return;
data.refcount--;
writeln("Released. Refcount = ", data.refcount);
if(data.refcount == 0)
writeln("Destroyed.");
}
is actual freeing missing? Or am I missing something?
Later in same chapter: "... or being collected by the garbage
collector—its destructor is called, if present."
Is that really true? My understanding (and unfortunate test) is
that it is never guaranteed that d-tor of GD allocated object is
ever called. If that is the case then: is that true that dynamic
array of RefCountedObject does not guarantee any of d-tors
called? That would also mean that if any of objects in object
graph is GC-allocated then NONE of its child nodes have any
guarantees about destruction?
