Hi Guys,
I came accross a couple of questions while reading the
NeXT Concept document. I would appreciate if any one can
give me some help. My questions are listed in the following:
1] Can a client of a NeXT Step window server be running
on a remote host? If this is possible, under which
document is this capability documented?
2] Does NeXT Step take advantage of MACH's threading,
virtual memory management and messaging facilities?
Is there any documentation on how application programs
can benefit from the MACH facilities?
3] In Concepts, there is an example, illustrating the use
of SUPER in Objective-C, in the following way:
In B.h:
class B: A {
.
.
}
In B.m:
+ new
{
B *bInstance;
bInstance = [super new];
.
.
return bInstance;
}
The semantics illustrated above seems to imply that
bInstance will be pointing an instance of A since
"super" causes the invokataion of A's new.
Will class object B return a structure, which properly
represents the newly created instance of B, if B has
additional instance variables other than A's?
Thanks in advance for your help.
