Hi!
I have seen that D offers basically similar constructs to Java
for example for creating multithreaded applications. I would
like to understand better what are the real advantages that D
offers. Does D offer something that other known programming
languages, such as C++, Java and Python, do not offer? An
exhaustive explanation with concrete examples would be nice.
Moreover, could you also explain why D was designed to
synchronize entire classes instead of single methods. If I
synchronize single methods (in Java for example), I could still
be able to use other non-synchronized methods without needing
to acquire the lock, so I don't understand this decision.
I don't know what was the decisive point of the decision but in
can't help but note that it makes a lot of sense because D has
functions.
Object methods are meant to be used with the encapsulated data.
If it doesn't touch those data then it must be a function, it has
nothing to do as a method. If it does touch those data then in
multithreaded applications synchronizing only one amongst others
doesn't make any sense: encapsulated data is a share resource. In
java you don't have functions, only methods, so I sort-of
understand why they did it that way. But in any other (sane?)
language functions should be decoupled from methods anyway.
