 Posted: Thu Feb 09, 2006 1:23 pm Post subject: Private Function |
 |
|
I just finnished converting a school assignment from Java to D. And I realized that I was calling a private function from the main function. So my question is why does.
| Code: | import std.stdio;
int main() {
TestClass test = new TestClass();
test.privateMethod();
return 0;
}
class TestClass {
private:
void privateMethod() {
writefln("You made it in!");
}
} |
Work?

because you put them in the same source file.
The private methods of TestClass can be called by any method defined in the same source file.
Put your class definition in a separate file called testme.d, and put "module testme;" at the top of it. Then, at the top of your main file, put "private import testme;" to include it. Now try to compile and you will get an error about the private method not being accessible. |

Thanks, it isn't imperative that I limit the access (the method was supposed to be public) I was just confused. Coming from Java private only that class can access.

In D, private means private to the module, not private to the class. And a module is the source file. This means that only things in the same source file can access private members.
