Provides easy interoperability with Java code through JNI.
|
|
|
|
Given this Java:
|
|
```java
|
|
class Hello {
|
|
public native void hi(String s);
|
|
public native String stringFromJNI();
|
|
public native String returnNull();
|
|
public native void throwException();
|
|
static {
|
|
System.loadLibrary("myjni");
|
|
}
|
|
public static void main(String[] args) {
|
|
System.out.println("Hello from Java!");
|
|
Hello h = new Hello();
|
|
// we can pass data back and forth normally
|
|
h.hi("jni");
|
|
System.out.println(h.stringFromJNI());
|
|
System.out.println(h.returnNull()); // it can handle null too
|
|
// and even forward exceptions (sort of, it puts it in a RuntimeException right now)
|
|
h.throwException();
|
|
}
|
|
}
|
|
```
|
|
|
|
And this D:
|
|
---
|
|
import arsd.jni;
|
|
|
|
// if it was in a Java package, you'd pass that
|
|
// in the string here instead of "".
|
|
final class Hello : JavaClass!("", Hello) {
|
|
|
|
@Export string stringFromJNI() {
|
|
return "hey, D returned this";
|
|
}
|
|
|
|
@Export string returnNull() {
|
|
return null;
|
|
}
|
|
|
|
@Export void throwException() {
|
|
throw new Exception("exception from D");
|
|
}
|
|
|
|
@Export void hi(string name) {
|
|
import std.stdio;
|
|
writefln("hello from D, %s", name);
|
|
}
|
|
}
|
|

Exact details subject to change, especially of how I pass the exceptions over.

|
It is also possible to call Java methods and create Java objects from D with the `@Import` uda.
|
|
|
|
|
|
While you can write pretty ordinary looking D code, there's some things to keep in mind for safety and efficiency.
|
|
|
|
$(WARNING
|
|
ALL references passed to you through Java, including
|
|
arrays, objects, and even the `this` pointer, MUST NOT
|
|
be stored outside the lifetime of the immediate function
|
|
they were passed to!
|
|
|
|
You may be able to get the D compiler to help you with
|
|
this with the scope attribute, but regardless, don't
|
|
do it.
|
|
)
|
|
|
|
It is YOUR responsibility to make sure parameter and return types
|
|
match between D and Java. The library will `static assert` given
|
|
unrepresentable types, but it cannot see what Java actually expects.
|
|
Getting this wrong can lead to memory corruption and crashes.
|
|
|
|
$(TIP
|
|
When possible, use `wstring` instead of `string` when
|
|
working with Java APIs. `wstring` matches the format
|
|
of Java's `String` so it avoids a conversion step.
|
|
)
|
|
|
|
All [JavaClass] sub-objects should be marked `final` on the D
|
|
side. Java may subclass them, but D can't (at least not now).
|
|
|
|
Do not use default arguments on the exported methods. No promise
|
|
the wrapper will do what you want when called from Java.
|
|
|
|
You may choose to only import JavaClass from here to minimize the
|
|
namespace pollution.
|
|
|
|
Constructing Java objects works and it will pin it. Just remember
|
|
that `this` inside a method is still subject to escaping restrictions!

|
|
|
|
// FIXME: what about the parent class of the java object? Best we can probably do is an interface but perhaps it could be auto-generated by the JavaClass magic. It could take the list and just copy the @Import items.

|
|
lol if i wanted to try defining a new class in D, i'd prolly have to ctfe generate bytecode trampoline
|
|
to make a Java method that forwards to the native call. the actual method names would then need a magical
|
|
prefix or something to avoid namespace conflicts between the Java and the D.
|
|
I don't think I'll actually do it. But I legit think that is possible.
|
|
|
|
Perhaps could be like final class AllNew : JavaClass("package", AllNew, true) {
|
|
@Virtual void foo() {} // defines it here, but Java can override
|
|
@Override void bar() {} // overrides existing thing with new impl
|
|
}
|
|
and then @Import and @Export continues to work the same way.

If `main` is in Java, this is not necessary and should not be

used.

If you use this, you will need to link in a jni shared lib.

You can then mark your methods @Import if they are implemented in Java and you want

to call them from D, or @Export if they are implemented in D and want to be called

as a `native` method from Java.

Methods marked without either of these signifiers are not associated with Java.

You should not expect any instance data on these to survive function calls, since

associating it back with Java across calls may be impossible.
