Pointer-less targets
====================
There are some bytecodes/VMs that do not support interior pointers, i.e.
a pointer that points to a field inside a struct or an array element inside
an array. JVM is one such example.
However, that can be solved by creating "proxy types" for having
mutable references to primitive types:
// Interface
public interface MutableIntReference {
public void set(int value);
public int get();
}
// For structs:
class MyStruct {
public int a;
}
public class Ref_a implements MutableIntReference {
private final MyStruct target;
public Ref_a(final MyStruct target) {
this.target = target;
}
@Override
public void set(final int value) {
target.a = value;
}
@Override
public void get() {
return target.a;
}
}
// For arrays:
public class IntElementReference MutableIntReference {
private final int[] target;
private final int index;
public IntElementReference(final int[] target, final int index) {
this.target = target;
this.index = index;
}
@Override
public void set(final int value) {
target[index] = value;
}
@Override
public void get() {
return target[index];
}
}
