public final class IntByReference extends AbstractNumberReference<Integer>
For example, the following C code,
extern void get_a(int * ap); int foo(void) { int a; // pass a reference to 'a' so get_a() can fill it out get_a(&a); return a; }
Would be declared in java as
interface Lib { void get_a(@Out IntByReference ap); }
and used like this
IntByReference ap = new IntByReference(); lib.get_a(ap); System.out.printf("a from lib=%d\n", a.intValue());
