public final class ByteByReference extends AbstractNumberReference<Byte>
For example, the following C code,
extern void get_a(char *ap); int foo(void) { char 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 ByteByReference ap); }
and used like this
ByteByReference ap = new ByteByReference(); lib.get_a(ap); System.out.printf("a from lib=%d\n", a.byteValue());
