BridJ problems with enums #414
Description
It may be just my ignorance so apologies in advance if that's the case, but would still appreciate someone pointing me in the right direction!
I'm having problems with the BridJ output from JNAerator for enums.
// === C HEader File ===
typedef enum
{
None = 0,
Apple = 1,
Pear = 2,
Orange = 4,
Banana = 8
} Fruit;
void getFruit(Fruit* fruit);
// ===================
// JNAerate the above header with
JNAERATOR="/Tools/JNAerator/jnaerator-0.12-SNAPSHOT-20130323-2.jar"
java -jar $JNAERATOR -runtime BridJ -jar FruitSalad.jar -direct -library fruitsalad -mode StandaloneJar Headers/*.h
// Now I find the following problems when I attempt to use the jnaerated java classes (demonstrated in this test app)
import junit.framework.Assert;
import org.bridj.IntValuedEnum;
import org.bridj.Pointer;
import org.junit.Test;
import fruitsalad.FruitsaladLibrary;
import fruitsalad.FruitsaladLibrary.Fruit;
public class TestFruitSalad {
@Test
public final void testEnumAllocation() {
/*
* Java compile fails on the following with:
*
* The method getFruit(Pointer<IntValuedEnum<FruitsaladLibrary.Fruit>>) in the type

*/
Pointer<Fruit> pFruit = Pointer.allocate(Fruit.class);
FruitsaladLibrary.getFruit(pFruit);
}
@Test
public final void testEnumPointerTo1() {
/*

*/
Fruit fruit = Fruit.Apple;
Pointer<Fruit> pFruit = Pointer.pointerTo(fruit);
FruitsaladLibrary.getFruit(pFruit);
}
@Test
public final void testEnumPointerTo2() {
/*

Fruit fruit = Fruit.Apple;
Pointer<IntValuedEnum<Fruit>> pFruit = Pointer.pointerTo(fruit);

System.out.printf("fruit.value()= %d\n", fruit.value()); // OK
System.out.printf("fruit=%s\n", fruit.toString()); // FAILS
Assert.assertTrue("fruit2.value == Fruit.Banana.value", Fruit.Banana.value == fruit.value()); // SUCCEEDS
Assert.assertTrue("fruit2.equals(Fruit.Banana)", Fruit.Banana == fruit); // FAILS
}
