Title: Working with getWeapons() from CargoAPI
Post by: Ghoti on September 17, 2012, 06:02:58 PM

I've being try to get the list of weapons in Cargo, the problem is that Janino doesn't play well with generics for some odd reason, and I can't define a proper return value for the list

Code

List<CargoItemQuantity<String>> container = cargo.getWeapons();

I have to define it like this

Code

List container = cargo.getWeapons();

The problem with that is now I've got a list of objects.

I can't cast like this

Code

(CargoItemQuantity<String>) container

presumably for the same reason above. Which is OK I guess cause I can do this....

Code

CargoItemQuantity ciq = (CargoItemQuantity) container.get(x);

but... and I don't know why. When I get to this long annoying rabbit hole and have to cast the String. I get this

Code

Caused by: org.codehaus.commons.compiler.CompileException: Array initializer not allowed for non-array type "java.lang.String"

grrrrr.... Does anyone have any working examples using this method?

Code

String s = (String) ((CargoItemQuantity) cargo.getWeapons().get(x)).getItem();

Wow, looking through my code I realized I have never used the getWeapons() method, so I can't help with that. Sorry.

However, you might have better luck looping through getStacksCopy() and filtering the stacks with isWeaponStack(). That would give you a List of CargoStackAPI objects, which pretty much obsolete CargoItemQuantity anyway. :)

Code

String s = (String) ((CargoItemQuantity) cargo.getWeapons().get(x)).getItem();

tjj that's just an inline version of the same code... The same code that gives me an error. I know you can inline it. I was just breaking it down.

I forgot about that isWeaponStack method. That will work. Thanks.

Also, again. Damn fine wizard, lazy.

Perhaps you should post the entire code segment in which you are encountering the problem, as in isolation janino has no trouble compiling the example I posted.

Either the problem is being caused elsewhere in your code, or it's a compiler bug due to the composition of code being compiled.

Ah so it does... With the use of comments and I narrowed the problem down to this:

Code

private static String makeWep[] = { ... };
private static String[] makeWep = { ... };

Apparently OK in Java 7, not in Java 5.

Damn it. Well this is embarrassing. Janino I would of liked a line number you know...

edit:
OK. I'm in business. Thanks guys.

Glad to be of help, even if it wasn't much. :)

I know you didn't say it, but Janino's restrictions (http://docs.codehaus.org/display/JANINO/Home#Home-limitations) are for the most part syntax only. Our scripts still have access to the entire Java 6 library that Starfarer uses.

Just making sure you don't artificially limit yourself. :)
