scala - Scala：插入异常及其管理

Answer 1

一旦我有一个名为NubLogger处理此类问题的类。不要问名字的选择...

public static void handle(Throwable t) {
    if (t == null) {  
        t = new Throwable(NubLogger.class.getName() + ".handle((Throwable)null)");            
    }
    if (t instanceof RuntimeException) {
        log(t);
        throw (RuntimeException) t;
    } else if (t instanceof Exception) {
        log(t);
        throw new RuntimeException(t);
    } else if (t instanceof Error) {
        log(t);
        throw (Error) t;
    } else if (t instanceof Throwable) {
        log(t);
        throw new RuntimeException(t);
    } else {
        t = new UnsupportedOperationException("Unknown throwable type: " + t.getClass(), t); 
        log(t);
        throw (RuntimeException)t;
    }
}

编辑

class Element (var name:String){

    // VALIDAZIONE DI ELEMENT
    // Preferrable variant - use val name, not var name
    require(name != null)

    // VALIDAZIONE DI ELEMENT 2
    // Will work with var-s
    def validate = name != null

}//class Element
