 /**
  * <h3>Passing Arguments</h3>
- * 
+ *
  * <p>
- * A guest language can pass its own custom arguments when invoking a Truffle method by creating a
- * subclass of {@link Arguments}. When invoking a call target with
- * {@link CallTarget#call(Arguments)}, the arguments can be passed. A Truffle node can access the
- * arguments passed into the Truffle method by using {@link VirtualFrame#getArguments}.
+ * When invoking a call target with {@link CallTarget#call(Object[])}, arguments can be passed. A
+ * Truffle node can access the arguments passed into the Truffle method by using
+ * {@link VirtualFrame#getArguments}.
  * </p>
- * 
+ *
  * <p>
  * The arguments class should only contain fields that are declared as final. This allows the
  * Truffle runtime to improve optimizations around guest language method calls. Also, the arguments
- * object must never be stored into a field. It should be created immediately before invoking
- * {@link CallTarget#call(Arguments)} and no longer be accessed afterwards.
+ * object array must never be stored into a field. It should be created immediately before invoking
+ * {@link CallTarget#call(Object[])} and no longer be accessed afterwards.
  * </p>
- * 
+ *
  * <p>
  * The next part of the Truffle API introduction is at {@link com.oracle.truffle.api.test.FrameTest}
