> Use an {{@NotNull}} or {{@RequiresNonNull}} annotation on a method to generate a {{null}} check and throw, by default, an {{IllegalArgumentException}} if null. Also clean the stack trace.
> {code:java|title=Example Interface}
> @Message(id = 123, value = "Name cannot be null")
> @NotNull(IllegalArgumentException.class)
> void requireNotNull(String name);
> {code}
> {code:java|title=Example Generated Code}
> @Override
> public void requireNotNull(final String name) {
>     if (name == null) {
>         final IllegalArgumentException result = new IllegalArgumentException(String.format(invalidUser$str(), name));
>         final StackTraceElement[] st = result.getStackTrace();
>         result.setStackTrace(Arrays.copyOfRange(st, 1, st.length));
>     }
> }
> {code}
> The {{@Param}} annotation could be used along with {{@Pos}} for formatting possibly.
