The Kotlin DSL replaces such dynamic resolution with type-safe model accessors that work with model elements contributed by plugins.

[[kotdsl:accessor_applicability]]
=== Understanding when type-safe model accessors are available

The Kotlin DSL currently provides various sets of type-safe model accessors, each tailored to different scopes.

    System.arraycopy(array, 0, dst, dstOff, size);
    return dstOff + size;
  }

  // The fake cast to E is safe because the creation methods only allow E's
  @Override
  @SuppressWarnings("unchecked")
  public E get(int index) {
    checkElementIndex(index, size);
    // requireNonNull is safe because we guarantee that the first `size` elements are non-null.
    return (E) requireNonNull(array[index]);
  }

  @Override
  int indexOf(@CheckForNull Object target) {
    if (!contains(target)) {
      return -1;
    }
    // The cast is safe because of the contains check—at least for any reasonable Comparable class.
    @SuppressWarnings("unchecked")
    // requireNonNull is safe because of the contains check.
    C c = (C) requireNonNull(target);
    return (int) domain.distance(first(), c);
  }
