How to use the inferno-vnode-flags.VNodeFlags.ComponentFunction function in inferno-vnode-flags

let flags;
  let children;

  while (stack.length > 0) {
    _vNode = stack.pop();

    if (_vNode.dom === DOM) {
      return true;
    }

    flags = _vNode.flags;
    children = _vNode.children;

    if (flags & VNodeFlags.ComponentClass) {
      stack.push(children.$LI);
    } else if (flags & VNodeFlags.ComponentFunction) {
      stack.push(children);
    } else {
      flags = _vNode.childFlags;

      if (flags & ChildFlags.MultipleChildren) {
        let i = children.length;

        while (i--) {
          stack.push(children[i]);
        }
      } else if (flags & ChildFlags.HasVNodeChildren) {
        stack.push(children);
      }
    }
  }

function linkComponent({ location, match }): VNode {
    const isActive = !!(getIsActive ? getIsActive(match, location) : match);

    return createComponentVNode(
      VNodeFlags.ComponentFunction,
      Link,
      combineFrom(
        {
          'aria-current': isActive && ariaCurrent,
          className: isActive ? [className, activeClassName].filter(filter).join(' ') : className,
          onClick,
          style: isActive ? combineFrom(style, activeStyle) : style,
          to
        },
        rest
      )
    );
  }
