How to use the inferno._HI function in inferno

function hydrateComponent(vNode: VNode, parentDOM: Element, dom: Element, context, isSVG: boolean, isClass: boolean, lifecycle: Function[]) {
  const type = vNode.type as Function;
  const ref = vNode.ref;
  const props = vNode.props || EMPTY_OBJ;
  let currentNode;

  if (isClass) {
    const instance = _CI(vNode, type, props, context, isSVG, lifecycle);
    const input = instance.$LI;

    currentNode = hydrateVNode(input, parentDOM, dom, instance.$CX, isSVG, lifecycle);
    _MCCC(ref, instance, lifecycle);
  } else {
    const input = _HI(renderFunctionalComponent(vNode, context, props));
    currentNode = hydrateVNode(input, parentDOM, dom, context, isSVG, lifecycle);
    vNode.children = input;
    _MFCC(vNode, lifecycle);
  }

  return currentNode;
}
