There are only 2 possible situations: - * either the newly created proxy is the child of a proxy, - * or it is the sibling of a proxy created on the fly. - * In both cases, the parent is a proxy with children. - * Such nodes are called child proxies. - * How to compute the offset of a proxy ? - * The offset of root proxy objects is exactly - * the offset of the ref they replace. - * The offset of other proxies is their owner's, - * except when pointing to a root proxy. - * What happens for cascading forms ? - * Here is an example diagram - * - * At parse time, the arrow means "owns": - * sheet0 -> ref_to1 - * - * target1 -> ref_to2 - * - * target2 -> child22 - * - * After replacing the refs: - * sheet0 -> proxy00 -> proxy01 -> proxy02 - * | | | - * target1 -> proxy11 -> proxy12 - * | | - * target2 -> proxy22 - * - * proxy00, proxy11 and proxy22 are root proxies. - * Their offset is the one of the ref they replace - * proxy01, proxy02 and proxy12 are child proxies. - * Their proxy is the one of their parent. - * Optimization. - * After all the refs are replaced, there are only root nodes - * targeting standard node. We make sure that each child proxy - * also targets a standard node. - * It is possible for a proxy to have a standard sibling - * whereas its target has no sibling at all.
