template <typename First = ::fidl::VectorView<::fuchsia_ui_views::wire::ViewRef>, typename... Args, std::enable_if_t<!std::is_same_v<cpp20::remove_cvref_t<First>, fidl::ObjectView<::fidl::VectorView<::fuchsia_ui_views::wire::ViewRef>>>, int> = 0>::fidl::WireTableBuilder< ::fuchsia_ui_focus::wire::FocusChain> & focus_chain (First && first, Args &&... args_)The `focus_chain` is reported in order of dominance in the View
hierarchy; each adjacent pair of elements represents a
parent-child relationship.
The `focus_chain` MAY be unset when `FocusChain` message is received, if
the message is sent very early in the scene setup, before the first
view is available.
When `focus_chain` is set, however, the root View is always present
and occupies slot 0 in the `focus_chain`. The newly-focused View
receives a `fuchsia.ui.input.FocusEvent` and occupies the final slot
in the vector.
If a View gets destroyed, a `FocusChain` holder that listens will
receive a `ZX_EVENTPAIR_PEER_CLOSED` signal on the corresponding
`ViewRef`.
## Invalidation.
A FocusChain is invalid if any one if its ViewRefs is
invalid.
