From class ViewHolder

`RowHeaderPresenter.ViewHolder!`	`getHeaderViewHolder()` Returns the view holder for the Row header for this Row.
`BaseOnItemViewClickedListener<Any!>!`	`getOnItemViewClickedListener()` Returns the listener for item click event.
`BaseOnItemViewSelectedListener<Any!>!`	`getOnItemViewSelectedListener()` Returns the listener for item or row selection.
`OnKeyListener!`	`getOnKeyListener()` Returns the key listener.
`Row!`	`getRow()` Returns the row bound to this ViewHolder. Returns null if the row is not an instance of `Row`.
`Any!`	`getRowObject()` Returns the Row object bound to this ViewHolder.
`Float`	`getSelectLevel()` Returns the current selection level of the Row.
`Boolean`	`isExpanded()` Returns whether the Row is in its expanded state.
`Boolean`	`isSelected()` Returns whether the Row is selected.
`Unit`	`setActivated(activated: Boolean)` Sets the row view's activated status. The status will be applied to children through `syncActivatedStatus(View)`. Application should only call this function when `RowPresenter#getSyncActivatePolicy()` is `RowPresenter#SYNC_ACTIVATED_CUSTOM`; otherwise the value will be overwritten when expanded or selected status changes.
`Unit`	`setOnItemViewClickedListener(listener: BaseOnItemViewClickedListener<Any!>!)` Sets the listener for item click event. RowPresenter does nothing but subclass of RowPresenter may fire item click event if it has the concept of item. OnItemViewClickedListener will override `View.OnClickListener` that item presenter sets during `Presenter#onCreateViewHolder(ViewGroup)`.
`Unit`	`setOnItemViewSelectedListener(listener: BaseOnItemViewSelectedListener<Any!>!)` Sets the listener for item or row selection. RowPresenter fires row selection event with null item. A subclass of RowPresenter e.g. `ListRowPresenter` may fire a selection event with selected item.
`Unit`	`setOnKeyListener(`
