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.
`Any!`	`getSelectedItem()` Return currently selected item inside a row ViewHolder.
`Presenter.ViewHolder!`	`getSelectedItemViewHolder()` Return `ViewHolder` of currently selected item inside a row ViewHolder.
`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(keyListener: OnKeyListener!)` Sets a key listener.
`Unit`	`syncActivatedStatus(view: View!)` Synchronizes the activated status of view to the last value passed through `RowPresenter.ViewHolder#setActivated(boolean)`. No operation if `RowPresenter.ViewHolder#setActivated(boolean)` is never called. Normally application does not need to call this method, `ListRowPresenter` automatically calls this method when a child is attached to list row. However if application writes its own custom RowPresenter, it should call this method when attaches a child to the row view.
