Inherited functions

From class Presenter

`Unit`	`cancelAnimationsRecursive(view: View!)` Utility method for removing all running animations on a view.
`Any!`	`getFacet(facetClass: Class<*>!)`
`Unit`	`onBindViewHolder(viewHolder: Presenter.ViewHolder!, item: Any!, payloads: MutableList<Any!>!)` Binds a `View` to an item with a list of payloads.
`Unit`	`setFacet(facetClass: Class<*>!, facetImpl: Any!)` Sets dynamic implemented facet in addition to basic Presenter functions.
`Unit`	`setOnClickListener(holder: Presenter.ViewHolder!, listener: OnClickListener!)` Called to set a click listener for the given view holder. The default implementation sets the click listener on the root view in the view holder. If the root view isn't focusable this method should be overridden to set the listener on the appropriate focusable child view(s).

From class RowPresenter

RowPresenter.ViewHolder!

createRowViewHolder(parent: ViewGroup!)

Called to create a ViewHolder object for a Row. Subclasses will override this method to return a different concrete ViewHolder object.

Unit

dispatchItemSelectedListener(vh: RowPresenter.ViewHolder!, selected: Boolean)

This method is only called from onRowViewSelected(ViewHolder, boolean) onRowViewSelected. The default behavior is to signal row selected events with a null item parameter. A Subclass of RowPresenter having child items should override this method and dispatch events with item information.

Unit

freeze(holder: RowPresenter.ViewHolder!, freeze: Boolean)

Freezes/unfreezes the row, typically used when a transition starts/ends. This method is called by the fragment, it should not call it directly by the application.
