disposeback to summary
public default void dispose()

Called when this cell is no longer going to be used at all. reset() will have been called before this method is invoked.

Default implementation does nothing.

getNodeback to summary

public default boolean isReusable()

Indicates whether this cell can be reused to display different items.

public default void updateIndex(int index)

Called to update index of a visible cell.

Default implementation does nothing.
