java.lang.Object

com.nhaarman.listviewanimations.itemmanipulation.animateaddition.InsertQueue<T>

public class InsertQueue<T>
extends Object

A class to insert items only when there are no active items. A pending index-item pair can have two states: active and pending. When inserting new items, the .AnimateAdditionAdapter.Insertable#add (int, Object) method will be called directly if there are no active index-item pairs. Otherwise, pairs will be queued until the active list is empty.
