Examples of com.badlogic.gdx.utils.IntMap$MapIterator

org.apache.commons.collections15.MapIterator
An unordered map that uses int keys. This implementation is a cuckoo hash map using 3 hashes, random walking, and a small stash for problematic keys. Null values are allowed. No allocation is done except when growing the table size.

This map performs very fast get, containsKey, and remove (typically O(1), worst case O(log(n))). Put may be a bit slower, depending on hash collisions. Load factors greater than 0.91 greatly increase the chances the map will have to rehash to the next higher POT size. @author Nathan Sweet
