java.lang.Objectcom.badlogic.gdx.utils.ObjectIntMap<K>
public class ObjectIntMap<K>
An unordered map where the values are ints. This implementation is a cuckoo hash map using 3 hashes, random walking, and a
small stash for problematic keys. Null keys are not 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.
