## [Java] Class ListHashMap<K, V>

- org.codehaus.groovy.util.ListHashMap

- All Implemented Interfaces and Traits:
    Map

      public class ListHashMap<K, V>
      extends Object
      implements Map

  This class represents a Map that is optimized for a small number of entries. For a number of entries up to `listSize` the entries are stored in arrays. After `listSize` entries are exceeded storage switches internally to a Map and converts back to being array based when its size is less than or equal to `listSize`. Null keys or values are not supported. This class is not thread safe.
