[Java] Class ListHashMap<K, V>

org.codehaus.groovy.util.ListHashMap

All Implemented Interfaces and Traits:: Map

public class ListHashMap
extends Object

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.
