org.codehaus.groovy.util.ListHashMap<K,V>
- All Implemented Interfaces:
Map<K,V>
public class ListHashMap<K,V> extends Object implements Map<K,V>
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.-
