com._1c.g5.v8.bm.common.collections.BmLongHashMap<V>
All Implemented Interfaces:
IBmLongMap<V>
public class BmLongHashMap<V> extends Object implements IBmLongMap<V>
This code is adoption of 'HashMap' from Apache Harmony refactored to support primitive long keys.
This implementation doesn't support removal of entries via itearator.
