Class BmLongHashSet

java.lang.Object
com._1c.g5.v8.bm.common.collections.BmLongHashSet
All Implemented Interfaces:
IBmLongSet
public class BmLongHashSet extends Object implements IBmLongSet
This code is adoption of 'HashMap' from Apache Harmony refactored to support primitive long keys.
This implementation doesn't support removal of elements via itearator.
