java.lang.Objectit.unimi.dsi.fastutil.longs.AbstractLong2LongMap
it.unimi.dsi.fastutil.longs.Long2LongRBTreeMap
A type-specific red-black tree map with a fast, small-footprint implementation.
The iterators provided by the views of this class are type-specific bidirectional iterators.
Moreover, the iterator returned by iterator()
can be safely cast
to a type-specific list iterator.
