java.lang.Objectit.unimi.dsi.fastutil.doubles.AbstractDouble2LongMap
it.unimi.dsi.fastutil.doubles.AbstractDouble2LongSortedMap
it.unimi.dsi.fastutil.doubles.Double2LongRBTreeMap
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.

This method must check whether the provided key is in the map using containsKey()
. Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
