The number of entries that are Bottom.
Static
A map of the given entries, which it takes over: they must not be changed afterward.
A map of the given entries, which it copies.
The keys this map changed relative to the map it shares.
Returns an iterable of key, value pairs for every entry in the map.
Optional
An independent copy, which shares what it can with this one.
Returns an iterable of keys in the map
Whether both lay over the same shared map, so a key neither changed holds the very same value in both.
This map with the entries of other written into it, op combining the values of a key both have, in the order of a Map copied from this one.
