clearSource Codeshared actual void clear()

Remove every entry from this map, leaving an empty map with no entries.

cloneSource Codeshared actual MutableMap<Key,Item> clone()

A shallow copy of this collection, that is, a collection with identical elements which does not change if this collection changes. If this collection is immutable, it is acceptable to return a reference to this collection. If this collection is mutable, a newly instantiated collection must be returned.

putSource Codeshared actual Item? put(Key key, Item item)

Add an entry to this map, overwriting any existing entry for the given key, and returning the previous value associated with the given key, if any, or null if no existing entry was overwritten.

Refines MutableMap.put ultimately refines MapMutator.put
removeSource Codeshared actual Item? remove(Key key)

Remove the entry associated with the given key, if any, from this map, returning the value no longer associated with the given key, if any, or null if there was no entry associated with the given key.
