public MutableMap<K,V> clone()
AbstractMutableMap
This implementation creates an empty string buffer, appends a left brace, and iterates over the map's entrySet view, appending the string representation of each map.entry in turn. After appending each entry except the last, the string ", " is appended. Finally a right brace is appended. A string is obtained from the stringbuffer, and returned.

is determined by applying the keyFunction

to each item in

. Any entry in map
that has the same key as an entry in this
