public abstract MutableMap<K,V> clone()
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.

public MutableMap<K,V> asSynchronized()
MutableMap
It is imperative that the user manually synchronize on the returned map when iterating over any of its collection views:
MutableMap map = myMutableMap.asSynchronized(); ... Set set = map.keySet(); // Needn't be in synchronized block ... synchronized(map) { // Synchronizing on map, not set! Iterator i = s.iterator(); // Must be in synchronized block while (i.hasNext()) foo(i.next()); }Failure to follow this advice may result in non-deterministic behavior. The preferred way of iterating over a synchronized collection is to use the collection.forEach() method which is properly synchronized internally.
MutableMap map = myMutableMap.asSynchronized(); ... Set set = map.keySet(); // Needn't be in synchronized block ... Iterate.forEach(set, new Procedure() { public void value(Object each) { ... } });
The returned map will be serializable if the specified map is serializable.

MutableMap
map = map.withoutAllKeys(FastList.newListWith("key1", "key2"));In the case of FixedSizeMap, a new instance will be returned by withoutAllKeys, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling remove on themselves.
