The returned map will be Serializable if this map is Serializable.public com.gs.collections.api.map.sorted.MutableSortedMap<K,V> asSynchronized()
com.gs.collections.api.map.MutableMapIterable
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.

collect returns a collection of collections of addresses.

Conceptually similar to RichIterable.toSet().RichIterable.toList() but retains the original order. If an element appears
multiple times in this iterable, the first one will be copied into the result.
