How to create a synchronized version of Google Guava TreeMultimap

Question

Does anyone know how to create a thread safe instance of TreeMultimap using TreeMultimap.create() ?

Answer 1

The Guava Multimaps contains static methods for creating and decoding Multimaps, similar to what the Collections class in java.util provides for collections and maps.

In your case, you should use:

 Multimaps.synchronizedSortedSetMultimap(TreeMultimap.create()) 

Answer 2

Similarly, if you need a synchronized version of ListMultiMap , you can use:

 Multimaps.synchronizedListMultimap(ArrayListMultimap.create());
