ImmutableSortedMap (GS Collections

All Superinterfaces:

InternalIterable<V>, Iterable<V>, MapIterable<K,V>, RichIterable<V>, SortedMapIterable<K,V>

All Known Implementing Classes:

AbstractImmutableSortedMap, ImmutableTreeMap
```
@Immutable
public interface ImmutableSortedMap<K,V>
extends SortedMapIterable<K,V>
```
An ImmutableSortedMap is different than a JCF SortedMap in that it has no mutating methods, but it shares the read-only protocol of a SortedMap.

    Description copied from interface: MapIterable
    
    Given a map from Domain -> Range return a multimap from Range -> Domain. We chose the name 'flip' rather than 'invert' or 'transpose' since this method does not have the property of applying twice returns the original.
    Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.

    Description copied from interface: RichIterable
    Returns a new collection with the results of applying the specified function on each element of the source collection, but only for those elements which return true upon evaluation of the predicate. This is the the optimized equivalent of calling iterable.select(predicate).collect(function).

  - flatCollect
```
<R> ImmutableList<R> flatCollect(Function<? super V,? extends Iterable<R>> function)
```
    Description copied from interface: RichIterable
    flatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection instead. This method is commonly called flatMap.
    Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:
```
 Function<Person, List<Address>> addressFunction = new Function<Person, List<Address>>()
 {
     public List<Address> valueOf(Person person)
     {
         return person.getAddresses();
     }
 };
 MutableList<Person> people = ...;
 
```
    Using collect returns a collection of collections of addresses.
```
 MutableList<List<Address>> addresses = people.collect(addressFunction);
 
```
    Using flatCollect returns a single flattened list of addresses.
```
 MutableList<Address> addresses = people.flatCollect(addressFunction);
 
```
    Specified by:
    
    flatCollect in interface RichIterable<V>
    
    Parameters:
    
    function - The Function to apply
    
    Returns:
    
    a new flattened collection produced by applying the given function
  - zip

    Description copied from interface: RichIterable
    
    Returns a RichIterable formed from this RichIterable and another RichIterable by combining corresponding elements in pairs. If one of the two RichIterables is longer than the other, its remaining elements are ignored.

    Specified by:

    Parameters:
    
    that - The RichIterable providing the second half of each result pair
    
    Returns:
    
    A new RichIterable containing pairs consisting of corresponding elements of this RichIterable and that. The length of the returned RichIterable is the minimum of the lengths of this RichIterable and that.

```
e.g.
 return people.groupBy(new Function<Person, String>()
