asUnmodifiable

public com.gs.collections.api.map.sorted.MutableSortedMap<K,V> asUnmodifiable()

Description copied from interface: com.gs.collections.api.map.sorted.MutableSortedMap

Returns an unmodifiable view of this map. This method allows modules to provide users with "read-only" access to internal maps. Any query operations on the returned map that "read through" to this map and attempt to modify the returned map, whether direct or via its iterator, result in an UnsupportedOperationException.

The returned map will be Serializable if this map is Serializable.

Specified by:

asUnmodifiable in interface com.gs.collections.api.map.sorted.MutableSortedMap<K,V>

Returns:

an unmodifiable view of this map.

Specified by:

toImmutable in interface com.gs.collections.api.map.sorted.SortedMapIterable<K,V>

asSynchronized

public com.gs.collections.api.map.sorted.MutableSortedMap<K,V> asSynchronized()

Description copied from interface: com.gs.collections.api.map.sorted.MutableSortedMap

Returns a synchronized (thread-safe) map backed by the specified map. In order to guarantee serial access, it is critical that all access to the backing map is accomplished through the returned map.

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.

flip

public com.gs.collections.api.multimap.sortedset.MutableSortedSetMultimap<V,K> flip()

Description copied from interface: com.gs.collections.api.map.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.

flatCollect

Description copied from interface: com.gs.collections.api.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);

 {
     public boolean accept(Person person)
     {

Description copied from interface: com.gs.collections.api.RichIterable

Zips this RichIterable with its indices.

Specified by:

zipWithIndex in interface com.gs.collections.api.map.sorted.MutableSortedMap<K,V>

Specified by:

zipWithIndex in interface com.gs.collections.api.map.sorted.SortedMapIterable<K,V>

Specified by:

zipWithIndex in interface com.gs.collections.api.RichIterable<V>

Returns:

A new RichIterable containing pairs consisting of all elements of this RichIterable paired with their index. Indices start at 0.

groupBy

public <KK> com.gs.collections.api.multimap.list.MutableListMultimap<KK,V> groupBy(com.gs.collections.api.block.function.Function<? super V,? extends KK> function)

Description copied from interface: com.gs.collections.api.RichIterable

For each element of the iterable, the function is evaluated and the results of these evaluations are collected into a new multimap, where the transformed value is the key and the original values are added to the same (or similar) species of collection as the source iterable.

e.g.
 return people.groupBy(new Function<Person, String>()
 {
     public String value(Person person)
     {
         return person.getFirstName() + " " + person.getLastName();
     }
 });

groupByEach

public <KK> com.gs.collections.api.multimap.list.MutableListMultimap<KK,V> groupByEach(com.gs.collections.api.block.function.Function<? super V,? extends java.lang.Iterable<KK>> function)

Description copied from interface: com.gs.collections.api.RichIterable

Similar to RichIterable.groupBy(Function), except the result of evaluating function will return a collection of keys for each value.

groupByUniqueKey

public <VV> com.gs.collections.api.map.MutableMap<VV,V> groupByUniqueKey(com.gs.collections.api.block.function.Function<? super V,? extends VV> function)

Description copied from interface: com.gs.collections.api.RichIterable

For each element of the iterable, the function is evaluated and he results of these evaluations are collected into a new map, where the transformed value is the key. The generated keys must each be unique, or else an exception is thrown.

public <K2,V2> com.gs.collections.api.map.MutableMap<K2,V2> aggregateInPlaceBy(com.gs.collections.api.block.function.Function<? super V,? extends K2> groupBy,
                                                                      com.gs.collections.api.block.function.Function0<? extends V2> zeroValueFactory,

Description copied from interface: com.gs.collections.api.RichIterable

Applies an aggregate procedure over the iterable grouping results into a Map based on the specific groupBy function. Aggregate results are required to be mutable as they will be changed in place by the procedure. A second function specifies the initial "zero" aggregate value to work with (i.e. new AtomicInteger(0)).

Description copied from interface: com.gs.collections.api.RichIterable

Applies an aggregate function over the iterable grouping results into a map based on the specific groupBy function. Aggregate results are allowed to be immutable as they will be replaced in place in the map. A second function specifies the initial "zero" aggregate value to work with (i.e. Integer.valueOf(0)).
