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

This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus the additional key and value. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withKeyValue("new key", "new value");
 

In the case of FixedSizeMap, a new instance will be returned by withKeyValue, 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 put on themselves.

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

This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus all of the additional keys and values. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withAllKeyValues(FastList.newListWith(PairImpl.of("new key", "new value")));
 

In the case of FixedSizeMap, a new instance will be returned by withAllKeyValues, 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 put on themselves.

withoutKey

public com.gs.collections.api.map.MutableMap<K,V> withoutKey(K key)

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

This method allows mutable, fixed size, and immutable maps the ability to remove elements from their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original minus the key and value to be removed. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withoutKey("key");
 

In the case of FixedSizeMap, a new instance will be returned by withoutKey, 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.

In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original minus all of the keys and values to be removed. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

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.

flip

public com.gs.collections.api.multimap.set.MutableSetMultimap<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.

asUnmodifiable

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

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

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.MutableMap<K,V>

Returns:

an unmodifiable view of this map.

asSynchronized

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

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

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.

Returns the first element of an iterable. In the case of a List it is the element at the first index. In the case of any other Collection, it is the first element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the first element could be any element from the Set.

flatCollect

public <R> com.gs.collections.api.collection.MutableCollection<R> flatCollect(com.gs.collections.api.block.function.Function<? super V,? extends java.lang.Iterable<R>> function)

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);

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

Returns all elements of the source collection that return false when evaluating of the predicate. This method is also sometimes called filterNot and is the equivalent of calling iterable.select(Predicates.not(predicate)).

e.g.
 return people.reject(new Predicate<Person>()
 {
     public boolean accept(Person person)
     {
         return person.person.getLastName().equals("Smith");
     }
