Description copied from interface: com.gs.collections.api.collection.MutableCollection

Creates a new empty mutable version of the same collection type. For example, if this instance is a FastList, this method will return a new empty FastList. If the class of this instance is immutable or fixed size (i.e. SingletonList) then a mutable alternative to the class will be provided.

getFirst

public T getFirst()

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

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.

Specified by:

getFirst in interface com.gs.collections.api.RichIterable<T>

getLast

public T getLast()

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

Returns the last element of an iterable. In the case of a List it is the element at the last index. In the case of any other Collection, it is the last 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 last element could be any element from the Set.

flatCollect

public <V> UnifiedSet<V> flatCollect(com.gs.collections.api.block.function.Function<? super T,? extends java.lang.Iterable<V>> 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);

Returns:

an unmodifiable view of this set

asSynchronized

public com.gs.collections.api.set.MutableSet<T> asSynchronized()

Description copied from interface: com.gs.collections.api.collection.MutableCollection

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

It is imperative that the user manually synchronize on the returned collection when iterating over it using the standard JDK iterator or JDK 5 for loop.

  MutableCollection collection = myCollection.asSynchronized();
     ...
  synchronized(collection)
  {
      Iterator i = c.iterator(); // Must be in the 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.

  MutableCollection collection = myCollection.asSynchronized();
     ...
  collection.forEach(new Procedure()
  {
      public void value(Object each)
      {
          ...
      }
  });
 

The returned collection does not pass the hashCode and equals operations through to the backing collection, but relies on Object's equals and hashCode methods. This is necessary to preserve the contracts of these operations in the case that the backing collection is a set or a list.

The returned collection will be serializable if this collection is serializable.

Specified by:

asSynchronized in interface com.gs.collections.api.collection.MutableCollection<T>

Specified by:

asSynchronized in interface com.gs.collections.api.set.MutableSet<T>

Returns:

a synchronized view of this collection.

with

public UnifiedSet<T> with(T element)

Description copied from interface: com.gs.collections.api.collection.MutableCollection

This method allows mutable and fixed size collections the ability to add elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new element to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection list;
 list = list.with("1");
 list = list.with("2");
 return list;
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by with, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling add on itself.

withAll

public UnifiedSet<T> withAll(java.lang.Iterable<? extends T> iterable)

Description copied from interface: com.gs.collections.api.collection.MutableCollection

This method allows mutable and fixed size collections the ability to add multiple elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new elements to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection list;
 list = list.withAll(FastList.newListWith("1", "2"));
 return list;
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withAll, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling addAll on itself.

without

public UnifiedSet<T> without(T element)

Description copied from interface: com.gs.collections.api.collection.MutableCollection

This method allows mutable and fixed size collections the ability to remove elements from their existing elements. In order to support fixed size a new instance of a collection would have to be returned contaning the elements that would be left from the original collection after calling remove. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

 MutableCollection list;
 list = list.without("1");
 list = list.without("2");
 return list;
 

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by without, and any variables that previously referenced the original collection will need to be redirected to reference the new instance.

In order to use this method properly with mutable and fixed size collections the following approach must be taken:
