- Method Detail
  - with
```
MutableList<T> with(T element)
```
    Description copied from interface: 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.
    Specified by:
    
    with in interface MutableCollection<T>
    
    See Also:
    
    Collection.add(Object)
  - without
```
MutableList<T> without(T element)
```
    Description copied from interface: 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. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling remove on itself.

    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.

MutableList<T> withoutAll(Iterable<? extends T> elements)
```
    Description copied from interface: MutableCollection
    This method allows mutable and fixed size collections the ability to remove multiple 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 removeAll. 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;

```
    In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withoutAll, 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 removeAll on itself.

  - newEmpty
```
MutableList<T> newEmpty()
```
    Description copied from interface: 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.

  - flatCollect
```
<V> MutableList<V> flatCollect(Function<? super T,? extends Iterable<V>> 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);
 
```

    Parameters:
    
    function - The Function to apply
    
    Returns:
    
    a new flattened collection produced by applying the given function
  - distinct
```
MutableList<T> distinct()
```
    Description copied from interface: ListIterable
    
    Returns a new ListIterable containing the distinct elements in this list.
    Conceptually similar to RichIterable.toSet().RichIterable.toList() but retains the original order. If an element appears multiple times in this list, the first one will be copied into the result.
    
    Specified by:
    
    distinct in interface ListIterable<T>
    
    Specified by:
    
    distinct in interface ReversibleIterable<T>
    
    Returns:
    
    ListIterable of distinct elements
  - sortThis
```
MutableList<T> sortThis(Comparator<? super T> comparator)
```
    Sorts the internal data structure of this list and returns the list itself as a convenience.
  - sortThis
```
MutableList<T> sortThis()
```
    Sorts the internal data structure of this list and returns the list itself as a convenience.
  - sortThisBy
```
<V extends Comparable<? super V>> MutableList<T> sortThisBy(Function<? super T,? extends V> function)
```
    Sorts the internal data structure of this list based on the natural order of the attribute returned by function.
  - subList
```
MutableList<T> subList(int fromIndex,
                       int toIndex)
```
    Specified by:
    
    subList in interface List<T>
  - asUnmodifiable
```
MutableList<T> asUnmodifiable()
```
    Returns an unmodifable view of the list. The returned list will be Serializable if this list is Serializable.
    
    Specified by:
    
    asUnmodifiable in interface MutableCollection<T>
    
    Returns:
    
    an unmodifiable view of this list
  - asSynchronized
```
MutableList<T> asSynchronized()
```
    Description copied from interface: 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 MutableCollection<T>
    
    Returns:
    
    a synchronized view of this collection.
  - toImmutable
```
ImmutableList<T> toImmutable()
```
    Returns an immutable copy of this list. If the list is immutable, it returns itself. The returned list will be Serializable if this list is Serializable.

    toImmutable in interface MutableCollection<T>
  - groupBy
```
<V> MutableListMultimap<V,T> groupBy(Function<? super T,? extends V> function)
```
    Description copied from interface: 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();
     }
 });
