 Description copied from interface: MutableCollection
 Returns a synchronized wrapper backed by this collection. This is the equivalent of using Collections.synchronizedCollection(this) only with a return type that supports the full iteration protocols available on MutableCollection. The preferred way of iterating over a synchronized collection is to use the internal iteration methods which are properly synchronized internally.
```
 MutableCollection synchedCollection = collection.asSynchronized();
 ...
 synchedCollection.forEach(each -> ... );
 synchedCollection.select(each -> ... );
 synchedCollection.collect(each -> ... );
 
```
 If you want to iterate using an imperative style, you must protect external iterators using a synchronized block. This includes explicit iterators as well as JDK 5 style for loops.

```
 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.

 - getFirst
```
public T getFirst()
```
 Description copied from interface: 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 RichIterable<T>
 - getLast
```
public T getLast()
```
 Description copied from interface: 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> MutableCollection<V> flatCollect(Function<? super T,? extends java.lang.Iterable<V>> function)
```
 Description copied from interface: MutableCollection
 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 = Person::getAddresses;
 RichIterable<Person> people = ...;
 
```
 Using collect returns a collection of collections of addresses.
```
 RichIterable<List<Address>> addresses = people.collect(addressFunction);
 
```
 Using flatCollect returns a single flattened list of addresses.
```
 RichIterable<Address> addresses = people.flatCollect(addressFunction);
 
```
 Co-variant example for MutableCollection:
```
 Function<Person, List<Address>> addressFunction = Person::getAddresses;
 MutableCollection<Person> people = ...;
 MutableCollection<List<Address>> addresses = people.collect(addressFunction);
 MutableCollection<Address> addresses = people.flatCollect(addressFunction);
 
```

```
 Multimap<String, Person> peopleByLastName =
 people.groupBy(Person::getLastName);
 
```
 Example using an anonymous inner class:
```
 Multimap<String, Person> peopleByLastName =
 people.groupBy(new Function<Person, String>()
 {
 public String valueOf(Person person)
 {
 return person.getLastName();

 - with
```
public MutableCollection<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<String> 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.

 with in interface MutableCollection<T>
 
 See Also:
 
 Collection.add(Object)
 - without
```
public MutableCollection<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 containing 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<String> 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.

 - withAll
```
public MutableCollection<T> withAll(java.lang.Iterable<? extends T> elements)
```
 Description copied from interface: 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<String> list = list.withAll(FastList.newListWith("1", "2"));
 
```
 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.

 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 containing 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<String> list = list.withoutAll(FastList.newListWith("1", "2"));
 
```
 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.
