`MappedList(XList<S> subject, Function<S,E> mapper)`

Method Summary

Modifier and Type	Method	Description
`boolean`	`applies(Predicate<? super E> predicate)`
`E`	`at(long index)`
`boolean`	`contains(E element)`
`boolean`	`containsAll(XGettingCollection<? extends E> elements)`
`boolean`	`containsId(E element)`	Special version of contains() that guarantees to use identity comparison (" == ") when searching for the given element regardless of the collection's internal logic. This method has the same behavior as `XGettingCollection.containsSearched(Predicate)` with a `Predicate` implementation that checks for object identity.
`boolean`	`containsSearched(Predicate<? super E> predicate)`
`XGettingList<E>`	`copy()`	Creates a true copy of this list which references th same elements in the same order as this list does at the time the method is called.
`<T extends Consumer<? super E>> T`	`copySelection(T target, long... indices)`
`<T extends Consumer<? super E>> T`	`copyTo(T target)`
`long`	`count(E element)`
`long`	`countBy(Predicate<? super E> predicate)`
`<T extends Consumer<? super E>> T`	`distinct(T target)`
`<T extends Consumer<? super E>> T`	`distinct(T target, Equalator<? super E> equalator)`
`Equalator<? super E>`	`equality()`
`boolean`	`equals(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)`	Returns `true` if the passed collection is of the same type as this collection and`this.equalsContent(list, equalator)` yields `true`.
`boolean`	`equalsContent(XGettingCollection<? extends E> samples, Equalator<? super E> equalator)`	Returns `true` if all elements of this list and the passed list are sequentially equal as defined by the passed equalator.
`<T extends Consumer<? super E>> T`	`except(XGettingCollection<? extends E> other, Equalator<? super E> equalator, T target)`
`<T extends Consumer<? super E>> T`	`filterTo(T target, Predicate<? super E> predicate)`
`E`	`first()`
`E`	`get()`	Gets the first element in the collection.
`boolean`	`hasVolatileElements()`	Tells if this collection contains volatile elements. An element is volatile, if it can become no longer reachable by the collection without being removed from the collection.
`XImmutableList<E>`	`immure()`	Provides an instance of an immutable collection type with equal behavior and data as this instance.
`long`	`indexBy(Predicate<? super E> predicate)`
`long`	`indexOf(E element)`
`<T extends Consumer<? super E>> T`	`intersect(XGettingCollection<? extends E> other, Equalator<? super E> equalator, T target)`
`boolean`	`isEmpty()`
`boolean`	`isFull()`	Returns true if the current capacity cannot be increased any more.
`boolean`	`isSorted(Comparator<? super E> comparator)`
`<P extends Consumer<? super E>> P`	`iterate(P procedure)`
`<P extends IndexedAcceptor<? super E>> P`	`iterateIndexed(P procedure)`
`Iterator<E>`	`iterator()`

`ListIterator<E>`	`listIterator()`
`ListIterator<E>`	`listIterator(long index)`
`E`	`max(Comparator<? super E> comparator)`
`long`	`maximumCapacity()`	Returns the maximum amount of elements this carrier instance can contain. The actual value may be depend on the configuration of the concrete instance or may depend only on the implementation of the carrier (meaning it is constant for all instances of the implementation, e.g.
`long`	`maxIndex(Comparator<? super E> comparator)`
`E`	`min(Comparator<? super E> comparator)`
`long`	`minIndex(Comparator<? super E> comparator)`
`boolean`	`nullAllowed()`
`boolean`	`nullContained()`
`OldList<E>`	`old()`
`E`	`peek()`

`XGettingList<E>`	`range(long fromIndex, long toIndex)`
`long`	`remainingCapacity()`	Returns the amount of elements this carrier instance can collect before reaching its maximimum capacity.
`long`	`scan(Predicate<? super E> predicate)`	Iterates through the collection and returns the index of the last element that the passed `Predicate`applied to ("scanning").
`E`	`search(Predicate<? super E> predicate)`
`E`	`seek(E sample)`	Returns the first contained element matching the passed sample as defined by the collection's equality logic or null, if no fitting element is contained.

  - hasVolatileElements
```
public boolean hasVolatileElements()
```
    Description copied from interface: XGettingCollection
    
    Tells if this collection contains volatile elements.
    An element is volatile, if it can become no longer reachable by the collection without being removed from the collection. Examples are WeakReference of SoftReference or implementations of collection entries that remove the element contained in an entry by some means outside the collection.
    Note that WeakReference instances that are added to a a simple (non-volatile) implementation of a collection do NOT make the collection volatile, as the elements themselves (the reference instances) are still strongly referenced.
    
    Specified by:
    
    hasVolatileElements in interface ExtendedCollection<E>
    
    Specified by:
    
    hasVolatileElements in interface XGettingCollection<E>

  - equals
```
public boolean equals(XGettingCollection<? extends E> samples,
                      Equalator<? super E> equalator)
```
    Description copied from interface: XGettingCollection
    
    Returns true if the passed collection is of the same type as this collection andthis.equalsContent(list, equalator) yields true.
    
    Specified by:
    
    equals in interface XGettingCollection<E>
  - equalsContent
```
public boolean equalsContent(XGettingCollection<? extends E> samples,
                             Equalator<? super E> equalator)
```
    Description copied from interface: XGettingCollection
    
    Returns true if all elements of this list and the passed list are sequentially equal as defined by the passed equalator.
    Note that for colletion types that don't have a defined order of elements, this method is hardly usable (as is XGettingCollection.equals(Object) for them as defined in Collection). The core problem of comparing collections that have no defined order is that they aren't really reliably comparable to any other collection.
    
    Specified by:
    
    equalsContent in interface XGettingCollection<E>
    
    equalator - the equalator to use to determine the equality of each element

```
    Specified by:
    
    nullContained in interface XGettingCollection<E>
  - containsId
```
public boolean containsId(E element)
```
    Description copied from interface: XGettingCollection
    
    Special version of contains() that guarantees to use identity comparison (" == ") when searching for the given element regardless of the collection's internal logic.
    This method has the same behavior as XGettingCollection.containsSearched(Predicate) with a Predicate implementation that checks for object identity. The only difference is a performance and usability advantage
    
    Specified by:
    
    containsId in interface XGettingCollection<E>
    
    Parameters:
    
    element - the element to be searched in the collection by identity.
    
    Returns:
    
    whether this collection contains exactely the given element.

```
public E seek(E sample)
```
    Description copied from interface: XGettingCollection
    
    Returns the first contained element matching the passed sample as defined by the collection's equality logic or null, if no fitting element is contained. (For collections using referential equality, this method is basically just a variation of XGettingCollection.contains(Object) with a different return type. For collections with data-dependant equality, the returned element might be the same as the passed one or a data-wise equal one, depending on the content of the collection)
