@GwtIncompatible
public java.util.List<T> asJava()
```
 Description copied from interface: Seq
 Creates an immutable List view on top of this Seq, i.e. calling mutators will result in UnsupportedOperationException at runtime.
 The difference to conversion methods toJava*() is that
 
 A view is created in O(1) (constant time) whereas conversion takes O(n) (linear time), with n = collection size.
 
 The operations on a view have the same performance characteristics than the underlying persistent Vavr collection whereas the performance characteristics of a converted collection are those of the Java standard collections.
 
 Please note that our immutable java.util.List view throws UnsupportedOperationException before checking method arguments. Java does handle this case inconsistently.
 Specified by:
 
 asJava in interface Seq<T>
 
 Returns:
 
 A new immutable Collection view on this Traversable.

 Special case: if this traversable is shorter than that elements, and that elements contains duplicates, the resulting traversable may be shorter than the maximum of the lengths of this and that because a traversable contains an element at most once.
 If this Traversable is shorter than that, thisElem values are used to fill the result. If that is shorter than this Traversable, thatElem values are used to fill the result.

 - equals
```
public boolean equals(java.lang.Object o)
```
 Description copied from interface: Traversable
 In Vavr there are four basic classes of collections:
 
 Seq (sequential elements)
 
 Set (distinct elements)
 
 Map (indexed elements)
 
 Multimap (indexed collections)
 
 Two collection instances of these classes are equal if and only if both collections
 
 belong to the same basic collection class (Seq, Set, Map or Multimap)
 
 contain the same elements
 
 have the same element order, if the collections are of type Seq
 
 Two Map/Multimap elements, resp. entries, (key1, value1) and (key2, value2) are equal, if the keys are equal and the values are equal.
 Notes:
 
 No collection instance equals null, e.g. Queue(1) not equals null.
 
 Nulls are allowed and handled as expected, e.g. List(null, 1) equals Stream(null, 1) and HashMap((null, 1)) equals LinkedHashMap((null, 1)).
 
 The element order is taken into account for Seq only. E.g. List(null, 1) not equals Stream(1, null) and HashMap((null, 1), ("a", null)) equals LinkedHashMap(("a", null), (null, 1)). The reason is, that we do not know which implementations we compare when having two instances of type Map, Multimap or Set (see Liskov Substitution Principle).
 
 Other collection classes are equal if their types are equal and their elements are equal (in iteration order).
 
 Iterator equality is defined to be object reference equality.
 Specified by:
 
 equals in interface Traversable<T>
 
 Specified by:
 
 equals in interface Value<T>
 
 Overrides:
 
 equals in class java.lang.Object
 
 Parameters:
 
 o - an object, may be null
 
 Returns:
 
 true, if this collection equals the given object according to the rules described above, false otherwise.
 - hashCode
```
public int hashCode()
```
 Description copied from interface: Traversable
 Returns the hash code of this collection.
 We distinguish between two types of hashes, those for collections with predictable iteration order (like Seq) and those with arbitrary iteration order (like Set, Map and Multimap).
 In all cases the hash of an empty collection is defined to be 1.
 Collections with predictable iteration order are hashed as follows:
 int hash = 1; for (T t : this) { hash = hash * 31 + Objects.hashCode(t); }
 Collections with arbitrary iteration order are hashed in a way such that the hash of a fixed number of elements is independent of their iteration order.
 int hash = 1; for (T t : this) { hash += Objects.hashCode(t); }
 Please note that the particular hashing algorithms may change in a future version of Vavr.
 Generally, hash codes of collections aren't cached in Vavr (opposed to the size/length). Storing hash codes in order to reduce the time complexity would increase the memory footprint. Persistent collections are built upon tree structures, it allows us to implement efficient memory sharing. A drawback of tree structures is that they make it necessary to store collection attributes at each tree node (read: element).
 The computation of the hash code is linear in time, i.e. O(n). If the hash code of a collection is re-calculated often, e.g. when using a List as HashMap key, we might want to cache the hash code. This can be achieved by simply using a wrapper class, which is not included in Vavr but could be implemented like this:
 public final class Hashed<K> { private final K key; private final Lazy<Integer> hashCode; public Hashed(K key) { this.key = key; this.hashCode = Lazy.of(() -> Objects.hashCode(key)); } public K key() { return key; } @Override public boolean equals(Object o) { if (o == key) { return true; } else if (key != null && o instanceof Hashed) { final Hashed that = (Hashed) o; return key.equals(that.key); } else { return false; } } @Override public int hashCode() { return hashCode.get(); } @Override public String toString() { return "Hashed(" + (key == null ? "null" : key.toString()) + ")"; } }
