T - Component type of the Stream.@Deprecated public abstract static class Stream.Cons<T> extends Stream<T>
Stream, consisting of a head, and tail.Stream.Cons<T>, Stream.Empty<T>| Modifier and Type | Method and Description |
|---|---|
boolean |
equals(java.lang.Object o)
Deprecated.
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.

int |
hashCode()
Deprecated.
Returns the hash code of this collection.
|
T |
head()
Deprecated.
Returns the first element of a non-empty Traversable.
|
boolean |
isEmpty()
Deprecated.
Checks if this Traversable is empty.
|
Iterator<T> |
iterator()
Deprecated.
An iterator by means of head() and tail().
|
java.lang.String |
toString()
Deprecated.
Clarifies that values have a proper toString() method implemented.
