2.  final def ##(): Int

   Equivalent to x.hashCode except for boxed numeric types and null.

   Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

   returns

   a hash value consistent with ==

4.  implicit def IteratorCanBuildFrom[A]: BufferedCanBuildFrom[A, Iterator]

   With the advent of TraversableOnce and Iterator, it can be useful to have a builder which operates on Iterators so they can be treated uniformly along with the collections.

   With the advent of TraversableOnce and Iterator, it can be useful to have a builder which operates on Iterators so they can be treated uniformly along with the collections. See scala.util.Random.shuffle for an example.

5.  def apply[A](elems: A*): Iterator[A]

   Creates an iterator with given elements.

   Creates an iterator with given elements.

   elems

   The elements returned one-by-one from the iterator

   returns

   An iterator which produces the given elements on the first calls to next, and which has no further elements.

6.  final def asInstanceOf[T0]: T0

   Cast the receiver object to be of type T0.

   Cast the receiver object to be of type T0.

   Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

   returns

   the receiver object.

   Definition Classes

   Any

   Exceptions thrown

   ClassCastException if the receiver object is not an instance of the erasure of type T0.

7.  def clone(): AnyRef

   Create a copy of the receiver object.

   Create a copy of the receiver object.

   The default implementation of the clone method is platform dependent.

8.  def continually[A](elem: ⇒ A): Iterator[A]

   Creates an infinite-length iterator returning the results of evaluating an expression.

   Creates an infinite-length iterator returning the results of evaluating an expression. The expression is recomputed for every element.

   elem

   the element computation.

   returns

   the iterator containing an infinite number of results of evaluating elem.

9.  val empty: Iterator[Nothing]

   The iterator which produces no values.

10.  final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (that) is a reference to the receiver object (this).

    Tests whether the argument (that) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.

11.  def equals(arg0: Any): Boolean

    The equality method for reference types. Default implementation delegates to eq.

    returns

13.  def finalize(): Unit

    Called by the garbage collector on the receiver object when there are no more references to the object.

    Called by the garbage collector on the receiver object when there are no more references to the object.

    The details of when and if the finalize method is invoked, as well as the interaction between finalize and non-local returns and exceptions, are all platform dependent.

    Test whether the dynamic type of the receiver object is T0.

    Test whether the dynamic type of the receiver object is T0.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.
