    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.

    [use case]

    Returns a new synchronized priority queue containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the synchronized priority queue is the most specific superclass encompassing the element types of the two operands.

    Example:

    scala> val a = LinkedList(1)
    a: scala.collection.mutable.LinkedList[Int] = LinkedList(1)
    
    scala> val b = LinkedList(2)
    b: scala.collection.mutable.LinkedList[Int] = LinkedList(2)
    
    scala> val c = a ++ b
    c: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)
    
    scala> val d = LinkedList('a')
    d: scala.collection.mutable.LinkedList[Char] = LinkedList(a)
    
    scala> val e = c ++ d
    e: scala.collection.mutable.LinkedList[AnyVal] = LinkedList(1, 2, a)
    B

    the element type of the returned collection.

    that

    the traversable to append.

    returns

    a new synchronized priority queue which contains all elements of this synchronized priority queue followed by all elements of that.

  7. def ++:[B >: A, That](that: collection.Traversable[B])(implicit bf: CanBuildFrom[PriorityQueue[A], B, That]): That

    As with ++, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

    As with ++, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

    It differs from ++ in that the right operand determines the type of the resulting collection rather than the left one. Mnemonic: the COLon is on the side of the new COLlection type.

    Example:

    scala> val x = List(1)
    x: List[Int] = List(1)
    
    scala> val y = LinkedList(2)
    y: scala.collection.mutable.LinkedList[Int] = LinkedList(2)
    
    scala> val z = x ++: y
    z: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)

    This overload exists because: for the implementation of ++: we should reuse that of ++ because many collections override it with more efficient versions.

    Since TraversableOnce has no ++ method, we have to implement that directly, but Traversable and down can use the overload.

    B

    the element type of the returned collection.

    That

    the class of the returned collection. Where possible, That is the same class as the current collection class Repr, but this depends on the element type B being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, B, That] is found.

    that

    the traversable to append.

    bf

    an implicit value of class CanBuildFrom which determines the result class That from the current representation type Repr and and the new element type B.

    returns

    a new collection of type That which contains all elements of this synchronized priority queue followed by all elements of that.

  20. def aggregate[B](z: B)(seqop: (B, A) ⇒ B, combop: (B, B) ⇒ B): B

    Aggregates the results of applying an operator to subsequent elements.

    Aggregates the results of applying an operator to subsequent elements.

    This is a more general form of fold and reduce. It has similar semantics, but does not require the result to be a supertype of the element type. It traverses the elements in different partitions sequentially, using seqop to update the result, and then applies combop to results from different partitions. The implementation of this operation may operate on an arbitrary number of collection partitions, so combop may be invoked an arbitrary number of times.

    For example, one might want to process some elements and then produce a Set. In this case, seqop would process an element and append it to the list, while combop would concatenate two lists from different partitions together. The initial value z would be an empty set.

    pc.aggregate(Set[Int]())(_ += process(_), _ ++ _)

    Another example is calculating geometric mean from a collection of doubles (one would typically require big doubles for this).

    B

    the type of accumulated results

    z

    the initial value for the accumulated result of the partition - this will typically be the neutral element for the seqop operator (e.g. Nil for list concatenation or 0 for summation)

    seqop

    an operator used to accumulate results within a partition

    combop

    an associative operator used to combine results from different partitions

  21. 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.

  45. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    Tests whether the argument (arg0) 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.

  158. def view(from: Int, until: Int): IterableView[A, PriorityQueue[A]]

    Creates a non-strict view of a slice of this synchronized priority queue.

    Creates a non-strict view of a slice of this synchronized priority queue.

    Note: the difference between view and slice is that view produces a view of the current synchronized priority queue, whereas slice produces a new synchronized priority queue.

    Note: view(from, to) is equivalent to view.slice(from, to)

    from

    the index of the first element of the view

    until

    the index of the element following the view

    returns

    a non-strict view of a slice of this synchronized priority queue, starting at index from and extending up to (but not including) index until.

  163. def withFilter(p: (A) ⇒ Boolean): FilterMonadic[A, PriorityQueue[A]]

    Creates a non-strict filter of this synchronized priority queue.

    Creates a non-strict filter of this synchronized priority queue.

    Note: the difference between c filter p and c withFilter p is that the former creates a new collection, whereas the latter only restricts the domain of subsequent map, flatMap, foreach, and withFilter operations.

    p

    the predicate used to test elements.

    returns

    an object of class WithFilter, which supports map, flatMap, foreach, and withFilter operations. All these operations apply to those elements of this synchronized priority queue which satisfy the predicate p.
