    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 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).

    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

    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).

    A1

    the type of the first half of the returned pairs (this is always a supertype of the collection's element type A).

    B

    the type of the second half of the returned pairs

    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 (A1, B) being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That]. is found.

    that

    The iterable providing the second half of each result pair

    bf

    an implicit value of class CanBuildFrom which determines the result class That from the current representation type Repr and the new element type (A1, B).

    returns

    a new collection of type That containing pairs consisting of corresponding elements of this mutable hash map and that. The length of the returned collection is the minimum of the lengths of this mutable hash map and that.

    a new collection of type That containing pairs consisting of corresponding elements of this mutable hash map and that.
