StringBuilder

final class StringBuilder extends CharSequence with IndexedSeq[Char] with StringLike[StringBuilder] with Builder[Char, String] with Serializable

A builder for mutable sequence of characters. This class provides an API mostly compatible with java.lang.StringBuilder, except where there are conflicts with the Scala collections API (such as the reverse method.)

    [use case]

    Returns a new growable collection containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the growable collection is the most specific superclass encompassing the element types of the two operands (see example).

    B

    the element type of the returned collection.

    a new collection of type That which contains all elements of this growable collection followed by all elements of that.

  7. def ++[B >: Char, That](that: GenTraversableOnce[B])(implicit bf: CanBuildFrom[StringBuilder, B, That]): That

    Returns a new growable collection containing the elements from the left hand operand followed by the elements from the right hand operand.

    Returns a new growable collection containing the elements from the left hand operand followed by the elements from the right hand operand. The element type of the growable collection is the most specific superclass encompassing the element types of the two operands (see example).

    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 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 the new element type B.

    returns

    a new collection of type That which contains all elements of this growable collection followed by all elements of that.

    TraversableLikeGenTraversableLike
  8. def ++:[B >: Char, That](that: Traversable[B])(implicit bf: CanBuildFrom[StringBuilder, 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.

    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 the new element type B.

  30. def aggregate[B](z: B)(seqop: (B, Char) ⇒ 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)

    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
