sealed class UnrolledBuffer[T] extends AbstractBuffer[T] with Buffer[T] with Seq[T] with SeqOps[T, UnrolledBuffer, UnrolledBuffer[T]] with StrictOptimizedSeqOps[T, UnrolledBuffer, UnrolledBuffer[T]] with EvidenceIterableFactoryDefaults[T, UnrolledBuffer, ClassTag] with Builder[T, UnrolledBuffer[T]] with DefaultSerializable

A buffer that stores elements in an unrolled linked list.

Unrolled linked lists store elements in linked fixed size arrays.

Unrolled buffers retain locality and low memory overhead properties of array buffers, but offer much more efficient element addition, since they never reallocate and copy the internal array.

However, they provide O(n/m) complexity random access, where n is the number of elements, and m the size of internal array chunks.

Ideal to use when:

  • elements are added to the buffer and then all of the elements are traversed sequentially
  • two unrolled buffers need to be concatenated (see concat)

Better than singly linked lists for random access, but should still be avoided for such a purpose.

    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.

  29. def applyOrElse[A1 <: Int, B1 >: T](x: A1, default: (A1) => B1): B1

    Applies this partial function to the given argument when it is contained in the function domain.

    Applies this partial function to the given argument when it is contained in the function domain. Applies fallback function where this partial function is not defined.

    Note that expression pf.applyOrElse(x, default) is equivalent to

    if(pf isDefinedAt x) pf(x) else default(x)

    except that applyOrElse method can be implemented more efficiently. For all partial function literals the compiler generates an applyOrElse implementation which avoids double evaluation of pattern matchers and guards. This makes applyOrElse the basis for the efficient implementation for many operations and scenarios, such as:

    • combining partial functions into orElse/andThen chains does not lead to excessive apply/isDefinedAt evaluation
    • lift and unlift do not evaluate source functions twice on each invocation
    • runWith allows efficient imperative-style combining of partial functions with conditionally applied actions

    For non-literal partial function classes with nontrivial isDefinedAt method it is recommended to override applyOrElse with custom implementation that avoids double isDefinedAt evaluation. This may result in better performance and more predictable behavior w.r.t. side effects.

    x

    the function argument

    default

    returns

    the result of this function or fallback function application.

  30. 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.

  32. def className: String

    Defines the prefix of this object's toString representation.

    Defines the prefix of this object's toString representation.

    It is recommended to return the name of the concrete collection type, but not implementation subclasses. For example, for ListMap this method should return "ListMap", not "Map" (the supertype) or "Node" (an implementation subclass).

    The default implementation returns "Iterable". It is overridden for the basic collection kinds "Seq", "IndexedSeq", "LinearSeq", "Buffer", "Set", "Map", "SortedSet", "SortedMap" and "View".

    returns

    a string representation which starts the result of toString applied to this unrolled buffer. By default the string prefix is the simple name of the collection class unrolled buffer.

  39. def combinations(n: Int): Iterator[UnrolledBuffer[T]]

    Iterates over combinations.

    Iterates over combinations. A _combination_ of length n is a subsequence of the original sequence, with the elements taken in order. Thus, "xy" and "yy" are both length-2 combinations of "xyy", but "yx" is not. If there is more than one way to generate the same subsequence, only one will be returned.

    For example, "xyyy" has three different ways to generate "xy" depending on whether the first, second, or third "y" is selected. However, since all are identical, only one will be chosen. Which of the three will be taken is an implementation detail that is not defined.

    Note: Even when applied to a view or a lazy collection it will always force the elements.

    returns

    An Iterator which traverses the possible n-element combinations of this unrolled buffer.

    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).

    When implementing a custom collection type and refining C to the new type, this method needs to be overridden (the compiler will issue an error otherwise).

    Sorts this unrolled buffer according to a comparison function.

    Note: will not terminate for infinite-sized collections.

    Note: Even when applied to a view or a lazy collection it will always force the elements.

    The sort is stable. That is, elements that are equal (as determined by lt) appear in the same order in the sorted sequence as in the original.

    lt

    the comparison function which tests whether its first argument precedes its second argument in the desired ordering.

    returns

    a unrolled buffer consisting of the elements of this unrolled buffer sorted according to the comparison function lt.

    Returns a scala.collection.Stepper for the elements of this collection.

    Returns a scala.collection.Stepper for the elements of this collection.

    The Stepper enables creating a Java stream to operate on the collection, see scala.jdk.StreamConverters. For collections holding primitive values, the Stepper can be used as an iterator which doesn't box the elements.

    The implicit scala.collection.StepperShape parameter defines the resulting Stepper type according to the element type of this collection.

    Note that this method is overridden in subclasses and the return type is refined to S with EfficientSplit, for example scala.collection.IndexedSeqOps.stepper. For Steppers marked with scala.collection.Stepper.EfficientSplit, the converters in scala.jdk.StreamConverters allow creating parallel streams, whereas bare Steppers can be converted only to sequential streams.

  23. def hasDefiniteSize: Boolean

    Tests whether this unrolled buffer is known to have a finite size.

    Tests whether this unrolled buffer is known to have a finite size. All strict collections are known to have finite size. For a non-strict collection such as Stream, the predicate returns true if all elements have been computed. It returns false if the stream is not yet evaluated to the end. Non-empty Iterators usually return false even if they were created from a collection with a known finite size.

    Note: many collection methods will not work on collections of infinite sizes. The typical failure mode is an infinite loop. These methods always attempt a traversal without checking first that hasDefiniteSize returns true. However, checking hasDefiniteSize can provide an assurance that size is well-defined and non-termination is not a concern.

    returns

    true if this collection is known to have finite size, false otherwise.
