Attributes

Returns: a Table[S] which is made up of a concatenation of the results of invoking f on each row this

Builds a new iterable collection by applying a function to all elements of this iterable collection and using the elements of the resulting collections.

For example:

    def getWords(lines: Seq[String]): Seq[String] = lines.flatMap(line => line.split("\\W+"))

The type of the resulting collection is guided by the static type of this iterable collection. This might cause unexpected results sometimes. For example:

    // lettersOf will return a Seq[Char] of likely repeated letters, instead of a Set
    def lettersOf(words: Seq[String]) = words.flatMap(word => word.toSet)

    // lettersOf2 will return a Set[Char], not a Seq

    // xs will be an Iterable[Int]
    val xs = Map("a" -> List(11, 111), "b" -> List(22, 222)).flatMap(_._2)

    // ys will be a Map[Int, Int]

The resulting collection's type will be guided by the type of iterable collection. For example:

  val xs = List(
             Set(1, 2, 3),
             Set(1, 2, 3)
           ).flatten
  // xs == List(1, 2, 3, 1, 2, 3)

  val ys = Set(
             List(1, 2, 3),
             List(3, 2, 1)

Inherited from:: IterableOps

Applies the given binary operator op to the given initial value z and all elements of this iterable collection.

For each application of the operator, each operand is either an element of this iterable collection, the initial value, or another such application of the operator.

        The order of applications of the operator is unspecified and may be nondeterministic.
        Each element appears exactly once in the computation.

The initial value may be used an arbitrary number of times, but at least once.

If this collection is ordered, then for any application of the operator, the element(s) appearing in the left operand will precede those in the right.

        Note: might return different results for different runs, unless either
        of the following conditions is met: (1) the operator is associative,
        and the underlying collection type is ordered; or (2) the operator is
        associative and commutative. In either case, it is also necessary that the initial value

be a neutral value for the operator, e.g. Nil for List concatenation or 1 for multiplication.

The default implementation in IterableOnce is equivalent to foldLeft but may be overridden for more efficient traversal orders.

Note: will not terminate for infinite-sized collections.

Type parameters

A1: The type parameter for the binary operator, a supertype of A.

Value parameters

op: A binary operator; must be associative for the result to always be the same across runs.
z: An initial value; may be used an arbitrary number of times in the computation of the result; must be a neutral value for op for the result to always be the same across runs.

Attributes

Returns: The result of applying op between all the elements and z, or z if this iterable collection is empty.
Inherited from:: IterableOnceOps

Applies the given binary operator op to the given initial value z and all elements of this iterable collection, going left to right. Returns the initial value if this iterable collection is empty.

"Going left to right" only makes sense if this collection is ordered: then if x,,1,,, x,,2,,, ..., x,,n,, are the elements of this iterable collection, the result is op( op( ... op( op(z, x,,1,,), x,,2,,) ... ), x,,n,,).

If this collection is not ordered, then for each application of the operator, each right operand is an element. In addition, the leftmost operand is the initial value, and each other left operand is itself an application of the operator. The elements of this iterable collection and the initial value all appear exactly once in the computation.

Note: might return different results for different runs, unless the underlying collection type is ordered.

Note: will not terminate for infinite-sized collections.

Type parameters

B: The result type of the binary operator.

Value parameters

op: A binary operator.
z: An initial value.

Attributes

Returns: The result of applying op to z and all elements of this iterable collection, going left to right. Returns z if this iterable collection is empty.
Inherited from:: IterableOnceOps

Applies the given binary operator op to all elements of this iterable collection and the given initial value z, going right to left. Returns the initial value if this iterable collection is empty.

"Going right to left" only makes sense if this collection is ordered: then if x,,1,,, x,,2,,, ..., x,,n,, are the elements of this iterable collection, the result is op(x,,1,,, op(x,,2,,, op( ... op(x,,n,,, z) ... ))).

If this collection is not ordered, then for each application of the operator, each left operand is an element. In addition, the rightmost operand is the initial value, and each other right operand is itself an application of the operator. The elements of this iterable collection and the initial value all appear exactly once in the computation.

Note: might return different results for different runs, unless the underlying collection type is ordered.

Note: will not terminate for infinite-sized collections.

Type parameters

B: The result type of the binary operator.

Value parameters

op: A binary operator.
z: An initial value.

Attributes

Returns: The result of applying op to all elements of this iterable collection and z, going right to left. Returns z if this iterable collection is empty.

Inherited from:: IterableOnceOps

Defines how to turn a given Iterable[A] into a collection of type C.

This process can be done in a strict way or a non-strict way (ie. without evaluating the elements of the resulting collections). In other words, this methods defines the evaluation model of the collection.

Value parameters

coll: the source collection to convert

Attributes

Returns: a new collection of type C containing the elements of coll
Note: 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). In the common case where C =:= CC[A], this can be done by mixing in the scala.collection.IterableFactoryDefaults trait, which implements the method using iterableFactory.

As witnessed by the @uncheckedVariance annotation, using this method might be unsound. However, as long as it is called with an Iterable[A] obtained from this collection (as it is the case in the implementations of operations where we use a View[A]), it is safe.

Applies the given binary operator op to all elements of this iterable collection.

For each application of the operator, each operand is either an element of this iterable collection or another such application of the operator. The order of applications of the operator is unspecified and may be nondeterministic. Each element appears exactly once in the computation.

If this collection is ordered, then for any application of the operator, the element(s) appearing in the left operand will precede those in the right.

        Note: might return different results for different runs, unless either
        of the following conditions is met: (1) the operator is associative,
        and the underlying collection type is ordered; or (2) the operator is
        associative and commutative.

Note: will not terminate for infinite-sized collections.

Type parameters

B: The type parameter for the binary operator, a supertype of A.

Value parameters

If this collection is not ordered, then for each application of the operator, each right operand is an element. In addition, the leftmost operand is the first element of this iterable collection and each other left operand is itself an application of the operator. Each element appears exactly once in the computation.

        Note: might return different results for different runs, unless the
        underlying collection type is ordered or the operator is associative
        and commutative.

Note: will not terminate for infinite-sized collections.

Type parameters

B: The result type of the binary operator, a supertype of A.

        Note: might return different results for different runs, unless either
        of the following conditions is met: (1) the operator is associative,
        and the underlying collection type is ordered; or (2) the operator is
        associative and commutative.

Note: will not terminate for infinite-sized collections.

Type parameters

B: A type parameter for the binary operator, a supertype of A.

Inherited from:: IterableOnceOps

Applies the given binary operator op to all elements of this iterable collection, going right to left.

"Going right to left" only makes sense if this collection is ordered: then if x,,1,,, x,,2,,, ..., x,,n,, are the elements of this iterable collection, the result is op(x,,1,,, op(x,,2,,, op( ... op(x,,n-1,,, x,,n,,) ... ))).

In addition, the rightmost operand is the last element of this iterable collection and each other right operand is itself an application of the operator. Each element appears exactly once in the computation.

        Note: might return different results for different runs, unless the
        underlying collection type is ordered or the operator is associative
        and commutative.

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

Example:

  List(1, 2, 3, 4).scanRight(0)(_ + _) == List(10, 9, 7, 4, 0)

Type parameters

B: the type of the elements in the resulting collection

The size of this iterable collection.

Note: will not terminate for infinite-sized collections.

Attributes

Returns: the number of elements in this iterable collection.
Inherited from:: IterableOnceOps

Compares the size of this iterable collection to the size of another Iterable.

Value parameters

that: the Iterable whose size is compared with this iterable collection's size.

Attributes

Returns

A value x where

     x <  0       if this.size <  that.size
     x == 0       if this.size == that.size
     x >  0       if this.size >  that.size

The method as implemented here does not call size directly; its running time is O(this.size min that.size) instead of O(this.size + that.size). The method should be overridden if computing size is cheap and knownSize returns -1.

Inherited from:

IterableOps

Compares the size of this iterable collection to a test value.

Value parameters

otherSize: the test value that gets compared with the size.

Attributes

Returns

A value x where

     x <  0       if this.size <  otherSize
     x == 0       if this.size == otherSize
     x >  0       if this.size >  otherSize

The default implementation does not call size, which may be arbitrarily expensive. It will use knownSize if nonnegative. Otherwise, it will iterate to compute an element count, with complexity O(size min otherSize). This method should be overridden if computing size is cheap and knownSize returns -1. In that case, the custom implementation should just compare size and otherSize directly.

this.sizeIs <= size    // this.sizeCompare(size) <= 0
this.sizeIs == size    // this.sizeCompare(size) == 0
this.sizeIs != size    // this.sizeCompare(size) != 0
this.sizeIs >= size    // this.sizeCompare(size) >= 0
this.sizeIs > size     // this.sizeCompare(size) > 0

Attributes

Returns: a wrapper that allows size comparisons using operators such as =, and >

Value parameters

size: the number of elements per group
step: the distance between the first elements of successive groups

Attributes

Returns: An iterator producing iterable collections of size size, except the last element (which may be the only element) will be smaller if there are fewer than size elements remaining to be grouped.

List(1, 2, 3, 4, 5, 6).sliding(2, 3) = Iterator(List(1, 2), List(4, 5))
Inherited from:: IterableOps

Groups elements in fixed size blocks by passing a "sliding window" over them (as opposed to partitioning them, as is done in grouped).

Value parameters

size: the number of elements per group

Attributes

Returns: An iterator producing iterable collections of size size, except for a non-empty collection with less than size elements, which returns an iterator that produces the source collection itself as its only element.
See also: scala.collection.Iterator, method sliding
Example: List().sliding(2) = empty iterator

List(1).sliding(2) = Iterator(List(1))

List(1, 2).sliding(2) = Iterator(List(1, 2))

Attributes

Returns: a pair of iterable collections consisting of the first n elements of this iterable collection, and the other elements.
Definition Classes: IterableOps -> IterableOnceOps
Inherited from:: IterableOps

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.

For collections of Int, Short, Byte or Char, an scala.collection.IntStepper is returned
For collections of Double or Float, a scala.collection.DoubleStepper is returned
For collections of Long a scala.collection.LongStepper is returned
For any other element type, an scala.collection.AnyStepper is returned

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.

Type parameters

S: the type of the returned Stepper, determined by the implicit StepperShape
