Annotations
@Internal()
abstract def fromItems[T](items: T*)(implicit cT: RType[T]): Coll[T]

Construct a new collection from the given list of arguments.

abstract def fromMap[K, V](m: Map[K, V])(implicit arg0: RType[K], arg1: RType[V]): Coll[(K, V)]

Construct a collection of (K,V) pairs using PairColl representation, in which keys and values are stored as separate unboxed arrays.
Construct a collection of (K,V) pairs using PairColl representation, in which keys and values are stored as separate unboxed arrays.

Annotations
@Internal()
abstract def makePartialView[A, B](source: Coll[A], f: (A) ⇒ B, calculated: Array[Boolean], calculatedItems: Array[B])(implicit arg0: RType[B]): Coll[B]

Create a new view using pre-calculated results of f.
Create a new view using pre-calculated results of f.
source
the collection the view is based on.
f
view function, which transforms each pre-image element to the corresponding image element of the resulting collection
calculated
array of flags marking which element where pre-calculated
calculatedItems
pre-calculated images to be used in the resulting collection so that calculated.length == calculatedItems.length
returns
collection of images of f

Annotations
@Internal()
abstract def makeView[A, B](source: Coll[A], f: (A) ⇒ B)(implicit arg0: RType[B]): Coll[B]

Create a new collection in which every item is executed lazily form the corresponding item of the source collection.
Create a new collection in which every item is executed lazily form the corresponding item of the source collection.
source
collection which is used as the source of items
f
function to compute each item of this collection from the source item This is O(1) operation, all executions of f are delayed until the corresponding item of this collection is needed in some operation.

abstract def outerJoin[K, L, R, O](left: Coll[(K, L)], right: Coll[(K, R)])(l: ((K, L)) ⇒ O, r: ((K, R)) ⇒ O, inner: ((K, (L, R))) ⇒ O)(implicit arg0: RType[K], arg1: RType[O]): Coll[(K, O)]

Performs outer join operation between left and right collections.
Performs outer join operation between left and right collections. This is a restricted version of relational join operation. It expects left and right collections have distinct K values in pairs (otherwise exception is thrown). Under this condition resulting collection has size <= left.size + right.size.
l
projection function executed for each element of left
r
projection function executed for each element of right
inner
projection function which is executed for matching items (K, L) and (K, R) with the same K
returns
collection of (K, O) pairs, where each key comes form either left or right collection and values are produced by projections

abstract def pairColl[A, B](as: Coll[A], bs: Coll[B]): PairColl[A, B]

Constructs a new collection of pairs out of the pair of collections by zipping them.
Constructs a new collection of pairs out of the pair of collections by zipping them. The resulting collection is semantically equivalent to as.zip(bs).
as
collection of first items
bs
collection of second items
returns
an instance of PairColl interface with represents the resulting collection of pairs.
abstract def replicate[T](n: Int, v: T)(implicit arg0: RType[T]): Coll[T]

Creates a new collection by replicating value v.
Creates a new collection by replicating value v.
n
how many times to replicate value v
v
value to replicate
returns
collection of the form (v, v, v, ... v) of n elements.
abstract def unzip[A, B](xs: Coll[(A, B)]): (Coll[A], Coll[B])

Deconstruct collection of (A,B) pairs into pair of collections.
Deconstruct collection of (A,B) pairs into pair of collections. If xs is represented as PairColl, then this is O(1) operation (no data is touched).
abstract def xor(left: Coll[Byte], right: Coll[Byte]): Coll[Byte]

Element-wise xor of two collections.
