Inherited types

type Index = Int

For improved readability, the index of a Seq.

For improved readability, the index of a Seq.

Attributes

Inherited from:
IndexingOps
type IndexO = Int

For improved readability, the index of a circular Seq.

For improved readability, the index of a circular Seq.

Note

any value is a valid index, provided that Seq is not empty

Extensions

Extensions

extension [A, CC <: (SeqOps)](ring: CC[A])
def reflectAt(i: IndexO): CC[A]

Reflects the sequence to start at some circular index.

Reflects the sequence to start at some circular index.

Value parameters

i

IndexO

Attributes

Returns

a sequence consisting of all elements reversed and rotated to start at circular index ''i''.

Example
Seq(0, 1, 2).reflectAt() // Seq(0, 2, 1)
def rotateLeft(step: Int): CC[A]

Rotates the sequence to the left by some steps.

Rotates the sequence to the left by some steps.

Value parameters

step

the circular distance between each old and new position

Attributes

Returns

a sequence consisting of all elements rotated to the left by ''step'' places. If ''step'' is negative the rotation happens to the right.

Example
Seq(0, 1, 2).rotateLeft(1) // Seq(1, 2, 0)
def rotateRight(step: Int): CC[A]

Rotate the sequence to the right by some steps.

Rotate the sequence to the right by some steps.

Value parameters

step

the circular distance between each new and old position

Attributes

Returns

a sequence consisting of all elements rotated to the right by ''step'' places. If ''step'' is negative the rotation happens to the left.

Example
Seq(0, 1, 2).rotateRight(1) // Seq(2, 0, 1)
def startAt(i: IndexO): CC[A]

Rotates the sequence to start at some circular index.

Rotates the sequence to start at some circular index.

Value parameters

i

IndexO

Attributes

Returns

a sequence consisting of all elements rotated to start at circular index ''i''. It is equivalent to rotateLeft.

Example
Seq(0, 1, 2).startAt(1) // Seq(1, 2, 0)

Inherited extensions

extension [A, CC <: (SeqOps)](ring: CC[A])
def applyO(i: IndexO): A

Gets the element at some circular index.

Gets the element at some circular index.

Value parameters

i

IndexO

Attributes

Throws
java.lang.ArithmeticException

if Seq is empty

Example
Seq(0, 1, 2).applyO(3) // 0
