[+] def className : String

The class name of this collection. To be used for converting to string. Collections generally print like this:

 <className>(elem_1, ..., elem_n)

 <className>(elem_1, ..., elem_n)

[+] protected def coll : Iterable [ A ]

[+] def copyToArray ( xs: Array [ B ] , start: Int ) : xs.type

Copy all elements of this collection to array xs, starting at start.

[+] def copyToArray$default$2 : Int

Copy all elements of this collection to array xs, starting at start.

[+] def foldLeft ( z: B ) ( op: (B, A) => B ) : B

Fold left

[+] def foldRight ( z: B ) ( op: (A, B) => B ) : B

Fold right

[+] def foreach ( f: A => Unit ) : Unit

Apply f to each element for tis side effects

[+] def head : A

The first element of the collection.

[+] def indexWhere ( p: A => Boolean ) : Int

The index of the first element in this collection for which p holds.

[+] def isEmpty : Boolean

Is the collection empty?

[+] private def iterator : Iterator [ A ]

[+] def knownSize : Int

[+] def mkString ( sep: String ) : String

A string showing all elements of this collection, separated by string sep.

[+] def size : Int

The number of elements in this collection. Does not terminate for infinite collections.

[+] def to ( fi: FromIterable [ C ] ) : C [ A ]

Given a collection factory fi for collections of type constructor C, convert this collection to one of type C[A]. Example uses:

xs.to(List)
xs.to(ArrayBuffer)

Given a collection factory fi for collections of type constructor C, convert this collection to one of type C[A]. Example uses:

xs.to(List)
xs.to(ArrayBuffer)

[+] def toArray ( implicit evidence$8: ClassTag [ B ] ) : Array [ B ]

Convert collection to array.

[+] override def toString : String

[+] def view : View [ A ]

A view representing the elements of this collection.
