override def elements : Iterator[Any]
Creates a new iterator over all elements contained in this object.
override final def flatMap [b](f : (Any) => Iterable[b]) : Array[b]

A sub-sequence of len elements starting at index from (non-strict)
protected def slice0 (start : Int, end : Int) : (Int, Int)
Calculate start position and length in source array to be passed to the array copy operation.
override final def stringPrefix : String
Defines the prefix of this object's toString representation.
abstract def subArray (from : Int, end : Int) : AnyRef
override def take (n : Int) : BoxedArray
Returns a sequence consisting only over the first n elements of this sequence, or else the whole sequence, if it has less than n elements. (non-strict)
override def takeWhile (p : (Any) => Boolean) : BoxedArray
Returns the longest prefix of this sequence whose elements satisfy the predicate p.
abstract def unbox (elemClass : Class) : AnyRef
abstract def unbox (elemTag : String) : AnyRef
Convert to Java array.
abstract def update (index : Int, elem : Any) : Unit
Update element at given index
abstract def value : AnyRef
The underlying array value

Method Details
abstract def length : Int
The length of the array
abstract def apply(index : Int) : Any

abstract def update(index : Int, elem : Any) : Unit
Update element at given index
Overrides
Mutable.update
abstract def unbox(elemTag : String) : AnyRef
Convert to Java array.
Parameters
elemTag - Either one of the tags ".N" where N is the name of a primitive type (@see ScalaRunTime), or a full class name.
abstract def unbox(elemClass : Class) : AnyRef
override def isDefinedAt(x : Int) : Boolean
Is this partial function defined for the index x?
Parameters
x - ..
Returns
true, iff x is a legal sequence index.
override def elements : Iterator[Any]
Creates a new iterator over all elements contained in this object.
Returns
the new iterator
abstract def value : AnyRef

def copyFrom(src : AnyRef, from : Int, to : Int, len : Int) : Unit
def copyTo(from : Int, dest : AnyRef, to : Int, len : Int) : Unit
override def copyToArray[B](xs : Array[B], start : Int) : Unit
Fills the given array xs with the elements of this sequence starting at position start.
Parameters
xs - the array to fill.
start - starting index.
Precondition
the array must be large enough to hold all elements.
abstract def subArray(from : Int, end : Int) : AnyRef
override final def map[b](f : (Any) => b) : Array[b]
Returns the sequence resulting from applying the given function f to each element of this sequence.
Parameters
f - function to apply to each element.
Returns
f(a0), ..., f(an) if this sequence is a0, ..., an.
override final def flatMap[b](f : (Any) => Iterable[b]) : Array[b]
