class GenericArray
[source: scala/collection/mutable/GenericArray.scala]
class GenericArray[A](val override length : Int)
extends IndexedSeq[A] with GenericTraversableTemplate[A, GenericArray] with IndexedSeqLike[A, GenericArray[A]]
This class is used internally to implement data structures that are based on resizable arrays.

Value Summary
val array : Array[AnyRef]
Method Summary
def apply (idx : Int) : A
Returns the elements at position `idx`
override def companion : GenericCompanion[GenericArray]
The factory companion object that builds instances of class CC
override def copyToArray [B >: A](xs : Array[B], start : Int, len : Int) : Unit
Fills the given array xs with at most `len` elements of this traversable starting at position `start`. Copying will stop once either the end of the current traversable is reached or `len` elements have been copied or the end of the array is reached.
override def foreach [U](f : (A) => U) : Unit
Apply a function f to all elements of this iterable object.
def update (idx : Int, elem : A) : Unit

Value Details
val array : Array[AnyRef]
Method Details
override def companion : GenericCompanion[GenericArray]
The factory companion object that builds instances of class CC
Overrides
IndexedSeq.companion, GenericTraversableTemplate.companion
def apply(idx : Int) : A
Returns the elements at position `idx`
def update(idx : Int, elem : A) : Unit
Overrides
IndexedSeqLike.update
override def foreach[U](f : (A) => U) : Unit
Apply a function f to all elements of this iterable object.
Parameters
f - A function that is applied for its side-effect to every element. The result (of arbitrary type U) of function `f` is discarded.
Notes
This method underlies the implementation of most other bulk operations. Implementing `foreach` with `iterator` is often suboptimal. So `foreach` should be overridden in concrete collection classes if a more efficient implementation is available.
Overrides
GenericTraversableTemplate.foreach
override def copyToArray[B >: A](xs : Array[B], start : Int, len : Int) : Unit
Fills the given array xs with at most `len` elements of this traversable starting at position `start`. Copying will stop once either the end of the current traversable is reached or `len` elements have been copied or the end of the array is reached.
Parameters
xs - the array to fill.
start - starting index.
len - number of elements to copy
