Buffer[A]
extends MutableSeq[A] with Collection[A] with Ranged[Int, A]| Type Summary | |
protected final type
|
SortedSelf |
| Method Summary | |
override def
|
+
(a : A) : Buffer
adds "a" from the collection. Useful for chaining.
|
override def
|
-=
(a : A) : Unit
removes "a" from the collection.
|
def
|
add
(idx : Int, a : A) : Unit
Inserts "a" into this buffer just before the element at index "idx."
|
def
|
add (a : A) : Boolean |
def
|
addAll
(idx : Int, that : Iterable[A]) : Unit
Inserts all elements of
that into this buffer just before
the element at index idx. |
final def
|
compare
(k0 : Int, k1 : Int) : Int
Indices are compared through subtraction.
|
override abstract def
|
elements
: BufferIterator[Int, A]
Creates a new iterator over all elements contained in this
object.
|
override def
|
first
: Int
The first index of a buffer is 0.
|
override def
|
isEmpty
: Boolean
Returns true if length == 0
|
override def
|
last
: Int
The last index of a buffer is its size - 1.
|
override def
|
projection
: Projection
returns a facade that can be used to call non-strict
filter,
map, and flatMap methods that build projections
of the collection. |
override def
|
rangeImpl
(from : Option[Int], until : Option[Int]) : Buffer[A]
Creates a ranged projection of this collection. Any mutations in the
ranged projection will update this collection and vice versa. Note: keys
are not garuanteed to be consistent between this collection and the projection.
This is the case for buffers where indexing is relative to the projection.
|
def
|
remove
(idx : Int) : A
Removes the element at index "idx"
|
def
|
set
(idx : Int, a : A) : A
Replaces the element at index "idx" with "a."
|
override def
|
transform
(f : (A) => A) : Boolean
Transforms each element of the collection in-place according to
f. |
def
|
update
(idx : Int, a : A) : Unit
Equivalent to set except the replaced element is not returned.
