trait
Buffer[A]
extends Seq[A] with Scriptable[Message[(Location, A)]]| Method Summary | |
def
|
+
(elem : A) : Buffer[A]
Append a single element to this buffer and return
the identity of the buffer.
|
def
|
++
(iter : Iterable[A]) : Buffer[A]
Appends a number of elements provided by an iterable object
via its
elements method. The identity of the
buffer is returned. |
def
|
++
(iter : Iterator[A]) : Buffer[A]
Appends a number of elements provided by an iterator
via its
elements method. The identity of the
buffer is returned. |
def
|
++:
(iter : Iterable[A]) : Buffer[A]
Prepends a number of elements provided by an iterable object
via its
elements method. The identity of the
buffer is returned. |
def
|
++=
(iter : Iterator[A]) : Unit
Appends a number of elements provided by an iterator
|
def
|
++=
(src : Array[A], start : Int, len : Int) : Unit
Appends a number of elements in an array
|
def
|
++=
(iter : Iterable[A]) : Unit
Appends a number of elements provided by an iterable object
via its
elements method. |
abstract def
|
+:
(elem : A) : Buffer[A]
Prepend a single element to this buffer and return
the identity of the buffer.
|
abstract def
|
+=
(elem : A) : Unit
Append a single element to this buffer.
|
def
|
-=
(x : A) : Unit
Removes a single element from this buffer, at its first occurrence.
If the list does not contain that element, it is unchanged
|
def
|
<<
(cmd : Message[(Location, A)]) : Unit
Send a message to this scriptable object.
|
def
|
append
(elems : A*) : Unit
Appends a sequence of elements to this buffer.
|
def
|
appendAll
(iter : Iterable[A]) : Unit
Appends a number of elements provided by an iterable object
via its
elements method. |
abstract def
|
clear
: Unit
Clears the buffer contents.
|
override def
|
clone
: Buffer[A]
Return a clone of this buffer.
|
override def
|
hashCode
: Int
The hashCode method always yields an error, since it is not
safe to use buffers as keys in hash tables.
|
def
|
insert
(n : Int, elems : A*) : Unit
Inserts new elements at the index
n. Opposed to method
update, this method will not replace an element with a
one. Instead, it will insert the new elements at index n. |
abstract def
|
insertAll
(n : Int, iter : Iterable[A]) : Unit
Inserts new elements at the index
n. Opposed to method
update, this method will not replace an element with a
one. Instead, it will insert a new element at index n. |
def
|
prepend
(elems : A*) : Unit
Prepend an element to this list.
|
def
|
prependAll
(iter : Iterable[A]) : Unit
Prepends a number of elements provided by an iterable object
via its
elements method. The identity of the
buffer is returned. |
abstract def
|
remove
(n : Int) : A
Removes the element on a given index position.
|
protected override def
|
stringPrefix
: String
Defines the prefix of the string representation.
|
def
|
trimEnd
(n : Int) : Unit
Removes the last
n elements. |
def
|
trimStart
(n : Int) : Unit
Removes the first
n elements. |
abstract def
|
update
(n : Int, newelem : A) : Unit
Replace element at index
n with the new element
newelem. |
