Def Summary | |
override
|
def
++
(iter: scala.Iterable[A])
: scala.collection.mutable.Buffer[A]
Appends a number of elements provided by an iterable object via its elements method. The identity of the
buffer is returned.
|
override
|
def
++:
(iter: scala.Iterable[A])
: scala.collection.mutable.Buffer[A]
Prepends a number of elements provided by an iterable object via its elements method. The identity of the
buffer is returned.
|
def
+:
(elem: A)
: scala.collection.mutable.Buffer[A]
Prepends a single element to this buffer and return the identity of the buffer. |
|
def
+=
(elem: A)
: scala.Unit
Appends a single element to this buffer and returns the identity of the buffer. |
|
override
|
def
apply
(i: scala.Int)
: A
Returns the i-th element of this ArrayBuffer. |
def
clear
: scala.Unit
Clears the buffer contents. |
|
override
|
def
clone
: scala.collection.mutable.Buffer[A]
Return a clone of this buffer. |
override
|
def
equals
(obj: scala.Any)
: scala.Boolean
Checks if two buffers are structurally identical. |
def
insertAll
(n: scala.Int, iter: scala.Iterable[A])
: scala.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
remove
(n: scala.Int)
: A
Removes the element on a given index position. |
|
override protected
|
def
stringPrefix
: java.lang.String
Defines the prefix of the string representation. |
def
update
(n: scala.Int, newelem: A)
: scala.Unit
Replace element at index n with the new element
newelem .
