Implementation of
Section titled “Implementation of”get(
index):T|undefined
Defined in: packages/data/src/list/bounded-doubly-linked-list.ts:85
Returns the item at the specified index.
If the index is negative, it counts from the end of the list. If the index
is out of bounds, undefined is returned.
Not uniformly O(1). This member reads as positional access, but only a
random-access backing answers it in constant time. On a linked backing, it
walks from an end, so a loop calling get over every index is quadratic.
Iterate the list, or take a cursor
(ICursorSequence/IBidirectionalCursorSequence), whenever
the access pattern is sequential. Each implementation states its own
complexity.
Parameters
Section titled “Parameters”number
The index of the item to retrieve.
Returns
Section titled “Returns”T | undefined
The item at the specified index, or undefined if the index is
out of bounds.

slice()
Section titled “slice()”slice(
start?,end?):IterableIterator<T>
Defined in: packages/data/src/list/bounded-doubly-linked-list.ts:130
Slice the list to a new list from start to end.
This method does not mutate the original list.
The range is specified by the start and end parameters, which are
inclusive and exclusive, respectively. If start is omitted, it defaults
to 0. If end is omitted, it defaults to the length of the list.
If either start or end is negative, they refer to positions from the
end of the list. For example, -1 refers to the last element, -2 refers
to the second last element, and so on.
If start is greater than or equal to end, the result is an empty
iterator.
If the start index is out of bounds, a RangeError is thrown. If end is
out of bounds, it is clamped to the valid range.
Parameters
Section titled “Parameters”start?
Section titled “start?”number
Optional start index of the range (inclusive).
number
Optional end index of the range (exclusive).
Returns
Section titled “Returns”IterableIterator<T>
An iterator for the elements in the specified range.
Throws
Section titled “Throws”If the start index is out of bounds.
Implementation of
Section titled “Implementation of”splice()
Section titled “splice()”splice(
start,deleteCount?,item?):IterableIterator<T>
Defined in: packages/data/src/list/bounded-doubly-linked-list.ts:97
Change the content of the list by removing or replacing existing elements and/or adding new elements in place.
If the start index is negative, it counts from the end of the list. If the start index is equal to the length of the list, no elements are removed and the items are appended to the end of the list. If the start index is out of bounds, a RangeError is thrown.
If deleteCount is omitted, it defaults to Infinity, meaning all elements
from the start index to the end of the list will be removed. If deleteCount
is greater than the number of elements from start to the end of the list,
it will remove all elements from start to the end of the list. If
deleteCount is 0 or negative, no elements will be removed.
If items are provided, they will be inserted starting at the start index.
Parameters
Section titled “Parameters”number
The index at which to start changing the list.
deleteCount?
Section titled “deleteCount?”number = Infinity
The number of elements to remove from the list. Defaults
to Infinity
T
An optional element to add to the list at the start index.
Returns

An iterable of the removed items.
Throws
Section titled “Throws”If the start index is out of bounds.
Implementation of
Section titled “Implementation of”spliceAll()
Section titled “spliceAll()”spliceAll(
start,deleteCount?,items?):IterableIterator<T>
Defined in: packages/data/src/list/bounded-doubly-linked-list.ts:116

start index, keeping their relative order.
Parameters

deleteCount?
Section titled “deleteCount?”number = Infinity
The number of elements to remove from the list. Defaults
