Lists
append
fun append(T value) > void
Append new element at end of the list
value
: New element
insert
fun insert(int index, T value) > T
Insert new element at index
of the list. If index
is less than 0
, element will be inserted at 0
. If index
is greather than list length, it'll be appended at the end of the list.
index
: Index at which element will be insertedvalue
: New element
Returns: The inserted value
remove
fun remove(int at) > T
Remove element form the list shifting elements after index
at
: Index of element to remove
Returns: Removed element
pop
fun pop() > T?
Remove and return last element of list or null
if list is empty
Returns: Last element
len
fun len() > int
Returns: Length of list
sub
fun sub(int start, int? len) > [T]
Get sub list
start
: Start index of sub listlen
: Length of sub list, ifnull
will go to end of list
Returns: Sub list
indexOf
fun indexOf(T needle) > int?
Search first occurence of the needle
needle
: Element to find
Returns: Index of element or null
if not found
clone
fun clone() > [T]
Returns: Clone of the list
join
fun join(str separator) > str
Join list element in a string with a separator. Elements are converted to a string just like an interpolation would.
separator
: Separator to put between each elements
Returns: Elements joined as a string
forEach
fun forEach(Function callback(int index, T element) > void) > void
Runs callback
for each element of the list.
callback
: Ran for each element
sort
fun sort(Function callback(T left, T right) > bool) > [T]
Stable in-place sort. O(n) best case, O(n*log(n)) worst case and average case.
callback
: Used to compare elements
Returns: The list now sorted
map
fun map::<S>(Function callback(int index, T element) > S) > [S]
Map list to new list of target type by running callback
for each element of the list.
callback
: Ran for each element
Returns: New list of item type S
fill
fun fill(T value) > [T]
Fill the list with value
and returns itself.
value
: Value to fill the list with
Returns: the list
filter
fun filter(Function callback(int index, T element) > bool) > [T]
Filter list keeping element for which callback
returns true
.
callback
: Ran for each element
Returns: Filtered list
reduce
fun reduce::<S>(Function callback(int index, T element, S accumulator) > S, S initial) > S
Reduce list to value of type S
by running callback
with accumulator
being the value being built.
callback
: Ran for each elementinitial
: Initial value
Returns: Reduced value
reverse
fun reverse() > [T]
Returns: A new list with inverted values (e.g. [1, 2, 3]
becomes [3, 2, 1]
)
