ListQueue<E> class
List based Queue.
Keeps a cyclic buffer of elements, and grows to a larger buffer when it fills up. This guarantees constant time peek and remove operations, and amortized constant time add operations.
The structure is efficient for any queue or stack usage.

-
Returns
true
if there are no elements in this collection. [...]read-only -
iterator
→ Iterator<

Returns a new
Iterator
that allows iterating the elements of thisIterable
. [...]read-only - last → E

read-only
- length → int
-
Returns the number of elements in the iterable. [...]
read-only
- single → E
-
Checks that this iterable has only one element, and returns that element. [...]

test
. [...]inherited -
fold<
