• Public Property Count: Int property #

  How many values it holds.

• @PanicsAtCaller Public Method AddFirst(value: T) method #

  Puts value at the front. A Deque holds at most 2147483647 values, as many as its Int Count counts, as an array does, and one more panics.

• @PanicsAtCaller Public Method AddLast(value: T) method #

  Puts value at the back. A Deque holds at most 2147483647 values, as many as its Int Count counts, as an array does, and one more panics.

• @PanicsAtCaller Public Method Add(value: T) method #

  The same as AddLast.

• @PanicsAtCaller Public Method AddAll(values: Iterable<T>) method #

  Adds each of the values last, in order.

• @PanicsAtCaller Public Method RemoveFirst(): T method #

  Takes the first value off and gives it. Panics when the Deque is empty.

• @PanicsAtCaller Public Method RemoveLast(): T method #

  Takes the last value off and gives it. Panics when the Deque is empty.

• @PanicsAtCaller Public Method First(): T method #

  The first value, which stays, as everything else does. Panics when the Deque is empty.

• @PanicsAtCaller Public Method Last(): T method #

  The last value, which stays, as everything else does. Panics when the Deque is empty.

• Public Method TryRemoveFirst(): T? method #

  Takes the first value off and gives it, or Null when the Deque is empty.

• Public Method TryRemoveLast(): T? method #

  Takes the last value off and gives it, or Null when the Deque is empty.

• Public Method TryFirst(): T? method #

  The first value, which stays, or Null when the Deque is empty.

• Public Method TryLast(): T? method #

  The last value, which stays, or Null when the Deque is empty.

• @PanicsAtCaller Operator [](index: Int): T operator #

  The value at index, counting from the first, which is 0. Panics unless index is from 0 to Count minus 1.

• @PanicsAtCaller Operator []=(index: Int, value: T) operator #

  Gives the value at index, counting from the first, a new value. Panics unless index is from 0 to Count minus 1.

• Public Method Contains(value: T): Bool method #

  Whether it holds value.

• Public Method ToArray(): T[] method #

  The values from first to last, in a new array.

• Public Method Clear() method #

  Takes every value out.

• Public Static Method DefaultValue(): Deque<T> static method #

  A new, empty Deque.

• Public Method Clone(): Deque<T> method #

  A new Deque with the same values.

• Public Method Iterate(): DequeIterator<T> method #

  The values from first to last. Adding or removing a value while going over them panics.
