|
* Generic double ended queue implementation |
|
11
|
|
|
* |
|
12
|
|
|
* This class has a FIFO behavior on add, offer, element, peek, remove & poll methods |
|
13
|
|
|
* |
|
14
|
|
|
* Options: |
|
15
|
|
|
* - Defaults: not allow nulls, allow duplicates, identical comparisons |
|
16
|
|
|
* |
|
17
|
|
|
* It is not recommended to allow nulls since several methods |
|
18
|
|
|
* (element, pollFirst, pollLast, poll, peekFirst, peekLast and peek) |
|
19
|
|
|
* returns null if not found or empty |
|
20
|
|
|
* |
|
21
|
|
|
* It is not recommended to set unique values option, this will search inside the |
|
22
|
|
|
* container on every insert and it could be expensive on large containers |

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
You can also find more detailed suggestions in the “Code” section of your repository.
