> Add indexed get to CircularFifoQueue
> ------------------------------------
>
>                 Key: COLLECTIONS-399
>                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-399
>             Project: Commons Collections
>          Issue Type: New Feature
>            Reporter: Sebb
>             Fix For: 4.0

>
> Since the BoundedFifoBuffer is implemented as an array, it should be simple to implement random access to any element of the buffer.
> [This functionality was requested on the Commons user list]
> For example:
> // get nth entry; i.e. get(0) is the same as get()
> // NoSuchElementException if i >= numEntries
> // if i < 0, could either throw an Exception or treat as reverse index from end of buffer
> E get(int i)
> This would also work for the sub-class CircularFifoBuffer.
