> [PATCH] Proposal for a new collection type KeyedBuffer
> ------------------------------------------------------
>
>                 Key: COLLECTIONS-224
>                 URL: http://issues.apache.org/jira/browse/COLLECTIONS-224
>             Project: Commons Collections
>          Issue Type: New Feature
>          Components: Buffer
>    Affects Versions: 3.3
>            Reporter: Mariusz Krzemien
>         Attachments: KeyedPriorityBuffer-patch.txt

>
> Patch contains three new files:
> KeyedPriorityBuffer - class based on PriorityBuffer; with additional support 
> for fast search and remove
> KeyedBuffer - general interface for all buffers containing key-identified 
> elements
> TestKeyedPriorityBuffer - JUnit test cases
> Rationale for introducing new types: I needed a buffer with additional fast 
> search (both get and remove) of elements. I wanted a buffer with search 
> characteristics of a HashMap. But one cannot simply put together a Buffer 
> with a HashMap since the Map needs to have an access to the internal buffer 
> data structures to manage fast remove(key). 
> KeyedPriorityBuffer is mixin of a PriorityBuffer with a internal HashMap 
> managing fast search operations. 
> KeyedBuffer is a general interface for all such buffers supporting key 
> operations. It extends Map rather than Collection since imho it is more 
> natural.
