Summary: Copy on write list
Key: COLLECTIONS-591
URL: https://issues.apache.org/jira/browse/COLLECTIONS-591
Project: Commons Collections
Issue Type: New Feature
Components: List
Reporter: Radosław Smogura
Priority: Minor
Attachments: copy-on-write-list-v1.diff
Hi all,
In one of my projects I wanted to use copy on write list. I slightly improved
this implementation and thought it would be nice to add it to commons
collections, as I couldn't find something like this.
Implementation details:
- the original list is wrapped with CopyOnWriteList,
- on modifications the original list is copied and copy is used instead,
- for iterators before modification, the cursor index is used and then new
iterator is set on on required position (this can't be done for abstract
collections)
I hope there is no flaw in my designs,
Best regards,
Radek Smogura
