Dapeng Sun updated CRYPTO-30:
-----------------------------
Fix Version/s: 1.0.0
> Mutable fields should be private
> --------------------------------
>
> Key: CRYPTO-30
> URL: https://issues.apache.org/jira/browse/CRYPTO-30
> Project: Commons Crypto
> Issue Type: Bug
> Components: Stream
> Affects Versions: 1.0.0
> Reporter: Sebb
> Assignee: Ferdinand Xu
> Fix For: 1.0.0
>
>
> Mutable fields should be private or possibly package-protected, never
> protected or public.
> Once a field is published, it's impossible to ensure that it is properly
> synchronised, and it is impossible to change the implementation without API
> breakage.
> Only constants should be published.
> If there is really a need to access the field externally, this should be done
> through getters/setters, as those allow synchronisation to be added and make
> it easier to change the implementation.
> Also, it's easy to add a getter/setter later if access is found to be needed.
> Don't add one 'just in case' because it cannot easily be removed.
> This observation applies to:
> StreamOutput.out
> CTRCipherInputStream.streamOffset
> CTRCipherOutputStream.streamOffset
> CipherInputStream - lots of protected mutable state
> CipherOutputStream - ditto
