PJ Fanning commented on IO-732:
-------------------------------
created [https://github.com/apache/commons-io/pull/235] as a draft
> Char equivalent of UnsynchronizedByteArrayOutputStream (and InputStream)
> ------------------------------------------------------------------------
>
> Key: IO-732
> URL: https://issues.apache.org/jira/browse/IO-732
> Project: Commons IO
> Issue Type: New Feature
> Components: Streams/Writers
> Affects Versions: 2.8.0
> Reporter: PJ Fanning
> Priority: Major
>
> I was thinking of writing this and submitting it but just want to see if
> people think it makes sense first.
> The idea is to take AbstractByteArrayOutputStream and to replace the byte[]
> with char[] (maybe called AbstractCharArrayWriter) and to create an
> UnsynchronizedCharArrayWriter that extends it. Could so something similar
> with UnsynchronizedByteArrayInputStream - to get an
> UnsynchronizedStringReader.
> The nice thing about AbstractByteArrayOutputStream is the way it avoids
> arraycopy. The existing commons-io StringBuilderWriter still has arraycopy
> under the hood (in the java.lang.StringBuilder).
