Daniel Stieglitz updated NIFI-16073:
------------------------------------
Summary: Apply Pattern variable in other places in the code base and make
preexisting pattern variables final (was: Apply Pattern variable other places
in the code base and make prexisting pattern variables final)

> Key: NIFI-16073
> URL: https://issues.apache.org/jira/browse/NIFI-16073
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Daniel Stieglitz
> Assignee: Daniel Stieglitz
> Priority: Minor
>
> This ticket picks up where tickets NIFI-16041 and NIFI-16052 left off in that
> it aims to implement the pattern variable in other places of the code and
> make preexisting ones final.
> In many cases, the use of the pattern variable cleans up a lot of duplicate
> casts for example in
> nifi-extension-bundles/nifi-hadoop-bundle/nifi-hdfs-processors/src/main/java/org/apache/nifi/processors/hadoop/util/OutputStreamWritable
> .java the following snippet is before the pattern variable:
> {code:java}
> if (in instanceof DataInputBuffer) {
> byte[] bytes = ((DataInputBuffer) in).getData();
> int pos = ((DataInputBuffer) in).getPosition();
> int length = ((DataInputBuffer) in).getLength();
> int bytesRemaining = length - pos;{code}
> and after the use of the pattern variable
> {code:java}
> if (in instanceof final DataInputBuffer dataInputBuffer) {
> byte[] bytes = dataInputBuffer.getData();
> int pos = dataInputBuffer.getPosition();
> int length = dataInputBuffer.getLength();{code}
>
