---------------------------------------
Summary: 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
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}
