-----------------------------------
Summary: Correct comments for the method Selector.clear
Key: KAFKA-12615
URL: https://issues.apache.org/jira/browse/KAFKA-12615
Project: Kafka
Issue Type: Improvement
Components: build
Reporter: HaiyuanZhao
Assignee: HaiyuanZhao
{code:java}
/**
* Clears all the results from the previous poll. This is invoked by Selector
at the start of
* a poll() when all the results from the previous poll are expected to have
been handled.
* <p>
* SocketServer uses {@link #clearCompletedSends()} and {@link
#clearCompletedSends()} to
* clear `completedSends` and `completedReceives` as soon as they are processed
to avoid
* holding onto large request/response buffers from multiple connections longer
than necessary.
* Clients rely on Selector invoking {@link #clear()} at the start of each
poll() since memory usage
* is less critical and clearing once-per-poll provides the flexibility to
process these results in
* any order before the next poll.
