Gábor Gyimesi resolved MINIFICPP-1648.
--------------------------------------
Fix Version/s: 0.13.0
Resolution: Fixed
> InputStreamCallback OutputStreamCallback should use Input/OutputStream
> instead of BaseStream

> Key: MINIFICPP-1648
> URL: https://issues.apache.org/jira/browse/MINIFICPP-1648
> Project: Apache NiFi MiNiFi C++
> Issue Type: Improvement
> Reporter: Martin Zink
> Assignee: Gábor Gyimesi
> Priority: Minor
> Labels: MiNiFi-CPP-Hygiene
> Fix For: 0.13.0

> Time Spent: 1h
> Remaining Estimate: 0h

> The current Input/Output callback interfaces use the BaseStream instead of
> the respective InputStream, OutputStream.
> {code:java}
> virtual int64_t InputStreamCallback::process(const
> std::shared_ptr<io::BaseStream>& stream) = 0;
> virtual int64_t OutputStreamCallback::process(const
> std::shared_ptr<io::BaseStream>& stream) = 0;
> {code}
> Ideally it should look like this
> {code:java}
> virtual int64_t InputStreamCallback::process(const
> std::shared_ptr<io::InputStream>& stream) = 0;
> virtual int64_t OutputStreamCallback::process(const
> std::shared_ptr<io::OutputStream>& stream) = 0;
> {code}
> Without this it is impossible to create and use ReadOnly/WriteOnly streams
> for FlowFile IO (the BaseStream requires implementing both the Input and
> Output Stream interfaces)
> However there may be some feature dependent on this solution. (e.g. calling
> write from InputStreamCallback)
