--------------------------------------
Summary: 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
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)
