Root operator output

edited November 2018 in Help
Hi,

I have a process with nested operators (Loop Example). I have to get an output from root operator. Loop example is a last operator and in XML defenition is

<connect from_op="Loop Examples" from_port="output 1" to_port="result 1"/>
<connect from_op="Loop Examples" from_port="output 2" to_port="result 2"/>
in code I have

IOObject o1 = process.getRootOperator().getOutputPorts().getPortByName("result 1").getAnyDataOrNull(); // or getData()
IOObject o2 = process.getRootOperator().getOutputPorts().getPortByName("result 2").getAnyDataOrNull(); // or getData()
But it throws NullPointerException.

Complete process is defined below.

    If I get data from last operator (Example Loop) from output ports output 1 and output 2, its working fine. But I want to get result 1 and result 2 from root process operator. Any idea?

    Regards,
    John

    Hi John,

    the result ports are actually not ouput ports, but sinks of the inner process of the root operator. Something like this should work:
    process.getRootOperator().getSubprocess(0).getInnerSinks().getPortByIndex(0)
    Best, Marius
