how to add process speficic parameters
Hey guys,
Actually, i'm developing a plugin for RapidMiner.
My problem is, i'm trying to add some parameters that should only be valid for one process and also persistent (e.g. some directories,...)
At first, i thought it would be possible to add some functionality to the ProcessRootOperator (there are already some parameters like the verosity level, logfile, resultfile, sendmail and so on). But i didn't find a solution that works.
I would be glad, if you could give me a hint

Hi Marius,
i don't know how to use the macros.
In the documentation of rapidminer and this forum, i cant find any information. Do you know a source/example where i can get more information?
(What i want to do exactly is, after opening/importing a process file some paths of my plugin shall be set.)
greets,

You can use macros as a kind of global process variables. On execution of an operator, the macros will be evaluated and replaced by their current value. Please have a look at the attached process.

<portSpacing port="source_input 1" spacing="0"/>
<portSpacing port="sink_result 1" spacing="0"/>

</process>
</operator>
</process>
maybe you can use Macros to configure process wide parameters?
Best,
Marius
