Undefined number of input and output data table

Postby mike38 » Wed May 14, 2014 10:08

Hi all,

Is it possible to create a widget with an undetermined number of input and/or output data tables ? Sometimes algorithms determine themselves the number of output data tables.

Thanks in advance,
Mike

You can define a multi input channel to take multiple inputs (for instance this is how the "Test Learners" widget works).

There was similarly an option to add the 'Multiple' flag to the output channels. Technically it still is exists, but is not tested and documented (and I would prefer to remove/replace it entirely). It is also very limited in that it can only be connected to another 'multi input channel'.
Instead maybe you could simply output a list of Tables and have another simple widget to select a table from that list.
