"Multi-Port Join Operator?"

GhostriderGhostrider Member Posts: 60 Contributor II
edited June 2019 in Help
I am looking for a join operator, but one that joins multiple ExampleSets based on the ID column instead of only 2.  I know I can cascade the join operators, but looking for a more concise solution.

    Hi Ghostrider,

    I am affraid you need to cascade them. However, this is already on you're feature request list.

    My feature request list?  You want me to implement it?  I can look into it and probably implement it if you give me SVN access.  Seems pretty simple, just replace the InputPortSet with an Extended input-set, then run the existing join algorithm pairs...have not looked at the source code to Join yet...just speculating.

    I can look into implementing it.  Is there a developer's guide for how to commit new operators to SVN?  Is there some checkout procedure?  I've actually never contributed code to any open-source project before.
