Configurable End IF/CASE

An 'Inactive Branch Consumer' which will collect 2 or more inactive branches and provide an active branch if there was an active incoming branch. Additional incoming ports can be added, and the port type changed via the configuration menu on the node. Depending on the port type, different options will be available in the node dialog

Flow Variables - there are no options in this case. The output will always be the first connected branch

Data Table It is possible to combine multiple active inputs, depending on the table specs and node settings

Other port types It is not possible to combine multiple ports. In this case if multiple active inputs are present, only one will be passed through or the node execution will fail depending on the node settings

This node was developed by Vernalis Research . For feedback and more information, please contact knime@vernalis.com
