CASE Switch Variable (Start) (deprecated)

This nodes takes the flow variables from the input port and moves it to exactly one active output branch.

NOTE - Due to the way in which flow variables are handled within KNIME, the flow variable values for any existing flow variables beyond the corresponding "end" node will always be those at the top-most port of the "end" node. New variables created in any active branch will retain their correct values. If you need to change the value of existing variables, please either use a new flow variable, or use a Variable to Table Row node before a conventional End CASE node.

This node is derived from the Vernalis community extension .
