The Switch node is useful when you have to test for several different outcomes of a certain variable. A Switch node is meaningless without one or more subnodes. The subnodes must be added manually. There are two different node types you can add to a Switch node:
-
– Specifies case values that should be compared to the switch value.
-
– Specifies the case that none of the case values are equal to the switch value.
Insert a switch node as follows:
-
In the form, ( > > ), in the lower pane, right-click the node, point to and select .
A new node is added to the bottom of the modeling tree. If you want to insert a node into a particular position in the tree, drag it from the node list displayed on the left.
-
In the field, describe in plain words what the Switch node does.
-
In the field, select the switch value that will be compared to the case values defined in the switch node's subnodes.
-
Click to test the code syntax.
-
Click OKto save the code.
-
Add one or more subnodes to the Switch node:
Right-click and select to add a or subnode.
Note You can add as many Case nodes as you like, but it only makes sense to add one or zero Default nodes.
-
Define the actions that will be performed by each node and subnode until your Switch node is complete.
