This node allows the creation of flow variables of different types and custom values.
Notes:
- The variables defined by this node take precedence over upstream ones (on the Variable Inport). Thus upstream variables will get overridden by defined variables with the same name and type. The node will notify you in the case this happens.
- It is possible to define variables with the same names but different types as already defined upstream variables. However, keep in mind that this will probably lead to unexpected behavior downstream and should thus be avoided.
- The node will automatically add a variable called “variable_1” when it is initailly created, even before you configure it.
