Parameters for Operators allow to restrict the values that can be used in the settings of an operation applying this operator.





Prepare in TIS Editor

  1. Prepare the data and operations in a TIS Editor Data Node.
  2. Select the project in the left pane. Then you will see a "Parameter" tab
  3. Go to the tab "Parameters for operations":



Select the operation

  1. Give the Parameter a unique name that allows to distinguish this Parameter from others in the same project
  2. Define the caption and description that will be used in TIS Board for users.
  3. Select the Parameter



Select which setting should used

E.g. we would like to change Scaling



Select the values allowed and pick one

On the right hand side all possible values are shown. Those marked are shown in field of the defined value. The selected value serves as default value.



Add the Parameter and bind it to a specific operator used in a node

Add the Parameter to the list of Parameters by pressing the "Add Parameter" button below:

Then select the Parameter from the list and press "Add". This brings up a drop-down list of possible nodes and operators to be selected.

A selection of the node and pressing "Save" leads to the binding of the Parameter to the operation.

NOTE: The parameter is bound to an operator applied to a data node, that is, an operation. However, in the configuration interface, an operator and a data node are defined, regardless of how many times this operator is used in the data node. In practice, an operator is only applied once in a data node, so this problem will hardly show up. When the operator is applied more than once, than the behavior of this parameter is not defined.



How to remove a binding of an Parameter to an operation

Go to the place where the binding was made and delete the binding.



Operators that can be addressed


For some operators, e.g. Min/Max, you can specify the range of values that can be entered by users.
