Introduction

Parameters allow to change values and settings of TIS Projects (general parameters) and of operators (parameters of operators)

  • from outside of the project (e.g., TIS Board) and
  • for several operators at once.

Parameters are project-specific, i.e., the scope of a parameter is the project in which it is defined. A parameter from one project is not visible to other projects (however, values can be shared by several projects via TIS Tables).


What kinds of parameters are there?

There are two types of parameters

  1. General parameters (e.g., a text or a number to be entered)
  2. Parameters of operators (e.g., scaling intervals that can be picked out of a list)

 

What are parameters good for?

 

example:

General Parameters

General parameters are of one of the primitive data types available in TIS.

They allow for user input via the TIS Board, e.g., using the [TIS]Board - Recalculate 3.0 operator (including a caption and a helptext)

 Their values can be used (with varying syntax) in different operators, e.g.,

 

Parameters for operation settings

These parameters refer to an operation setting, e.g., the intervals for scaling. They can be made available in the TIS Board by the Controller Portlet. This way

  • operation settings can be changed from the TIS Board,
  • the range of available options can be limited (e.g. users can select days, week, months,..., but not minutes, as scaling intervals), and

  • settings of several operations within a project can be changed together, allowing a more consistent use and an easier interface.

How to change values of parameters?

Parameter values can be changed in two ways:

 Drop Down

Some value types produce specific interfaces (e.g. for date time)

You may restrict the possible values or only allow for some values (e.g. texts in a drop-down menu) 

Please note

Text parameters must not be longer than 4000 characters.

Python

The Python Scripting operator provides information on all parameters
