How to assign default values to parameters of an operation?

[bobhairgrove]

When I create an operation, I can add parameters and adjust their properties. However, there isn't an obvious way to assign a default value, for example to a Boolean type parameter which should have a default value of false.

How to do it?

Hello,
To set default types, go to configuration - preferences - Project default values
Under Operation you can find Parameters default type.

@IrinaNeculita
Thank you, but my question is slightly different:

I need to state a default VALUE for a parameter of a specific operation, not the default TYPE for ALL parameters.

Please reopen this question as it is not solved.

When we create a parameter
from explorer : in property view - we have the default value - there you can set the value
in diagram : operation edition view - add the parameter and on the column value can add the value you want.
Let me know if this is the information you look for.

regards,
Irina

Thank you, now I was able to set the default value in the tree view.

Next question: How to get this to show on the class diagram?
For example, I have this text shown in the Operations pane of the class:

+beginParse(in encoding: string, in is_endian_be: boolean)
+endParse()
(etc.)

I would like to see this:

+beginParse(in encoding: string, in is_endian_be: boolean = false)
+endParse()

Thanks!

I am using Modelio 5.3 on Linux Ubuntu 22.04. The "Edit Operation" dialog does not show any column headers for the parameter attributes, as your example has them.

Here is a screenshot of what I see:

For now is not possible to display the value of a parameter in diagram.
I will send the request to development team.

Thank you for reporting the problem from operation edition window.

Irina.
