How to use UAttribute

Anonymous's picture
Forums: 

Hello,

In the OCAF white paper (in the "Getting Started" section) included with the documentation, it is written : "You can specialize these attributes using the User attribute. For example, if you need a reflection coefficient, you aggregate a User attribute identified as a reflection coefficient with a Real attribute containing the value of the coefficient (as such, you don’t define a new class)."

Now, how can I do this aggregation without writing a new class ?

Thank you.
