XOR constraint in class diagram

How can I create a XOR constraint between two relationships in a class diagram using Astah Community Edition?

Thanks in advance.

Solution

  • Astah does not support {xor} constraint as a model. However, you can use Note and Note Anchor to show it as follows:

    (1) Create a note and input "{xor}" in it.

    (2) Add note anchors between a note and associations.
