class diagram in OO programming with API

• I am trying to create a class diagram for an application that I am trying to create within a given framework.
• This framework exposes its own custom API and some of the classes in my design is represented by the classes in the API.
• Some of these classes tend to get pretty complex, so I am faced with the question of how to represent these cl开发者_JS百科asses in my class diagram - or should I even attempt to do that.

To be more specific,

• My application moves artifacts from one server to another.
• The framework I am working on provides classes and methods to represent and communicate with the source and destination server.
• Now, I know that my class diagram needs to account for the representation of the server class and its functions, but how can I do it in my class diagram.

Thank you for your help in advance.

You can make a package for your framework/custom API which contains the classes (from the custom API) you need to link to your own classes. Here's an example:

Hope it helps.
