Embed sub diagrams (of all type, especially Mindmap or WBS) in (all type of) diagram

Question

Hello PlantUML team,

From:

• https://forum.plantuml.net/2427/salt-with-minimum-flowchat-capabilities
• https://forum.plantuml.net/6947/embed-sub-diagrams-in-diagram-like-a-note
• https://forum.plantuml.net/9341/embedding-in-interface-note-fails
• https://forum.plantuml.net/10967/order-mismatch-between-note-and-rectangle-with-embedded-salt
• https://forum.plantuml.net/11476/how-to-combine-activity-beta-and-state-diagrams

Then:

• How to insert Mindmap or WBS diagrams in other diagrams?
• Could you improve the sub-diagram or embedded diagram features for all type of diagram?

We don't know what would be the best syntax, like with salt or not:

{{
salt
{
...
}
}}

Here is a little sum-up of existing behavior:

sub-diagram → ↓ host-diagram	Activity	Class	Deployment	Gantt	MindMap	Sequence	State	WBS	Wireframe (salt)
Activity	OK	OK	OK	KO with @startgantt: OK without @startgantt:	KO [Click to see on PlantUML server...]	OK	OK	KO [Click..]
Class (note on class) or Deployment or MindMap	OK	OK	OK	idem	KO	OK	OK	KO	OK
Sequence or State or WBS	OK (on oneline)	OK (on oneline)	OK (on oneline)	idem	KO	OK	OK	KO	OK
Gantt or Wireframe	N/A	N/A	N/A	N/A	N/A	N/A	N/A	N/A	N/A

Thanks for yours works,
Regards,
Th.

With last beta http://beta.plantuml.net/plantuml.jar you can now have :

or:

We did not test all combinaisons... :-)

Hello plantuml,

Marvellous...

FYI, on SVG output, the second example gives a java.lang.NullPointerException:

Thanks for your support,

Hello PlantUML team,

Another open question:

If you allow (no return line before wbs or mindmap and return line mandatory before salt):

@startuml
legend

{{wbs
* root
** level1
** level1
}}

{{mindmap
* root
** level1
** level1
}}

'and

{{
salt
{
[Example button]
[X] Checked box
}
}}

end legend
@enduml

→  Link to PlantUML online server

Could you allow (return line or not) :

{{
wbs
...
}}

or

{{salt
...
}}

?

In order to have a consistent behaviour between salt, wbs or mindmap.

That is an open question, to debate...

Regards,
Th.

Hello, according with the table by The-Lu and the comment from plantuml saying they did not test all combinations, I interpret should be possible to embed a class diagram into a deployment diagram, right?

What I want to do, is to represent an Oracle object-relational database containing types, stored procedures, and object tables. I started trying to plot the ADT (Abstract Data Type, the term used by Oracle for object data types i.e. classes) as a stereotype like this:

@startuml

database "My Object Database" {

    package Types {

{{

    class ParentClass <<ADT>>

}}

    }

}

@enduml

But it's not working, check the link

What I'm doing wrong?

I figured out how to fix my syntax, leaving it here for the posterity in case it helps someone else:

@startuml

database "My Object DB" as n {

    package Types [

        {{

            hide circles

            hide empty fields

            hide empty methods

            class Person <<ADT>>

            class PersonTable <<object table>>

            PersonTable .l. Person : created from >

        }}

    ]

}

@enduml

Here is how it renders (copied from online server enabling dark mode switch there)

Hello D., and all,

In this case even no need for sub-diagrams, see:

@startuml
database "My Object DB" as n {
    package Types {
            hide circles
            hide empty fields
            hide empty methods
            class Person <<ADT>>
            class PersonTable <<object table>>
            PersonTable .l. Person : created from >
    }
}
@enduml

Enjoy,
Regards,
Th.

Ohh! That's much cleaner and elegant! Many thanks @The-Lu!
