I'm trying to create a class diagram, ()- already means 'interface' I guess the keyword interface is redundant here. example? did I not provide the example?
@startuml
class Camera1
class Camera2
interface Camera ()- Camera1
interface Camera ()- Camera2
@enduml
Anyway
This works OK:
@startuml
Bar()- Foo
@enduml
This has a render error on the left side:
@startuml
Bar1()- Foo
@enduml
And, this has a render error on the left side:
@startuml
Bar12()- Foo
@enduml
etc...
