[news.eclipse.modeling.mdt.uml2.uml] Re: Component, Port and Interface

[Christian Hein <hein.@xxxxxxxxxxxxxxxx>]

Hi Kenn,

thanks for your reply. I believe your solution works only if the port 
provides only one interface, but I would like to specify a port that 
provides more than one interface.

Component component = umlfactory.createComponent();
component.setName("ProviderComponent");
		
Interface inter1 = umlfactory.createInterface();
inter1.setName("Provide1");
		
Interface inter2 = umlfactory.createInterface();
inter2.setName("Provide2");		
		
Port port = umlfactory.createPort();
port.setName("ProvidePort");

I can set only one interface as port type with port.setType().
How I get add both interfaces to the provided reference list of the port?

Thanks in advance
Christian
