How to create ComponentPort and ComponentExchange for LogicalComponent?

Scripting

Hi All,
I want to create some component ports and component exchanges for lc by p4c, I used the following code:

cp = ComponentPort()
cp.set_name('aaaa')

lc.get_contained_component_ports().add(cp)

but I got some error:

java.lang.UnsupportedOperationException

Anyone knows how to create the componentports and componentexchanges correctly?

The containedComponentPorts feature is derived. To add a port you need to add it as input or output port. There is no Python API provided but you can use the Java API:

lc.get_java_object().setSource(cp.get_java_object())

or

lc.get_java_object().setTarget(cp.get_java_object())

Hello Yvan,

I have the same problem as Jayden, but when I try to use Java API, its functions doesn’t exist. It looks like it is not imported:

org.eclipse.ease.ScriptExecutionException: Traceback (most recent call last):

Can you help me with that please ?

Thx

The setSource() and setTarget() are on the ComponentExchange not the LogicalComponent itself.

myComponentExchange.get_java_object().setSource(cp.get_java_object())

Then you can add the ComponentExchange to your LogicalComponent for instance:

lc.get_java_object().getOwnedComponentExchanges().add(myComponentExchange.get_java_object())
