Hello,

I try AlarmConditionTypeImpl.isActive(), but this method is not available.
is this a limitation of the sdk or is there a way to enable this method ?

Thanks

Hi,

Um, why do you expect there to be a such method? Your IDE and javadocs will show all the methods there are.

There is no such UA Method for that type in OPC UA, thus no such method was generated on the client side.

Yes, in the server side there is the convinience method ‘public boolean isActive()’, but all that does is basically return is the getActiveStateNode().isId(), thus you can use same in the client side. Technically the server side method is only there for backwards compatibility reasons from the era before our current Codegenerator implementation.

The AlarmConditionType is explained in https://reference.opcfoundation.org/Core/docs/Part9/5.8.2/ (below the tables) “ActiveState/Id when set to True indicates that the situation the Condition is representing currently exists”. And yes, this is in general something you are expected to know or learn by yourself.
