Hi,
I’m connecting on a OPC-UA Server from a Client GUI and I wish to get the “DisplayName” attribute of a method towards this client.
Is there an easy way to do that?
Thanks in advance and have a nice day.

Hi,

If you have obtained the UaMethod object on the client side, you can get the DisplayName by calling

UaMethod.getDisplayName();

Alternatively, you can just simply read the DisplayName attribute provided that you know the NodeId of the method node

UaClient.readAttribute(methodId, Attributes.DisplayName)

Let us know any further questions that you may have.

Hi Heikki,
first of all, many thanks for your reply.
I’m obtaining the UaMethod in that way: UaClient.getMethod(new QualifiedName(“My_Method_Name”)). Is there a better way to do that?
If I wanted instead to get the NodeId of the method, how should I do? I would have expected to find something like “UaClient.MyObject.MyMethod.getNodeId()”, but I can’t find it. Is there something like this?
Thanks again and many greetings.
Alessandro

Hi Alessandro,

As you have obtained the UaMethod, you can just call .getDisplayName() and receive the value of the DisplayName attribute. Similarly, you can call .getNodeId() if you want to obtain the NodeId of method node.

P.s. There’s no such method as UaClient.getMethod but I’m assuming you meant UaObject.getMethod.
