Hello,
I need some guidance in finding the HasTypeDefinition information.
For example: I have a server with a node, “nodeA”( ns =3, s= nodeA) of type “nodeAType”(ns=2,s=nodeAType).
I am working trying to extract this information and namespace index of the type.
i.e I need the “nodeAType” and the namespace(ns =0) information. Currently, I have the information of nodeA.
Could you guide me here please?
Regards,
Rak

Hello,
Are you looking for the TypeDefinition on the Client side or the Server side? In either case, I’m assuming you’re using the Prosys OPC UA SDK for Java to get it.
On the Client side, you can use UaClient.getAddressSpace().getTypeDefinition(NodeId nodeId) to get the NodeId of the TypeDefinition of the Node with the NodeId used as the input of the method.
On the Server side, you can use UaServer.getAddressSpace().getNode(NodeId nodeId) to first get the Node with the known NodeId, then cast it to UaInstance and use UaInstance.getTypeDefinitionId() to get the NodeId of the TypeDefinition.
