How to implement a AttributeHistoryServiceSet in OPC UA Server

[zhanglc]

Hi ,

I want to use milo to implement an opc ua server , in which I can mock some history data.

Looked at the milo code and it seems that I need to implement an AttributeHistoryServiceSet , and then set in the OpcUaServer, when the client call, the subclass of AttributeHistoryServiceSet will return data , which is mocked.

How do I do it? Is there some tutorial here?

Any tips would be greatly appreciated.

In your Namespace or AddressSpace implementation you would just implement/override the default implementations of AttributeHistoryServices::historyRead and AttributeHistoryServices::historyUpdate https://github.com/eclipse/milo/blob/3419235853491ac89f3391bffd337c8200522522/opc-ua-sdk/sdk-server/src/main/java/org/eclipse/milo/opcua/sdk/server/api/services/AttributeHistoryServices.java#L32-L73)

You should not need to replace the service sets.
