    • DataTypeDictionaryManager

      public DataTypeDictionaryManager​(org.eclipse.milo.opcua.sdk.server.nodes.UaNodeContext context, String namespaceUri)
      Create a BinaryDataTypeDictionaryManager for an OpcUaBinaryDataTypeDictionary in namespaceUri.

      Note that the namespace URI is that of the dictionary, and is not necessarily the same as the namespace the Nodes created by the manager will reside in, i.e. datatype dictionaries are namespaced independently from the namespaces server Nodes reside in.

      Parameters:
      context - a UaNodeContext. Nodes will be created and added using this context.
      namespaceUri - the namespace URI of the dictionary.
