template<typename Connection>
class opcua::Node< Connection >
High-level node class to access node attribute, browse and populate address space.
The Node API is just a more convenient way of using the free functions in the opcua::services namespace.
Node objects are useful as-is but they do not expose the entire OPC UA protocol. You can get access to the associated NodeId instance with the Node::id() method and apply the native open62541 functions or the free functions in the opcua::services namespace.
