PseudoSession | NodeOPCUA reference documentation

Pseudo session is an helper object that exposes the same async methods than the ClientSession. It can be used on a server address space.

Code reused ! The primary benefit of this object is that its makes advanced OPCUA operations that uses browse, translate, read, write etc similar whether we work inside a server or through a client session.
