There are two copies, the MASTER, this is never touched, I generate this from the initial load.
At some later stage, something gets woken up saying that Network in online. When this happens I want a R/W Network that gets saved separately when the Network goes offline. This file then gets used in two ways, when the app reloads it uses this new copy as the Master and the process repeats. At somepont some other process comes along and updates the main database with the current file, then removes it and the process repeats. It’s not a premature optimisation because I have there that is taking too long, hence the need to do this archiving etc. Once the Network wakes up, I need to start catching updates about which nodes are on and offline etc. All the Best Dave > On 25 Jan 2016, at 16:50, Dave <d...@looktowindward.com> wrote: > > Hi Again, > >> The *easy* way to do a deep copy is in fact to archive the root object and >> unarchive the result. > > Yes, I’ve come to that conclusion myself thinking about it.
