Hi all, I’m currently working on a new Connection Cache for Java and have stumbled over two things:
The one is the fact, that the PlcDriverManager is a class and not an interface. This makes it problematic for me to have the PlcDriverManager implement the same interface. I could probably override every method, so this is not a big problem. However, having a PlcDriverManager interface would be the cleaner solution. This would require us to change the name of the current PlcDriverManager class to something like DefaultPlcDriverManager… this would be a breaking change. Another is that the getConnection doesn’t return a Future … the main reason for this was the try-with-resources pattern, that automatically closes the PlcConnection returned from getConnection. However, returning a future might be the better option and it would be more like in the other languages. Especially when we’re working with cached connections. Here a client might be waiting a while till it gets a connection handle. This also would be a breaking change. What do you folks think? Chris
