It takes two `Connection` objects, 'a' and 'b', as input. 'a' must be a statement input or next connection, while 'b' must be a previous connection. The method returns `true` if a connection between the inputs is allowed and `false` otherwise. It's a helper function used specifically for drag checks.\n"]]
