public interface DisconnectListener
Interface for a listener interested in connection disconnect events. A disconnect event is fired when either disconnect() or remove() is called on a DatabaseConnections object. When this happens all registered DisconnectListeners will be asked whether we can disconnect, and if we can the process will proceed.
When disconnect or remove is fired (because the user has either selected disconnect or delete for that connection) we will by default disconnect all live connections to the database that have been created with the DatabaseConnections layer.
The user must have requested a disconnect/remove in the first place for this to be called so in general disconnect should always be allowed.
In cases where the disconnect will cause errors, the user should be prompted to terminate whatever is running (e.g. a sql script or debug session) and, only if they say no should the disconnect be blocked.
