These Hooks are called after the connector's operation has completed.
On Success - If the connector operation completes normally, the On Success Hook is called. Note that if you trap errors in your mode specific Hooks, the operation may be interpreted to be successful.
On Error - If the connector operation fails for some reason the assembly line will first try to call the mode specific Hook (e.g. Iterator/On Error) to handle the error. If the mode specific error Hook is disabled this Hook is called. If both error Hooks are disabled, the assembly line terminates.
