public class Opening<T>
extends Event<T>

This event is fired on IOSubchannels that are created by provider components before their first usage for Input or Output events.

The subsequent Opened event (or some specialization) will be sent only after the Opening event has completed. This allows components to set up additional data processing for the newly created IOSubchannel before data is sent to it.
