Detailed Description
The iEventCord is an interface provided by an event queue to any event handlers wanting to receive some subclasses of events ASAP in a specified priority, bypassing the queue itself.Events may also optionally be sent to the normal event queue itself if none of the event handlers in the cord handle the event.

Member Function Documentation
| virtual csEventID iEventCord::GetName | ( | ) | const [pure virtual] |
| virtual bool iEventCord::GetPass | ( | ) | const [pure virtual] |
Returns true if events are passed on to the owning event queue if all plugins in the cord return false from HandleEvent().
Implemented in csEventCord.
| virtual int iEventCord::Insert | ( | iEventHandler * | , | |
| int | priority | |||
| ) | [pure virtual] |
Insert an event handler into the cord.
The priority defines when it will receive the event with respect to other registered event handlers. Event handlers with the same priority are handled in a first-come first-served fashion. This is significant since returning true from HandleEvent() will stop further event processing.
Implemented in csEventCord.
| virtual void iEventCord::Remove | ( | iEventHandler * | ) | [pure virtual] |
| virtual void iEventCord::SetPass | ( | bool | ) | [pure virtual] |
Sets whether events are passed along to the owning event queue if all plugins in the cord return false from HandleEvent().
Implemented in csEventCord.
