public interface EventDispatcher
```
Event dispatching interface. It allows objects to receive and notify data events (basically String->Object associations) and create notification chains. To ease the usage of this interface, you could define an EventDispatcherImpl attribute called _event (as suggested in EventDispatcherImpl documentation) and cut'n'paste the following default implementation: public EventDispatcher getEventDispatcher() { return _event; } public void attachEventDispatcher(IEventDispatcher e) { _event.attachEventDispatcher(e.getEventDispatcher()); } public void detachEventDispatcher(IEventDispatcher e) { _event.detachEventDispatcher(e.getEventDispatcher()); } public void notifyEvent(String e, Object a) { _event.notifyEvent(e,a); } public Object getEventValue(String n) { return _event.getEventValue(n); } public Set getEvents() { return _event.getEvents(); } public void ignoreEvents() { _event.ignoreEvents(); } public void unIgnoreEvents() { _event.unIgnoreEvents(); } public Object waitEventValue(String n) { return _event.waitEventValue(n); } Deprecated - Used only by I2PTunnel

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`attachEventDispatcher(EventDispatcher iev)`	Attach an EventDispatcher object to the events dispatching chain.
`void`	`detachEventDispatcher(EventDispatcher iev)`	Detach the specified EventDispatcher object from the events dispatching chain.
`EventDispatcher`	`getEventDispatcher()`	Get an object to be used to deliver events (usually `this`, but YMMV).
`Set<String>`	`getEvents()`	Retrieve the names of all the events that have been received
`Object`	`getEventValue(String name)`	Retrieve the value currently associated with the specified event value
`void`	`ignoreEvents()`	Ignore further event notifications
`void`	`notifyEvent(String event, Object args)`	Deliver an event
`void`	`unIgnoreEvents()`	Almost like the method above :-)
`Object`	`waitEventValue(String name)`	Wait until the given event has received a value

- Method Detail
  - getEventDispatcher
```
EventDispatcher getEventDispatcher()
```
    Get an object to be used to deliver events (usually this, but YMMV).
  - attachEventDispatcher
```
void attachEventDispatcher(EventDispatcher iev)
```
    Attach an EventDispatcher object to the events dispatching chain. Note that notification is not bidirectional (i.e. events notified to ev won't reach the object calling this method). Good luck, and beware of notification loops! :-)
    
    Parameters:
    
    iev - Event object to be attached
  - detachEventDispatcher
```
void detachEventDispatcher(EventDispatcher iev)
```
    Detach the specified EventDispatcher object from the events dispatching chain.
    
    Parameters:
    
    iev - Event object to be detached
  - notifyEvent
```
void notifyEvent(String event,
                 Object args)
```
    Deliver an event
    
    Parameters:
    
    event - name of the event
    
    args - data being stored for that event
  - getEventValue
```
Object getEventValue(String name)
```
    Retrieve the value currently associated with the specified event value
    
    Parameters:
    
    name - name of the event to query for
    
    Returns:
    
    value (or null if none are available)
  - getEvents
```
Set<String> getEvents()
```
    Retrieve the names of all the events that have been received
    
    Returns:
    
    A set of event names
  - ignoreEvents
```
void ignoreEvents()
```
    Ignore further event notifications
  - unIgnoreEvents
```
void unIgnoreEvents()
```
    Almost like the method above :-)
  - waitEventValue
```
Object waitEventValue(String name)
```
    Wait until the given event has received a value
    
    Parameters:
    
    name - name of the event to wait for
    
    Returns:
    
    value specified for that event
