Represents a chain of EventDispatcher
objects, which can dispatch
an Event
. The event is dispatched by passing it from one
EventDispatcher
to the next in the chain until the end of chain is
reached. Each EventDispatcher
in the chain can influence the event
path and the event itself. The chain is usually formed by following some
parent - child hierarchy from the root to the event target and appending
all EventDispatcher
objects encountered to the chain.

Value members
Concrete methods
Appends the specified EventDispatcher
to this chain. Returns a
reference to the chain with the appended element.
Appends the specified EventDispatcher
to this chain. Returns a
reference to the chain with the appended element.
The caller shouldn't assume that this EventDispatchChain
remains
unchanged nor that the returned value will reference a different chain
after the call. All this depends on the EventDispatchChain
implementation.
So the call should be always done in the following form:
chain = chain.append(eventDispatcher);
- Value Params
- eventDispatcher
the
EventDispatcher
to append to the chain
- Returns
the chain with the appended event dispatcher

Dispatches the specified event through this EventDispatchChain
.
The return value represents the event after processing done by the chain.
If further processing is to be done after the call the event referenced
by the return value should be used instead of the original event. In the
case the event is fully handled / consumed in the chain the returned
value is null
and no further processing should be done with that
event.

- Value Params

the event to dispatch

Prepends the specified EventDispatcher
to this chain. Returns a
reference to the chain with the prepended element.
Prepends the specified EventDispatcher
to this chain. Returns a
reference to the chain with the prepended element.

after the call. All this depends on the EventDispatchChain
implementation.
So the call should be always done in the following form:

- Value Params
- eventDispatcher
the
EventDispatcher
to prepend to the chain
- Returns
the chain with the prepended event dispatcher
