public void add(short id,
       UpHandler handler)

Registers the specified handler to handle messages containing a mux header with the specified mux identifier.

指定者:

add 在接口中 Muxer<UpHandler>

参数:

id - a mux id

handler - a handler for the specified id

另请参阅:

Muxer.add(short, java.lang.Object)

get

public UpHandler get(short id)

Gets the handler registered under the specified id

指定者:

get 在接口中 Muxer<UpHandler>

参数:

id - a mux id

返回:

the handler, or null if no handler is registered under id

另请参阅:

Muxer.get(short)

remove

public void remove(short id)

Unregisters the handler associated with the specifed mux identifier

指定者:

remove 在接口中 Muxer<UpHandler>

从接口复制的说明: Muxer

Gets the handler for messages that have no mux header.

指定者:

getDefaultHandler 在接口中 Muxer<UpHandler>

返回:

the default handler, or null if no default handler has been set

setDefaultHandler

public void setDefaultHandler(UpHandler handler)

从接口复制的说明: Muxer

Sets the handler for messages that have no mux header.

指定者:

setDefaultHandler 在接口中 Muxer<UpHandler>

参数:

up

public java.lang.Object up(Event evt)

Invoked for all channel events except connection management and state transfer.

指定者:

up 在接口中 UpHandler

另请参阅:

UpHandler.up(Event)

handleStateTransferEvent

protected ImmutableReference<java.lang.Object> handleStateTransferEvent(Event evt)

Extension point for subclasses called by up() when an event related to state transfer is received, allowing the subclass to override the default behavior of passing the event to the default up handler.

返回:

an AtomicReference containing the return value for the event if the event was handled and no further processing should be done in up(), or null if up() needs to handle the event. If the event was handled but the return value is null, an AtomicReference initialized to null should be returned. This default implementation always returns null
