构造器详细资料

CombinedChannelDuplexHandler

protected CombinedChannelDuplexHandler()

Creates a new uninitialized instance. A class that extends this handler must invoke init(ChannelInboundHandler, ChannelOutboundHandler) before adding this handler into a ChannelPipeline.

CombinedChannelDuplexHandler

public CombinedChannelDuplexHandler(I inboundHandler,
                                    O outboundHandler)

Creates a new instance that combines the specified two handlers into one.

方法详细资料

init

protected final void init(I inboundHandler,
                          O outboundHandler)

Initialized this handler with the specified handlers.

抛出:

java.lang.IllegalStateException - if this handler was not constructed via the default constructor or if this handler does not implement all required handler interfaces

java.lang.IllegalArgumentException - if the specified handlers cannot be combined into one due to a conflict in the type hierarchy

inboundHandler

outboundHandler

protected final O outboundHandler()

removeInboundHandler

public final void removeInboundHandler()

Removes the ChannelInboundHandler that was combined in this CombinedChannelDuplexHandler.

removeOutboundHandler

public final void removeOutboundHandler()

Removes the ChannelOutboundHandler that was combined in this CombinedChannelDuplexHandler.
