Channel

public static interface Channel.Unsafe

Unsafe operations that should never be called from user-code. These methods are only provided to implement the actual transport, and must be invoked from an I/O thread except for the following methods:

• localAddress()
• remoteAddress()
• closeForcibly()
• register(EventLoop, ChannelPromise)
• voidPromise()

方法概要

方法

限定符和类型	方法和说明
void	beginRead() Schedules a read operation that fills the inbound buffer of the first ChannelInboundHandler in the ChannelPipeline.
void	bind(java.net.SocketAddress localAddress, ChannelPromise promise) Bind the SocketAddress to the Channel of the ChannelPromise and notify it once its done.
void	close(ChannelPromise promise) Close the Channel of the ChannelPromise and notify the ChannelPromise once the operation was complete.
void	closeForcibly() Closes the Channel immediately without firing any events.
void	connect(java.net.SocketAddress remoteAddress, java.net.SocketAddress localAddress, ChannelPromise promise) Connect the Channel of the given ChannelFuture with the given remote SocketAddress.
void	deregister(ChannelPromise promise) Deregister the Channel of the ChannelPromise from EventLoop and notify the ChannelPromise once the operation was complete.
void	disconnect(ChannelPromise promise) Disconnect the Channel of the ChannelFuture and notify the ChannelPromise once the operation was complete.
void	flush() Flush out all write operations scheduled via write(Object, ChannelPromise).
java.net.SocketAddress	localAddress() Return the SocketAddress to which is bound local or null if none.
ChannelOutboundBuffer	outboundBuffer() Returns the ChannelOutboundBuffer of the Channel where the pending write requests are stored.
void	register(EventLoop eventLoop, ChannelPromise promise) Register the Channel of the ChannelPromise with the EventLoop and notify the ChannelFuture once the registration was complete.
java.net.SocketAddress	remoteAddress() Return the SocketAddress to which is bound remote or null if none is bound yet.
ChannelPromise	voidPromise() Return a special ChannelPromise which can be reused and passed to the operations in Channel.Unsafe.
void	write(java.lang.Object msg, ChannelPromise promise) Schedules a write operation.

方法详细资料

localAddress

java.net.SocketAddress localAddress()

Return the SocketAddress to which is bound local or null if none.

remoteAddress

java.net.SocketAddress remoteAddress()

Return the SocketAddress to which is bound remote or null if none is bound yet.

register

void register(EventLoop eventLoop,
            ChannelPromise promise)

Register the Channel of the ChannelPromise with the EventLoop and notify the ChannelFuture once the registration was complete.

bind

void bind(java.net.SocketAddress localAddress,
        ChannelPromise promise)

Bind the SocketAddress to the Channel of the ChannelPromise and notify it once its done.

connect

void connect(java.net.SocketAddress remoteAddress,
           java.net.SocketAddress localAddress,
           ChannelPromise promise)

Connect the Channel of the given ChannelFuture with the given remote SocketAddress. If a specific local SocketAddress should be used it need to be given as argument. Otherwise just pass null to it. The ChannelPromise will get notified once the connect operation was complete.

disconnect

void disconnect(ChannelPromise promise)

Disconnect the Channel of the ChannelFuture and notify the ChannelPromise once the operation was complete.

close

void close(ChannelPromise promise)

Close the Channel of the ChannelPromise and notify the ChannelPromise once the operation was complete.

closeForcibly

void closeForcibly()

Closes the Channel immediately without firing any events. Probably only useful when registration attempt failed.

deregister

void deregister(ChannelPromise promise)

Deregister the Channel of the ChannelPromise from EventLoop and notify the ChannelPromise once the operation was complete.

beginRead

void beginRead()

Schedules a read operation that fills the inbound buffer of the first ChannelInboundHandler in the ChannelPipeline. If there's already a pending read operation, this method does nothing.

write

void write(java.lang.Object msg,
         ChannelPromise promise)

Schedules a write operation.

flush

void flush()

Flush out all write operations scheduled via write(Object, ChannelPromise).

voidPromise

ChannelPromise voidPromise()

Return a special ChannelPromise which can be reused and passed to the operations in Channel.Unsafe. It will never be notified of a success or error and so is only a placeholder for operations that take a ChannelPromise as argument but for which you not want to get notified.

outboundBuffer

ChannelOutboundBuffer outboundBuffer()

Returns the ChannelOutboundBuffer of the Channel where the pending write requests are stored.
