Methods
Modifier and Type	Method and Description
`protected Throwable`	`annotateConnectException(Throwable cause, SocketAddress remoteAddress)` Appends the remote address to the message of the exceptions caused by connection attempt failure.
`void`	`beginRead()` Schedules a read operation that fills the inbound buffer of the first `ChannelInboundHandler` in the `ChannelPipeline`.
`void`	`bind(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.
`protected void`	`closeIfClosed()`
`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.
`protected boolean`	`ensureOpen(ChannelPromise promise)` Deprecated.
`void`	`flush()` Flush out all write operations scheduled via `Channel.Unsafe.write(Object, ChannelPromise)`.
`protected void`	`flush0()`
`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.
`protected Executor`	`prepareToClose()` Prepares to close the `Channel`.
`RecvByteBufAllocator.Handle`	`recvBufAllocHandle()` Return the assigned `RecvByteBufAllocator.Handle` which will be used to allocate `ByteBuf`'s when receiving data.
`void`	`register(EventLoop eventLoop, ChannelPromise promise)` Register the `Channel` of the `ChannelPromise` and notify the `ChannelFuture` once the registration was complete.
`SocketAddress`	`remoteAddress()` Return the `SocketAddress` to which is bound remote or `null` if none is bound yet.
`protected void`	`safeSetFailure(ChannelPromise promise, Throwable cause)` Marks the specified `promise` as failure.
`protected void`	`safeSetSuccess(ChannelPromise promise)` Marks the specified `promise` as success.
`ChannelPromise`	`voidPromise()` Return a special ChannelPromise which can be reused and passed to the operations in `Channel.Unsafe`.
`void`	`write(Object msg, ChannelPromise promise)` Schedules a write operation.

  - write
```
public final void write(Object msg,
         ChannelPromise promise)
```
    Description copied from interface: Channel.Unsafe
    
    Schedules a write operation.
    
    Specified by:
    
    write in interface Channel.Unsafe
  - flush

  - voidPromise
```
public final ChannelPromise voidPromise()
```
    Description copied from interface: Channel.Unsafe
    
    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.
    
    Specified by:
    
    voidPromise in interface Channel.Unsafe
  - ensureOpen
```
@Deprecated
protected final boolean ensureOpen(ChannelPromise promise)
```
    Deprecated.
  - safeSetSuccess
```
protected final void safeSetSuccess(ChannelPromise promise)
```
    Marks the specified promise as success. If the promise is done already, log a message.
  - safeSetFailure
```
protected final void safeSetFailure(ChannelPromise promise,
                  Throwable cause)
```
    Marks the specified promise as failure. If the promise is done already, log a message.
  - closeIfClosed
```

```
  - annotateConnectException
```
protected final Throwable annotateConnectException(Throwable cause,
                                 SocketAddress remoteAddress)

    Appends the remote address to the message of the exceptions caused by connection attempt failure.
  - prepareToClose
```
protected Executor prepareToClose()
```
    Prepares to close the Channel. If this method returns an Executor, the caller must call the Executor.execute(Runnable) method with a task that calls AbstractChannel.doClose() on the returned Executor. If this method returns null, AbstractChannel.doClose() must be called from the caller thread. (i.e. EventLoop)
