                    register(promise:)

Register on an EventLoop and so have all its IO handled.

Declaration

Swift

func register(promise: EventLoopPromise<Void>?)

Parameters


                                promise

the EventLoopPromise that will be notified once the operation completes, or nil if not interested in the outcome of the operation.

                    bind(to:promise:)

Bind to a SocketAddress.

Declaration

Swift

func bind(to: SocketAddress, promise: EventLoopPromise<Void>?)

Parameters

`to`	the `SocketAddress` to which we should bind the `Channel`.
`promise`	the `EventLoopPromise` that will be notified once the operation completes, or `nil` if not interested in the outcome of the operation.

                    connect(to:promise:)

Connect to a SocketAddress.

Declaration

Swift

func connect(to: SocketAddress, promise: EventLoopPromise<Void>?)

Parameters

`to`	the `SocketAddress` to which we should connect the `Channel`.
`promise`	the `EventLoopPromise` that will be notified once the operation completes, or `nil` if not interested in the outcome of the operation.

                    write(_:promise:)

Write data to the remote peer.

Be aware that to be sure that data is really written to the remote peer you need to call flush or use writeAndFlush. Calling write multiple times and then flush may allow the Channel to write multiple data objects to the remote peer with one syscall.

Declaration

Swift

func write(_ data: NIOAny, promise: EventLoopPromise<Void>?)

Parameters

`data`	the data to write
`promise`	the `EventLoopPromise` that will be notified once the operation completes, or `nil` if not interested in the outcome of the operation.

                    flush()

Flush data that was previously written via write to the remote peer.

Declaration

Swift

func flush()

                    writeAndFlush(_:promise:)

Shortcut for calling write and flush.

Declaration

Swift

func writeAndFlush(_ data: NIOAny, promise: EventLoopPromise<Void>?)

Parameters

`data`	the data to write
`promise`	the `EventLoopPromise` that will be notified once the `write` operation completes, or `nil` if not interested in the outcome of the operation.

                    read()

Signal that we want to read from the Channel once there is data ready.

If ChannelOptions.autoRead is set for a Channel (which is the default) this method is automatically invoked by the transport implementation, otherwise it’s the user’s responsibility to call this method manually once new data should be read and processed.

Declaration

Swift

func read()

                    close(mode:promise:)

Close the Channel and so the connection if one exists.

Declaration

Swift

func close(mode: CloseMode, promise: EventLoopPromise<Void>?)

Parameters

`mode`	the `CloseMode` that is used
`promise`	the `EventLoopPromise` that will be notified once the operation completes, or `nil` if not interested in the outcome of the operation.

Parameters


                                promise
