LeftOverState

Types

• enum BufferState

  BufferState represents the state of either the inbound, or the outbound EmbeddedChannel buffer. These buffers contain data that travelled the ChannelPipeline all the way.

• struct SynchronousOptions
• struct WrongTypeError

  WrongTypeError is throws if you use readInbound or readOutbound and request a certain type but the first item in the respective buffer is of a different type.

Type members

• init(handler: ChannelHandler?, loop: EmbeddedEventLoop)

  Create a new instance.

• init(handlers: [ChannelHandler], loop: EmbeddedEventLoop)

  Create a new instance.

Instance members

• var allocator: ByteBufferAllocator
• var allowRemoteHalfClosure: Bool
• var closeFuture: EventLoopFuture<Void>
• var embeddedEventLoop: EmbeddedEventLoop

  Returns the EmbeddedEventLoop that this EmbeddedChannel uses. This will return the same instance as EmbeddedChannel.eventLoop but as the concrete EmbeddedEventLoop rather than as EventLoop existential.

• var eventLoop: EventLoop
• var isActive: Bool

  Returns true if the EmbeddedChannel is ‘active’.

• var isWritable: Bool
• var localAddress: SocketAddress?
• let parent: Channel?

  nil because EmbeddedChannels don’t have parents.

• var pipeline: ChannelPipeline
• var remoteAddress: SocketAddress?
• var syncOptions: NIOSynchronousChannelOptions?
• func bind(to: SocketAddress, promise: EventLoopPromise<Void>?)

  Fires the (outbound) bind event through the ChannelPipeline. If the event hits the EmbeddedChannel which happens when it travels the ChannelPipeline all the way to the front, this will also set the EmbeddedChannel’s localAddress.

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

  Fires the (outbound) connect event through the ChannelPipeline. If the event hits the EmbeddedChannel which happens when it travels the ChannelPipeline all the way to the front, this will also set the EmbeddedChannel’s remoteAddress.

• func finish() throws -> LeftOverState

  Synchronously closes the EmbeddedChannel.

• func finish(acceptAlreadyClosed: Bool) throws -> LeftOverState

  Synchronously closes the EmbeddedChannel.

• func getOption<Option>(Option) -> EventLoopFuture<Option.Value>
• func readInbound<T>(as: T.Type) throws -> T?

  If available, this method reads one element of type T out of the EmbeddedChannel’s inbound buffer. If the first element was of a different type than requested, EmbeddedChannel.WrongTypeError will be thrown, if there are no elements in the outbound buffer, nil will be returned.

• func readOutbound<T>(as: T.Type) throws -> T?

  If available, this method reads one element of type T out of the EmbeddedChannel’s outbound buffer. If the first element was of a different type than requested, EmbeddedChannel.WrongTypeError will be thrown, if there are no elements in the outbound buffer, nil will be returned.

• func setOption<Option>(Option, value: Option.Value) -> EventLoopFuture<Void>
• func throwIfErrorCaught() throws

  This method will throw the error that is stored in the EmbeddedChannel if any.

• func writeInbound<T>(T) throws -> BufferState

  Sends an inbound channelRead event followed by a channelReadComplete event through the ChannelPipeline.

• func writeOutbound<T>(T) throws -> BufferState

  Sends an outbound writeAndFlush event through the ChannelPipeline.
