DatagramSegmentSize

Types

• struct AllocatorOption

  AllocatorOption allows to specify the ByteBufferAllocator to use.

• struct AllowRemoteHalfClosureOption

  AllowRemoteHalfClosureOption allows users to configure whether the Channel will close itself when its remote peer shuts down its send stream, or whether it will remain open. If set to false (the default), the Channel will be closed automatically if the remote peer shuts down its send stream. If set to true, the Channel will not be closed: instead, a ChannelEvent.inboundClosed user event will be sent on the ChannelPipeline, and no more data will be received.

• struct AutoReadOption

  AutoReadOption allows users to configure if a Channel should automatically call Channel.read again once all data was read from the transport or if the user is responsible to call Channel.read manually.

• struct BacklogOption

  BacklogOption allows users to configure the backlog value as specified in man 2 listen. This is only useful for ServerSocketChannels.

• struct ConnectTimeoutOption

  ConnectTimeoutOption allows users to configure the TimeAmount after which a connect will fail if it was not established in the meantime. May be nil, in which case the connection attempt will never time out.

• enum ConvenienceOptionValue<ValueType>

  Has an option been set? Option has a value of generic type ValueType.

• struct DatagramReceiveOffload

  DatagramReceiveOffload sets the UDP_GRO socket option which allows for datagrams to be accumulated by the kernel (or in some cases, the NIC) and reduces traversals in the kernel’s networking layer.

• struct DatagramVectorReadMessageCountOption

  DatagramVectorReadMessageCountOption allows users to configure the number of messages to attempt to read in a single syscall on a datagram Channel.

• struct ExplicitCongestionNotificationsOption

  When set to true IP level ECN information will be reported through AddressedEnvelope.Metadata

• struct MaxMessagesPerReadOption

  MaxMessagesPerReadOption allows users to configure the maximum number of read calls to the underlying transport are performed before wait again until there is more to read and be notified.

• struct ReceivePacketInfo

  When set to true IP level Packet Info information will be reported through AddressedEnvelope.Metadata for UDP packets.

• struct RecvAllocatorOption

  RecvAllocatorOption allows users to specify the RecvByteBufferAllocator to use.

• struct SocketOption

  SocketOption allows users to specify configuration settings that are directly applied to the underlying socket file descriptor.

• struct WriteBufferWaterMark

  The watermark used to detect when Channel.isWritable returns true or false.

• struct WriteBufferWaterMarkOption

  WriteBufferWaterMarkOption allows users to configure when a Channel should be marked as writable or not. Once the amount of bytes queued in a Channels outbound buffer is larger than WriteBufferWaterMark.high the channel will be marked as non-writable and so Channel.isWritable will return false. Once we were able to write some data out of the outbound buffer and the amount of bytes queued falls below WriteBufferWaterMark.low the Channel will become writable again. Once this happens Channel.writable will return true again. These writability changes are also propagated through the ChannelPipeline and so can be intercepted via ChannelInboundHandler.channelWritabilityChanged.

• struct WriteSpinOption

  WriteSpinOption allows users to configure the number of repetitions of a only partially successful write call before considering the Channel not writable. Setting this option to 0 means that we only issue one write call and if that call does not write all the bytes, we consider the Channel not writable.
