Demultiplexing using Dynamic Code Generation A new packet-filter system, DPF (Dynamic Packet Filters), that provides both the traditional flexibility of packet filters and the speed of hand- crafted demultiplexing demultiplexing routines. DPF filters run 10–50 times faster than the fastest packet filters reported in the literature. DPF’s performance is either equivalent to or, when it can exploit runtime information declarative packet-filter language that is aggressively optimized using dynamic code generation. — 1994 (read)DPF Fast, Flexible Message Demultiplexing using Dynamic Code Generation A new packet-filter

TDataPacketFormat Value Explanation dfAny Data packets can be in any supported format (detected by the packet reader) dfBinary Data packets are in binary format dfDefault Use the default XML format. Same as TBufDataset TDatapacketReaderClass = Class of TDatapacketReader Class type used to create data packet readers for TBufDataset TDBCompareStruct = Array of TDBCompareRec TDBCompareStruct is an array enumeration. TRow- State is used to indicate the state for records loaded and saved using the data packet handler in TBufDataset. TRowStateValue = (rsvOriginal,rsvDeleted,rsvInserted,rsvUpdated, rsvDetailUpdates)

If allowHalfOpen is true, then the socket won't automatically send FIN packet when the other end of the socket sends a FIN packet. The socket becomes non-readable, but still writable. You should call fileDescriptor，并在另一端监听'fd'事件。 socket.end([data], [encoding]) Half-closes the socket. I.E., it sends a FIN packet. It is possible the server will still send some data. 发送一个 FIN 数据包，关闭 socket 半连接。服务器仍可能发送一些数据。 sent on an idle socket. Set initialDelay (in milliseconds) to set the delay between the last data packet received and the first keepalive probe. Setting 0 for initialDelay will leave the value unchanged
