Version 2.3.0

This version wraps the new functionality in version 1.0.27 of the native libdmf library. The following members have been added to the MarketDataFeed class and the IMarketDataFeed interface:

• 5327a64 An IntPtr Extract(out ushort mref, out ulong insref, out uint len) method that can be used to extract an unmanaged pointer to the current message from the feed handle
• 5b75d1e An int Inject(IntPtr ptr, uint len) method that injects a previously extracted message
• 5b75d1e Another int Inject(ReadOnlySpan<byte> data) overload to inject the byte data of a previously extracted message into the handle
• 14a22c8 A read-only ReadBufferSize property that gets the number of bytes waiting to be processed in the internal read buffer after a call to the Consume method
• 94f6522 A read-write ReadBufferMaxSize property that gets and sets the current size of the internal read buffer

Other changes in this release include this:

• 5ee24f5 The following ReadOnlySpan<byte> method overloads of the Message class have been added to the IMessage interface:

  • bool AddNumeric(uint tag, ReadOnlySpan<byte> value);
  • bool AddNumeric(Field tag, ReadOnlySpan<byte> value);
  • bool AddString(uint tag, ReadOnlySpan<byte> value);
  • bool AddString(uint tag, ReadOnlySpan<byte> value, int length);
  • bool AddString(Field tag, ReadOnlySpan<byte> value);
  • bool AddString(Field tag, ReadOnlySpan<byte> value, int length);
  • bool AddDate(uint tag, ReadOnlySpan<byte> value);
  • bool AddDate(Field tag, ReadOnlySpan<byte> value);
  • bool AddTime(uint tag, ReadOnlySpan<byte> value);
  • bool AddTime(Field tag, ReadOnlySpan<byte> value);
  • bool AddList(uint tag, ReadOnlySpan<byte> value);
  • bool AddList(Field tag, ReadOnlySpan<byte> value);

• a959bd2 The following enumerations have been marked with the [ObsoleteAttribute] and will probably be remove in a future version:

  • CompressionLevel
  • CorporateAction
  • Field
  • MessageClasses
  • MessageReference
  • RequestClass
  • RequestType
  • TradeCodes

  Field has been replaced by a static Fields class that contains constants for all fields.
  Similarly MessageReference has been replaced by a static MessageReferences class that contains constants for all message references, RequestClass has been replaced by a RequestClasses class with constants for all request classes and RequestType has been replaced by a RequestTypes class that contains the constants for all request types.

• b758a9c MDF_F_EVENTSTATUS, MDF_F_SMA20, MDF_F_SMA50, MDF_F_SMA200, MDF_F_RSI14,
  MDF_F_MACD, MDF_F_TRADESTATEACTIONS, MDF_F_SHARECLASS have been added to the deprecated Field enumeration and as constants in the new Fields class

• ffec795 The finalizer of the Message class no longer throws a NullReferenceException when you pass an invalid native library path to the constructor overload that accepts a string
