[Openfastdotnet-users] 每个field的内容长度

[<260...@qq...>]

您好，
在使用openfast解析传递过来的stream时，有个地方一直不明白,UnsignedInteger.cs中的这个方法
  public override ScalarValue Decode(Stream inStream)
        {
            long value = 0;
            uint byt;
            try
            {
                do
                {
                    byt = (uint) inStream.ReadByte();
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; value = (value << 7) | (byt &amp; 0x7f); ----此处就代表单元格内容长度么，即由多少bit组成的，请问为什么要这么写，看不明白...
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } while ((byt &amp; StopBit) == 0);
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; catch (IOException e)
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; throw new RuntimeException(e);
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return CreateValue(value);
&nbsp; &nbsp; &nbsp; &nbsp; }

Re: [Openfastdotnet-users] MulticastInputStream and ByteBuffer

[shariq m. <sha...@gm...>]

Yes, we usually convert it from java version but now we are working on
optimization so it is changing now. their are a few areas which need
attention to optimize the context object.

About multicast class, that is not functional but this is something which
can be implemented without need of too much coding but when it was ported,
those classes were their, in actual; implementations have variations in
different scenarios in contrast to java version. Some feeds skip 5 bytes
as preamble data and some dont do that. Anyways we would add a few exchange
specific samples this week which will clarify the implementation.

[Openfastdotnet-users] MulticastInputStream and ByteBuffer

[Henry C. <hen...@gm...>]

Hi,

It looks like that these two classes are half implemented only. What
is the approach that you guys usually follow on those situations? Just
port from java source?

Cheers,

[Openfastdotnet-users] Re: Connect to exchange example

[shariq m. <sha...@gm...>]

Hi,

Yeah currently no examples are their, but i would look into BATS
specification. They are decode able through
FIXProtocol reference implementations as well. I will work on it and let you
know. I dont have BATS data currently when i will have access to it i'll
publish the samples.

Sorry for a delayed response as i was occupied in some regular work.

[Openfastdotnet-users] Connect to exchange example

[anonymous g. <ano...@gm...>]

Hi OpenFAST .NET team,

You don't happen to have an example of how to connect and use your .NET
FastFIX library when retrieving quotes from oh, say, BATS do you?

Thanks for any help,
AM
