Interface IFixMessageFactory
FixMessageFactory interface defines object capable to create session level messages. User could extend existing standard MessageFactories or even write his own custom message factory
Namespace: FixAntenna.FixEngine
Assembly: FixAntenna.Core.dll
Syntax
public interface IFixMessageFactoryProperties
MinSeqNumFieldsLength
Minimal length for the SeqNum fields. The SeqNum fields are: BeginSeqNo(7), EndSeqNo(16), MsgSeqNum(34), NewSeqNo(36), RefSeqNum(45), LastMsgSeqNumProcessed(369), HopRefID(630), NextExpectedMsgSeqNum(789)
Declaration
int MinSeqNumFieldsLength { get; }Property Value
| Type | Description |
|---|---|
| System.Int32 |
Remarks
As far as HopRefID field doesn't processed directly by FA .NET Core,
it is up to user to format this field with leading zeroes if required.
The same for any SeqNum field processed by the user's logic:
it is up to user to keep required padding using
