Namespace OnixS.Fix.Fast

Classes

Coder

DecodeResult

Result of message decoding.

DecodedValue<T>

Decoded value.

Decoder

FAST-to-FIX Decoder.

DecoderExtension

Extensions to the Decoder class.

DictionaryBuilder

Builder of FIX dictionaries on the base of FAST template.

DynamicErrorException

Dynamic error.

Instance of the class reflects a dynamic error during encoding or decoding. Such errors mostly appear when there is a wrong or damaged input data, or when the message being encoded contains inacceptable values in its fields.

DynamicErrorException.ErrorCode

Valid error codes.

D2100-D2499 This range is split by the following rules:

Subrange	Description
D2100-D2199	Recoverable or conditionally recoverable errors. See the specific error description for details.
D2200-D2299	Unrecoverable decoding errors. Such errors require at least to call the Reset() method to continue operations.
D2300-D2399	Errors in the message being encoded. Such errors can require to call the Reset() method to continue operation and definitely needs to change content of the encoded message.

D2500 and above Internal errors that should be never appeared.

Encoder

FIX-to-FAST Encoder.

FastErrorCode

Represents error code of the given exception.

FastException

Base FAST exception.

NotEnoughInputDataException

Not enough input data.

This class replaces instance of the DynamicErrorException with Code == DynamicErrorException.ErrorCode.D2100. It is introduced to support the idiomatic approach of exception analyze due to recoverable nature of this error.

In particular it allows to make dedicated catch clause for the data shortage error:

try {
    decoder.Decode( ... );
} catch(NotEnoughInputDataException) {
   // Go to obtain more data and repeat the decoding.
} catch(FastException e) {
   // Other errors, basically - unrecoverable ones.
}

StaticErrorException

Static errors.

Such errors appear during FAST template parsing and expose the fact that the FAST template composed with particular errors.

StaticErrorException.ErrorCode

Valid error codes.

Interfaces

FixMessageFactory

FIX message factory interface.
