th2-codec-fix-ng 0.1.5

This codec can be used in dirty mode for decoding and encoding messages via the FIX protocol.

Configuration

Configuration parameters

Configuration example.

beginString: FIXT.1.1
dictionary: "${dictionary_link:fix50-generic}"
charset: US-ASCII
decodeDelimiter: "\u0001"
dirtyMode: false
decodeValuesToStrings: true
decodeComponentsToNestedMaps: true

beginString

default value: FIXT.1.1. Value to put into the BeginString field (tag: 8) when encoding messages.

dictionary

required value. XML file containing the FIX dictionary.

charset

default value: US-ASCII. Charset for reading and writing FIX fields.

decodeDelimiter

default value: "\u0001". Delimiter character from US-ASCII charset.

dirtyMode

default value: false. If true, processes all messages in dirty mode (generates warnings on invalid messages and continues processing). If false, only messages that contain the encode-mode: dirty property will be processed in dirty mode.

decodeValuesToStrings

default value: true. If true, decodes all values to strings instead of typed values.

decodeComponentsToNestedMaps

default value: true. If true, decodes components to nested maps instead of unwrap component's map to message's main map.
