FixB is a library for Java/FIX bindings that simplifies serialization of Java objects to/from FIX protocol messages. The bindings are implemented using Java annotations.
The library is especially useful when there is a need to interchange custom non-standard FIX messages.
Features include:
- Custom FIX tags
- Supports any protocol version as long as the format is FIX
- No requirement for classes mutability, inheritance, constructor etc.
- Model classes can be as complex as needed including composition and inheritance
- Supports FIX fields, repeating groups, blocks/components
- FIX bindings for enum types (with default behaviour based on ordinal value)
- FIX bindings for JodaTime types
- Repeating groups binding directly to java collections
- Optional QuickFIX/J adapter (fixb-quickfix)
To include FixB into a maven project add the following repository in your settings.xml or pom.xml:
<repository>
<id>fixb-repo</id>
<url>http://raw.github.com/YTEQ/fixb/mvn-repo/</url>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</repository>And add the following dependency in your pom.xml (check for the latest version):
<dependency>
<groupId>org.fixb</groupId>
<artifactId>fixb</artifactId>
<version>1.0-beta</version>
</dependency>@FixMessage(type = "Q")
public class FxQuote extends BaseQuote {
public static enum Side { BUY, SELL }
@FixField(tag = 40)
private final Side side;
@FixField(tag = 12)
private final String symbol;
@FixGroup(tag = 13, componentTag = 14)
private final List<Integer> amounts;
@FixGroup(tag = 20)
private final List<Params> paramsList;
@FixBlock
private final Params params;
public FxQuote(
final String quoteId,
final Side side,
final String symbol,
final List<Integer> amounts,
final List<Params> paramsList,
final Params params) {
super(quoteId);
this.side = side;
this.symbol = symbol;
this.amounts = amounts;
this.paramsList = paramsList;
this.params = params;
}
public String getSymbol() {
return symbol;
}
public Side getSide() {
return side;
}
public List<Integer> getAmounts() {
return amounts;
}
public Params getParams() {
return params;
}
public List<Params> getParamsList() {
return paramsList;
}
}To start serializing your POJOs into FIX messages and vice versa it's enough to create an instance of a FixSerializer as below:
FixMetaDictionary fixMetaDictionary = FixMetaScanner.scanClassesIn("my.fix.classes.package");
FixSerializer<Object> fixSerializer = new NativeFixSerializer<>("FIX.5.0", fixMetaDictionary);And actually using the created FixSerializer:
FxQuote fxQuote = new FxQuote(...);
// Convert a POJO into a FIX message
String fixMessage = fixSerializer.serialize(fxQuote);
// Read a FIX string as a FxQuote instance
FxQuote fxQuote = fixSerializer.deserialize(fixMessage);
