CompositeTracer class

Aggregates all tracers from component references under a single component.

It allows to record traces and conveniently send them to multiple destinations.

References

• *:tracer:*:*:1.0 (optional) ITracer components to pass operation traces

See ITracer

Example

class MyComponent implements IReferenceable { var _tracer = CompositeTracer();

void setReferences(IReferences references) {
    _tracer.setReferences(references);
    ...
}

void myMethod(String correlatonId) {
    var timing = _tracer.beginTrace(correlationId, "mycomponent", "mymethod");
    try {
        ...
        timing.endTrace();
    } catch (err) {
        timing.endFailure(err);
    }
}

}
