Manually setting feature control points

Aperture Java SDK core library can be used to manually set feature Control Points within a Java service.

To do so, first create an instance of ApertureSDK:

    String agentHost = "localhost";
    int agentPort = 8089;

    ApertureSDK apertureSDK;
    try {
        apertureSDK = ApertureSDK.builder()
                .setHost(agentHost)
                .setPort(agentPort)
                .setDuration(Duration.ofMillis(1000))
                .build();
    } catch (ApertureSDKException e) {
        e.printStackTrace();
        return;
    }

The created instance can then be used to start a flow:

    Map<String, String> labels = new HashMap<>();

    // business logic produces labels
    labels.put("key", "value");

    Flow flow = apertureSDK.startFlow("featureName", labels);
    if (flow.accepted()) {
        // do actual work
        flow.end(FlowStatus.OK);
    } else {
        // handle flow rejection by Aperture Agent
        flow.end(FlowStatus.Error);
    }
