Example 1 with SupportedFeatureKey

use of org.apache.kafka.common.message.ApiVersionsResponseData.SupportedFeatureKey in project kafka by apache.

            }
            return new FeatureMetadata(finalizedFeatures, finalizedFeaturesEpoch, supportedFeatures);
        }

        @Override

            return new ApiVersionsRequest.Builder();
        }

    runnable.call(call, now);
    return new DescribeFeaturesResult(future);
}

Example 2 with SupportedFeatureKey

use of org.apache.kafka.common.message.ApiVersionsResponseData.SupportedFeatureKey in project kafka by apache.

the class ApiVersionsResponse method createSupportedFeatureKeys.

private static SupportedFeatureKeyCollection createSupportedFeatureKeys(Features<SupportedVersionRange> latestSupportedFeatures) {
    SupportedFeatureKeyCollection converted = new SupportedFeatureKeyCollection();
    for (Map.Entry<String, SupportedVersionRange> feature : latestSupportedFeatures.features().entrySet()) {
        final SupportedFeatureKey key = new SupportedFeatureKey();
        final SupportedVersionRange versionRange = feature.getValue();
        key.setName(feature.getKey());
        key.setMinVersion(versionRange.min());
        key.setMaxVersion(versionRange.max());
        converted.add(key);
    }
    return converted;
