Example 1 with FacadeSegment

use of com.amazonaws.xray.entities.FacadeSegment in project aws-xray-sdk-java by aws.

the class LambdaSegmentContext method endSubsegment.

@Override

    Entity current = getTraceEntity();
    if (current instanceof Subsegment) {
        if (logger.isDebugEnabled()) {
            logger.debug("Ending subsegment named: " + current.getName());
