the class JaegerSpanHandler method handleStateStackClearance.

@Override

Example 3 with ContinuationStateSequenceInfo

use of org.apache.synapse.aspects.flow.statistics.opentracing.models.ContinuationStateSequenceInfo in project wso2-synapse by wso2.

the class JaegerSpanHandler method bufferSequenceContinuationState.

/**
 * Buffers the given statistic data unit which is reported by an open event,
 * until an appropriate continuation stack event is reported.
 * A continuation event does not have the information about statistic data units to start and stop spans,
 * and that information can only be obtained from this buffered open event.
 * @param statisticDataUnit Statistic data unit object.
