Method Detail

start

public ASimpleMeasurement start(String identifier,
                                boolean isSerial)

Specified by:

start in interface AMeasurementHierarchy

finish

public void finish(com.nsysmon.measure.ASimpleSerialMeasurementImpl measurement)

Specified by:

finish in interface AMeasurementHierarchy

finish

public void finish(com.nsysmon.measure.ASimpleParallelMeasurementImpl m)

Specified by:

finish in interface AMeasurementHierarchy

startCollectingMeasurement

public ACollectingMeasurement startCollectingMeasurement(String identifier,
                                                         boolean isSerial)

Specified by:

startCollectingMeasurement in interface AMeasurementHierarchy

finish

public void finish(ACollectingMeasurement m)

Specified by:

finish in interface AMeasurementHierarchy

onStartFlow

public void onStartFlow(ACorrelationId correlationId)

notifies that this measurements contains the start of a new 'flow', i.e. it is the first point in a (potential) chain of measurements that are somehow correlated.

Specified by:

onStartFlow in interface AMeasurementHierarchy

onJoinFlow

public void onJoinFlow(ACorrelationId correlationId)

notifies that this measurements is part of an existing 'flow', i.e. there is another measurement that 'started' a set of measurements that are somehow correlated.

Specified by:

onJoinFlow in interface AMeasurementHierarchy
