Method Details

init

public void init(ComputationContext context)

Description copied from interface: Computation

Called when the framework has registered the computation successfully. Gives users a first opportunity to schedule timer callbacks and produce records. This method can be called multiple times.

Specified by:

init in interface Computation

Overrides:

init in class LatencyTrackerComputation

Parameters:

context - The computation context object provided by the system.

processLatencies

protected void processLatencies(ComputationContext context,
 LogPartitionGroup logGroup,
 List<Latency> latencies)

Overrides:

processLatencies in class LatencyTrackerComputation

publishMetrics

protected void publishMetrics(Latency latency,
 String prefix)

destroy

public void destroy()

Description copied from interface: Computation

Called when the framework is ready to shutdown the computation. Gives users a chance to perform some cleanup before the process is killed.

Specified by:

destroy in interface Computation

Overrides:

destroy in class LatencyTrackerComputation
