public class TraceAggregationFilter
extends AbstractFilterPlugin

This filter collects incoming traces for a specified amount of time. Any traces representing the same series of events will be used to calculate statistical informations like the average runtime of this kind of trace. Only one specimen of these traces containing this information will be forwarded from this filter. Statistical outliers regarding the runtime of the trace will be treated special and therefore send out as they are and will not be mixed with others.

Constructor Summary
TraceAggregationFilter(Configuration configuration, IProjectContext projectContext)
          Creates a new instance of this class using the given parameters.
 
Method Summary
 Configuration getCurrentConfiguration()
          This method should deliver a Configuration object containing the current configuration of this instance. In other words: The constructor should be able to use the given object to initialize a new instance of this class with the same intern properties.
 void newEvent(Long timestamp)
          This method is the input port for the timeout.
 void newEvent(TraceEventRecords traceEventRecords)
          This method is the input port for incoming traces.
 void terminate(boolean error)
          Initiates a termination of the plugin. This method is only used by the framework and should not be called manually. Use the method AnalysisController.terminate(boolean) instead. After receiving this notification, the plugin should terminate any running methods, e.g., read for readers.

Constructor Detail

TraceAggregationFilter

public TraceAggregationFilter(Configuration configuration,
                              IProjectContext projectContext)
Creates a new instance of this class using the given parameters.

Parameters:
configuration - The configuration for this component.
projectContext - The project context for this component.
Method Detail

newEvent

public void newEvent(Long timestamp)
This method is the input port for the timeout.

Parameters:
timestamp - The timestamp

newEvent

public void newEvent(TraceEventRecords traceEventRecords)
This method is the input port for incoming traces.

Parameters:
traceEventRecords - incoming TraceEventRecords

terminate

public void terminate(boolean error)
Initiates a termination of the plugin. This method is only used by the framework and should not be called manually. Use the method AnalysisController.terminate(boolean) instead. After receiving this notification, the plugin should terminate any running methods, e.g., read for readers.

Specified by:
terminate in interface IPlugin
Overrides:
terminate in class AbstractFilterPlugin
Parameters:
error - Determines whether the plugin is terminated due to an error or not.

getCurrentConfiguration

public Configuration getCurrentConfiguration()
This method should deliver a Configuration object containing the current configuration of this instance. In other words: The constructor should be able to use the given object to initialize a new instance of this class with the same intern properties.

Specified by:
getCurrentConfiguration in interface IAnalysisComponent
Specified by:
getCurrentConfiguration in interface IPlugin
Specified by:
getCurrentConfiguration in class AbstractAnalysisComponent
Returns:
A completely filled configuration object.
