Constructor Detail

AbstractLogReplayer

public AbstractLogReplayer(java.lang.String monitoringConfigurationFile,
                           boolean realtimeMode,
                           double realtimeAccelerationFactor,
                           boolean keepOriginalLoggingTimestamps,
                           int numRealtimeWorkerThreads,
                           long ignoreRecordsBeforeTimestamp,
                           long ignoreRecordsAfterTimestamp)
Parameters:
monitoringConfigurationFile - The name of the monitoring.properties file.
realtimeMode - Determines whether to use real time mode or not.
realtimeAccelerationFactor - Determines whether to accelerate (value > 1.0) or slow down (<1.0) the replay in realtime mode by the given factor. Choose a value of 1.0 for "real" realtime mode (i.e., no acceleration/slow down)
keepOriginalLoggingTimestamps - Determines whether the original logging timestamps will be used of whether the timestamps will be modified.
numRealtimeWorkerThreads - Determines how many realtime worker threads should be used.
ignoreRecordsBeforeTimestamp - The lower limit for the time stamps of the records.
ignoreRecordsAfterTimestamp - The upper limit for the time stamps of the records.
Method Detail

replay

public boolean replay()
Replays the monitoring log terminates after the last record was passed to the configured IMonitoringController.

Returns:
true on success; false otherwise

readerOutputPortName

protected abstract java.lang.String readerOutputPortName()
Implementing classes returns the name of the reader's output port which provides the IMonitoringRecords from the monitoring log.

Returns:
The name of the reader's output port.

createReader

protected abstract AbstractReaderPlugin createReader(IAnalysisController analysisInstance)
Implementing classes return the reader to be used for reading the monitoring log.

Parameters:
analysisInstance - The analysis controller which will be the parent of the reader.
Returns:
The reader which can be used to read the monitoring log.
