public class CurrentTimeEventGenerationFilter
extends AbstractFilterPlugin

Generates time events with a given resolution based on the timestamps of incoming IMonitoringRecords.

1. The first record received via inputTimestamp(Long) immediately leads to a new TimestampEvent with the given timestamp.
2. The timestamp of the first record is stored as firstTimestamp and future events are generated at firstTimestamp + i * timerResolution.
3. Future IMonitoringRecord may lead to future TimestampRecord as follows:
   1. A newly incoming IMonitoringRecord with logging timestamp tstamp leads to the new timer events satisfying firstTimestamp + i * timerResolution < tstamp.

It is guaranteed that the generated timestamps are in ascending order.

Constructor Summary

CurrentTimeEventGenerationFilter(Configuration configuration)
Creates an event generator which generates time events with the given resolution in nanoseconds via the output port OUTPUT_PORT_NAME_CURRENT_TIME.

Method Summary

Configuration	getCurrentConfiguration() This method should deliver a Configuration object containing the current configuration of this instance.
void	inputRecord(IMonitoringRecord record)
void	inputTimestamp(Long timestamp) Evaluates the given timestamp internal current time which may lead to newly generated events via OUTPUT_PORT_NAME_CURRENT_TIME.

Constructor Detail

CurrentTimeEventGenerationFilter

public CurrentTimeEventGenerationFilter(Configuration configuration)

Creates an event generator which generates time events with the given resolution in nanoseconds via the output port OUTPUT_PORT_NAME_CURRENT_TIME.

Parameters:

configuration - The configuration to be used for this plugin.

Method Detail

inputRecord

public void inputRecord(IMonitoringRecord record)

inputTimestamp

public void inputTimestamp(Long timestamp)

Evaluates the given timestamp internal current time which may lead to newly generated events via OUTPUT_PORT_NAME_CURRENT_TIME.

getCurrentConfiguration

public Configuration getCurrentConfiguration()

Description copied from interface: IPlugin

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.

Returns:

A completely filled configuration object.
