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 TimestampRecord 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.

Since:

1.3

CONFIG_NAME

Constructor Summary

CurrentTimeEventGenerationFilter(Configuration configuration, IProjectContext projectContext)
Creates an event generator which generates time events with the given resolution in timeunits via the output port OUTPUT_PORT_NAME_CURRENT_TIME_RECORD.

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	inputRecord(IMonitoringRecord record) This method represents the input port for new records.
void	inputTimestamp(Long timestamp) Evaluates the given timestamp internal current time which may lead to newly generated events via OUTPUT_PORT_NAME_CURRENT_TIME_RECORD.

Constructor Detail

CurrentTimeEventGenerationFilter

public CurrentTimeEventGenerationFilter(Configuration configuration,
                                        IProjectContext projectContext)

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

Parameters:

configuration - The configuration to be used for this plugin.

projectContext - The project context to be used for this plugin.

Method Detail

inputRecord

public void inputRecord(IMonitoringRecord record)

This method represents the input port for new records.

Parameters:

record - The next 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_RECORD.

Parameters:

timestamp - The next timestamp.

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.
