Class JTLData

java.lang.Object
  extended by org.apache.jmeter.testelement.JTLData
All Implemented Interfaces:
Serializable, DataSet, Visualizer

public class JTLData
extends Object
implements Serializable, DataSet

The purpose of TableData is to contain the results of a single .jtl file. It is equivalent to what the AggregateListener table. A HashMap is used to store the data. The URL is the key and the value is SamplingStatCalculator

Constructor Detail

JTLData

public JTLData()
Method Detail

getURLs

public Set<?> getURLs()
Return a Set of the URLs

Specified by:
getURLs in interface DataSet
Returns:
set of URLs

getStats

public Set<SamplingStatCalculator> getStats()
Return a Set of the values

Specified by:
getStats in interface DataSet
Returns:
values

getStats

public List getStats(List urls)
The purpose of the method is to make it convienant to pass a list of the URLs and return a list of the SamplingStatCalculators. If no URLs match, the list is empty. TODO - this method seems to be wrong - it does not agree with the Javadoc The SamplingStatCalculators will be returned in the same sequence as the url list.

Specified by:
getStats in interface DataSet
Parameters:
urls -
Returns:
array list of non-null entries (may be empty)

setDataSource

public void setDataSource(String absolutePath)
Description copied from interface: DataSet
Depending on the implementation, the datasouce could be a file or a RDBMS. It's up to the implementing class to decide.

Specified by:
setDataSource in interface DataSet

getDataSource

public String getDataSource()
Description copied from interface: DataSet
Return the datasource. For files, it should be the absolute path. For databases, it should be the datasource name created in jmeter.

Specified by:
getDataSource in interface DataSet

getDataSourceName

public String getDataSourceName()
Description copied from interface: DataSet
In some cases, we may want to return a string that isn't the full datasource string or something different. For example, we may want to return just the filename and not the absolutePath of a JTL file.

Specified by:
getDataSourceName in interface DataSet

setStartTimestamp

public void setStartTimestamp(long stamp)
Description copied from interface: DataSet
Set the timestamp using the first result from the datasource

Specified by:
setStartTimestamp in interface DataSet

getStartTimestamp

public long getStartTimestamp()
Description copied from interface: DataSet
return the timestamp in millisecond format.

Specified by:
getStartTimestamp in interface DataSet

setEndTimestamp

public void setEndTimestamp(long stamp)
Description copied from interface: DataSet
Set the timestamp using the last result from the datasource

Specified by:
setEndTimestamp in interface DataSet

getEndTimestamp

public long getEndTimestamp()
Description copied from interface: DataSet
return the timestamp in millisecond format.

Specified by:
getEndTimestamp in interface DataSet

getDate

public Date getDate()
The date we use for the result is the start timestamp. The reasoning is that a test may run for a long time, but it is most likely scheduled to run using CRON on unix or scheduled task in windows.

Specified by:
getDate in interface DataSet
Returns:
start time

getMonthDayDate

public String getMonthDayDate()
Description copied from interface: DataSet
convienance method for getting the date in mmdd format

Specified by:
getMonthDayDate in interface DataSet

getMonthDayYearDate

public String getMonthDayYearDate()
Description copied from interface: DataSet
convienant method for getting the date in yyyymmdd format

Specified by:
getMonthDayYearDate in interface DataSet

getStatistics

public SamplingStatCalculator getStatistics(String url)
The method will SamplingStatCalculator for the given URL. If the URL doesn't exist, the method returns null.

Specified by:
getStatistics in interface DataSet
Parameters:
url -
Returns:
data for this URL

loadData

public void loadData()
The implementation loads a single .jtl file and cleans up the ResultCollector.

Specified by:
loadData in interface DataSet

add

public void add(SampleResult sample)
the implementation will set the start timestamp if the HashMap is empty. otherwise it will set the end timestamp using the end time

Specified by:
add in interface Visualizer

isStats

public boolean isStats()
By default, the method always returns true. Subclasses can over ride the implementation.

Specified by:
isStats in interface Visualizer
Returns:
true if visualiser generates statistics
