  +--elge.storage.file.DataRecorder

All Implemented Interfaces:

DataStorage

public class DataRecorder

extends Object

implements DataStorage

DataRecorder is a simple easy format data recorder. It uses very simple format for writing. Especialy for each element there is a seperate file. In each file there is a tick in every new line, there is a tick count and a value that is stored separated by ":" The format is compresed, so only changes are writen, and last tick - is writen.

getXYTickValueDataset

public com.jrefinery.data.XYDataset getXYTickValueDataset(String property,
                                                          int window)

Creates dataset that uses data stored for the "property", actualy, the X is tick count, and Y is the data...

Specified by:

getXYTickValueDataset in interface DataStorage

Parameters:

property - property name

window - the tick step size

Toto spravi viac series v tom grafe...

Specified by:

getXYTickValueDataset in interface DataStorage

Parameters:

property - the list of properties

Returns:

the dataset

getXYTickValueDataset

public com.jrefinery.data.XYDataset getXYTickValueDataset(List property)

Description copied from interface: DataStorage

Like above

Specified by:

getXYTickValueDataset in interface DataStorage

Parameters:

property - the properties

Returns:

dataset for graph

getXYTickValueDataset

public com.jrefinery.data.XYDataset getXYTickValueDataset(List property,
                                                          int window)

Description copied from interface: DataStorage

like above

Specified by:

getXYTickValueDataset in interface DataStorage

Parameters:

property - propeties

window - the tick step size

Returns:

the dataset for graph

record

public void record(Vector monitors)
            throws IOException

Stores the data from monitors.

Specified by:

record in interface DataStorage

Parameters:

monitors - The vector of monitors.

Throws:

IOException - if some io problem occures.

close

public void close()

Makes flush and save the data. This should be called befare

Specified by:

close in interface DataStorage

destroy

public void destroy()

lastTick

public Integer lastTick()

Description copied from interface: DataStorage

The lastTick that was recorder by this storage

Specified by:

lastTick in interface DataStorage

Returns:

the last tick value.

getDataReader

public DataReader getDataReader(String property)

Returns:

a DataReader, which reads the stored data...

getLastTickCategoryDataset

public com.jrefinery.data.CategoryDataset getLastTickCategoryDataset(List property)

Description copied from interface: DataStorage

An category dataset. Unlike XYDataset, this category dataset shows only last values of the tick.

Specified by:

getLastTickCategoryDataset in interface DataStorage

Parameters:

getLastTickPieDataset

public com.jrefinery.data.PieDataset getLastTickPieDataset(List property)

Description copied from interface: DataStorage

Pie dataset for the pie graph. Also a sipmle category dataset.

Specified by:

getLastTickPieDataset in interface DataStorage

Parameters:

property - the property list

getRun

public DataStorage getRun(int index)

Description copied from interface: DataStorage

Returns a DataStorage for older simulation data.

Specified by:

getRun in interface DataStorage

Parameters:

index - index of older simulation

getRunNames

public List getRunNames()

Every storage is responsible for the runs, that user makes. So one simulation coresponds to one data storage and one run. This method returns the run names user can display. To get the specific simulation data, use the getRun method.

Specified by:

getRunNames in interface DataStorage

Returns:

List of available data of older simulations

See Also:

getRun(int)

                       String property)

Description copied from interface: DataStorage

retruns a value for tick and property.

Specified by:

getValue in interface DataStorage

Parameters:

tick - the tick

property - property name
