Constructor Detail

CumulativeDataEvent

public CumulativeDataEvent(Object src)

Constructs a new data event given only the data event source.

CumulativeDataEvent

public CumulativeDataEvent(DataEvent source)

Constructs a new cumulative data event from a single data event.

Method Detail

setRawMinMax

public void setRawMinMax(double min,
                         double max)

Sets the sigma of the raw measurments. Normally calculated from the standard deviation of the constituing data events.

getRawMax

public double getRawMax()

Returns the maximum of the measurements or NaN if undefined.

getFormattedRawMax

public String getFormattedRawMax()

Returns the raw maximum, formatted to the raw formatter.

getRawMin

public double getRawMin()

Returns the minimum of the measurements or NaN if undefined.

getFormattedRawMin

public String getFormattedRawMin()

Returns the raw minimum, formatted to the raw formatter.

getPhysicalMax

public double getPhysicalMax()

Returns the maximum of the measurements in physically meaningful quantities or NaN if undefined.

getFormattedPhysicalMax

public String getFormattedPhysicalMax()

Returns the physical maximum, formatted to the physical formatter.

getPhysicalMin

public double getPhysicalMin()

Returns the minimum of the measurements in physically meaningful quantities or NaN if undefined.

getFormattedPhysicalMin

public String getFormattedPhysicalMin()

Returns the physical minimum, formatted to the physical formatter.

setN

public void setN(int nr)

Sets the number of measurements. If the argument is less than zero, n is set to zero, indicating invalid setting.

getN

public int getN()

Returns the number of measurements or zero if undefined.

toString

public String toString()

Adds min/max info to the string representation.

Overrides:

toString in class RawDataEvent

getDateString

protected String getDateString()

Overrides the data string. If this data event has multiple data, the number of constituing data points is shown right after the date.

Overrides:

getDateString in class RawDataEvent

getMinMaxString

protected String getMinMaxString(Double min,
                                 Double max)

Constructs a line similar to

       min: raw (phys), max: raw (phys)
       

where raw is the raw reading, while phys is the physical quantity (if available). If no min/max info is available an empty string is returned.
This method uses the standard physical conversion utility and the raw-value format.

Parameters:

min - The minimum Double.

max - The minimum Double.
