Method Detail

fill

public void fill(double x)
          throws IllegalArgumentException

Fill the ICloud1D with a value and a corresponding weight. If either the value or the weight is NaN the entry will be recorded but it will not contribue to the statistics.

Parameters:

x - The value.

Throws:

IllegalArgumentException - If the ICloud1D is full or if the weight's value is not between 0 and 1.

fill

public void fill(double x,
                 double weight)
          throws IllegalArgumentException

Fill the ICloud1D with a value and a corresponding weight. If either the value or the weight is NaN the entry will be recorded but it will not contribue to the statistics.

Parameters:

x - The value.

weight - The corresponding weight. By default it is 1.

Throws:

IllegalArgumentException - If the ICloud1D is full or if the weight's value is not between 0 and 1.

lowerEdge

public double lowerEdge()

Get the lower edge of the ICloud1D.

Returns:

The lower edge.

upperEdge

public double upperEdge()

Get the upper edge of the ICloud1D.

Returns:

The upper edge.

value

public double value(int index)
             throws AlreadyConvertedException

Get the value corresponding to a given entry.

Parameters:

index - The entry's index.

Returns:

The value of the index-th entry.

Throws:

AlreadyConvertedException - If the ICloud1D has already been converted.

weight

public double weight(int index)
              throws AlreadyConvertedException

Get the weight corresponding to a given entry.

Parameters:

index - The entry's index.

Returns:

The weight of the index-th entry.

Throws:

AlreadyConvertedException - If the ICloud has already been converted.

mean

public double mean()

Get the mean of the ICloud1D.

Returns:

The mean.

rms

public double rms()

Get the RMS of the ICloud1D.

Returns:

The RMS.

convert

public void convert(int nBins,
                    double lowerEdge,
                    double upperEdge)
             throws AlreadyConvertedException

Convert internally the ICloud1D to an IHistogram1D with given number of bins, upper edge and lower edge.

Parameters:

nBins - The number of bins.

lowerEdge - The lower edge.

upperEdge - The upper edge.

Throws:

AlreadyConvertedException - If the ICloud1D has already been converted.

convert

public void convert(double[] binEdges)
             throws AlreadyConvertedException

Convert internally the ICloud1D to an IHistogram1D with given bin edges.

Parameters:

binEdges - The bins edges.

Throws:

AlreadyConvertedException - If the ICloud1D has already been converted.

histogram

public IHistogram1D histogram()

Get the internal IHistogram1D into which the ICloud1D was converted. If the cloud has not been converted yet, a call to this method will auto-convert it.

Returns:

The histogram.

fillHistogram

public void fillHistogram(IHistogram1D hist)
                   throws RuntimeException

Project the ICloud1D on an IHistogram1D.

Parameters:

hist - The IHistogram1D to be filled.

Throws:

RuntimeException - If the ICloud1D is already converted.

setConversionParameters

public void setConversionParameters(int bins,
                                    double lowerEdge,
                                    double upperEdge)
                             throws IllegalArgumentException

Set the parameters for the ICloud conversion to an IHistogram.

Parameters:

bins - The number of bins of the conversion IHistogram.

lowerEdge - The lower edge of the conversion IHistogram.

upperEdge - The upper edge of the conversion IHistogram.

Throws:

IllegalArgumentException
