public SpreadSheetRowUtils()

Method Detail

getComparator

public static SpreadSheetRowPointComparator getComparator()

Returns the comparator used for finding X values.

Returns:

the comparator

findX

public static int findX(List<SpreadSheetRowPoint> points,
                        SpreadSheetRowPoint p)

Returns the index in m_Points of the given sequence point.

Parameters:

points - the data to process

p - the point to get the index for

Returns:

the index

findX

public static int findX(List<SpreadSheetRowPoint> points,
                        int x)

Returns the index in m_Points of the given x value.

Parameters:

points - the data to process

x - the x value to get the index for

Returns:

the index

findClosestX

public static int findClosestX(List<SpreadSheetRowPoint> points,
                               int x)

Returns the index in m_Points closest to the given x value.

Parameters:

points - the data to process

x - the x value to get the closest index for

Returns:

the index

findEnclosingXs

public static int[] findEnclosingXs(List<SpreadSheetRowPoint> points,
                                    int x)

Returns the indices of points in m_Points that enclose the given x value. If the given x value happens to be an exact point, then this points will be stored at index 0. If no index could be determined, then -1 will be stored.

Parameters:

points - the data to process

x - the x value to get the enclosing indices for

Returns:

the indices

toDoubleArray

public static double[] toDoubleArray(SpreadSheetRow r)

Returns the points as double array.

Parameters:

r - the row to turn into a double array

Returns:

the points as double array

toDoubleArray

public static double[] toDoubleArray(List<SpreadSheetRowPoint> data)

Returns the points as double array.

Parameters:

data - the row points to turn into a double array

Returns:

the points as double array
