Constructor Detail

List1DDoubleSet

public List1DDoubleSet(double[] d,
                       MathType type,
                       CoordinateSystem coord_sys,
                       Unit[] units)
                throws VisADException

Constructs with a non-default CoordinateSystem.

Parameters:

d - The data samples. Must not be null.

type - The type of the set.

coord_sys - The coordinate system transformation. May be null.

units - The units of the values. May be null.

Throws:

VisADException - Couldn't create set.

Method Detail

isMissing

public boolean isMissing()

Returns:

flag indicating whether this Data has a missing value

indexToValue

public float[][] indexToValue(int[] indices)
                       throws VisADException

Converts an array of 1-D indices to an array of values in R^1. Note that a returned values may be Double.NaN due to double-to-float conversion.

Specified by:

indexToValue in interface SetIface

Specified by:

indexToValue in class Set

Parameters:

indices - The indices of the values to be returned.

Returns:

The values associated with the given indices. A Float.NaN will be returned for an out-of-range index or a double value that cannot be converted to a float.

Throws:

VisADException - a VisAD error occurred

indexToDouble

public double[][] indexToDouble(int[] indices)
                         throws VisADException

Converts an array of 1-D indices to an array of values in R^1.

Specified by:

indexToDouble in interface SetIface

Overrides:

indexToDouble in class Set

Parameters:

indices - The indices of the values to be returned.

Returns:

The values associated with the given indices. A Double.NaN will be returned for an out-of- range index.

Throws:

VisADException - if a VisAD failure occurs.

valueToIndex

public int[] valueToIndex(float[][] values)
                   throws VisADException

Converts an array of values in R^1 to an array of 1-D indices. This method is unimplemented because this class doesn't support interpolation.

Specified by:

valueToIndex in interface SetIface

Specified by:

valueToIndex in class Set

Parameters:

values - The values to have their indicies returned.

Returns:

array of integer indices

Throws:

UnimplementedException - Always.

VisADException - a VisAD error occurred

valueToInterp

public void valueToInterp(float[][] value,
                          int[][] indices,
                          float[][] weights)
                   throws VisADException

for each of an array of values in R^DomainDimension, compute an array of 1-D indices and an array of weights, to be used for interpolation; indices[i] and weights[i] are null if i-th value is outside grid (i.e., if no interpolation is possible)

Specified by:

valueToInterp in interface SimpleSetIface

Specified by:

valueToInterp in class SimpleSet

Parameters:

value - An array of points. value[i][j] is the i-th coordinate of the j-th points.

indices - Indices of the neighboring samples in the set. If the j-th points lies within the set, then returned element [i][j] is the index of the i-th neighboring sample in the set; otherwise, returned array [j] is null.

weights - Weights for interpolating the neighboring samples in the set. If the j-th points lies within the set, then returned element [i][j] is the weight of the i-th neighboring sample in the set; otherwise, returned array [j] is null.

Throws:

VisADException - VisAD failure.

equals

public boolean equals(java.lang.Object set)

Description copied from class: Set

test for equality

Specified by:

equals in interface SetIface

Specified by:

equals in class Set

hashCode

public int hashCode()

Returns the hash code of this instance.

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code of this instance.

cloneButType

public java.lang.Object cloneButType(MathType type)
                              throws VisADException

Description copied from class: Set

copy this Set, but give it a new MathType; this is safe, since constructor checks consistency of DomainCoordinateSystem and SetUnits with Type

Specified by:

cloneButType in interface SetIface

Specified by:

cloneButType in class Set

Parameters:

type - The MathType for the clone.

Returns:

A clone of this set with the new MathType.

Throws:

VisADException - VisAD failure.

longString

public java.lang.String longString(java.lang.String pre)

Returns a pretty string about this instance.

Specified by:

longString in interface Data

Overrides:

longString in class Set

Parameters:

pre - String added to start of each line

Returns:

A pretty string about this instance.
