Constructor Detail

Gridded1DSet

public Gridded1DSet(MathType type,
                    float[][] samples,
                    int lengthX)
             throws VisADException

Constructs a 1-D sorted sequence with no regular interval. The coordinate system and units are the default from the set type. The error estimate is null.

Parameters:

type - The type of the set. Must be a RealType or a single-component RealTupleType or SetType.

samples - The values in the set. samples[0][i] is the value of the ith sample point. Must be sorted (either increasing or decreasing). May be null.

lengthX - The number of samples.

Gridded1DSet

public Gridded1DSet(MathType type,
                    float[][] samples,
                    int lengthX,
                    CoordinateSystem coord_sys,
                    Unit[] units,
                    ErrorEstimate[] errors)
             throws VisADException

Constructs a 1-D sorted sequence with no regular interval.

Parameters:

type - The type of the set. Must be a RealType or a single-component RealTupleType or SetType.

samples - The values in the set. samples[0][i] is the value of the ith sample point. Must be sorted (either increasing or decreasing). May be null.

lengthX - The number of samples.

coord_sys - The coordinate system for this, particular, set. Must be compatible with the default coordinate system. May be null.

units - The units for the tuple components. Only units[0] is meaningfull. Must be compatible with the default unit. May be null.

errors - The error estimates of the tuple components. Only errors[0] is meaningful. May be null.

Gridded1DSet

             throws VisADException

Constructs a 1-D sorted sequence with no regular interval.

Parameters:

type - The type of the set. Must be a RealType or a single-component RealTupleType or SetType.

samples - The values in the set. samples[0][i] is the value of the ith sample point. Must be sorted (either increasing or decreasing). May be null.

copy - Whether or not to copy the values array.

Method Detail

create

public static Gridded1DSet create(MathType type,
                                  float[] samples,
                                  CoordinateSystem coordSys,
                                  Unit unit,
                                  ErrorEstimate error)
                           throws VisADException

Returns an instance of this class. This method uses a weak cache of previously-created instances to reduce memory usage.

Parameters:

type - The type of the set. Must be a RealType or a single-component RealTupleType or SetType.

samples - The values in the set. samples[i] is the value of the ith sample point. Must be sorted (either increasing or decreasing). May be null. The array is not copied, so either don't modify it or clone it first.

coord_sys - The coordinate system for this, particular, set. Must be compatible with the default coordinate system. May be null.

unit - The unit for the samples. Must be compatible with the default unit. May be null.

error - The error estimate of the samples. May be null.

valueToIndex

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

Convert an array of values in R^DomainDimension to an array of 1-D indices. This Gridded1DSet must have at least two points in the set.

Parameters:

value - An array of coordinates. value[i][j] contains the ith component of the jth point.

Returns:

Indices of nearest points. RETURN_VALUE[i] will contain the index of the point in the set closest to value[][i] or -1 if value[][i] lies outside the set.
