public class FloatSet
FloatSet represents the finite (but large) set of samples of R^dimension made by vectors of IEEE single precision floating point numbers. FloatSet objects are immutable.
FloatSet cannot be used for the domain sampling of a Field.

Constructor Summary | |
---|---|
FloatSet(MathType type)
construct a FloatSet object with null CoordinateSystem and Units |
|
FloatSet(MathType type,
CoordinateSystem coord_sys,
Unit[] units)
the set of values representable by N floats; type must be a RealType, a RealTupleType or a SetType; coordinate_system and units must be compatible with defaults for type, or may be null; a FloatSet may not be used as a Field domain |

Object |
clone()
Clones this instance. |
Object |
cloneButType(MathType type)
copy this Set, but give it a new MathType; this is safe, since constructor checks consistency of DomainCoordinateSystem and SetUnits with Type |
boolean |
equals(Object set)
test for equality |
int |
getLength()
get the number of samples |
float[][] |
indexToValue(int[] index)
return Set values corresponding to Set indices |
boolean |
isMissing()

String |
longString(String pre)

int[] |
valueToIndex(float[][] value)
return Set indices of Set values closest to value elements (return -1 for any value outside Set range) |
void |
valueToInterp(float[][] value,
int[][] indices,
float[][] weights)
convert an array of values to arrays of indices and weights for those indices, appropriate for interpolation; the values array is organized as float[domain_dimension][number_of_values]; indices and weights must be passed in as int[number_of_values][] and float[number_of_values][]; on return, quantity( values[.] |
