public class DisplayRealType
extends RealType

DisplayRealType is the class for display real scalar types. ScalarMaps map ScalarTypes to DisplayRealType. A fixed set is defined by the system, users may add others.

DisplayRealType

public DisplayRealType(String name,
                       boolean single,
                       double low,
                       double hi,

                       Unit unit)
                throws VisADException

construct a DisplayRealType

Parameters:

name - String name for this DisplayRealType

single - if true, this may occur at most once at a terminal node in the ShadowType tree; see Appendix A of the Developer's Guide

low - start of range of values for scaling

hi - end of range of values for scaling

def - default value

unit - Unit for this DisplayRealType

Throws:

VisADException - a VisAD error occurred

                       double def,
                       Unit unit)
                throws VisADException

construct a DisplayRealType whose values are not scaled

Parameters:

name - String name for this DisplayRealType

single - if true, this may occur at most once at a terminal node in the ShadowType tree; see Appendix A of the Developer's Guide

def - default value

unit - Unit for this DisplayRealType

Throws:

VisADException - a VisAD error occurred

Method Detail

getTuple

public DisplayTupleType getTuple()

Returns:

the unique DisplayTupleType that this DisplayRealType is a component of, or return null if it is not a component of any DisplayTupleType

getTupleIndex

public int getTupleIndex()

Returns:

index of this as component of a DisplayTupleType (-1 if it isn't a component of any DisplayTupleType)

setTuple

public void setTuple(DisplayTupleType t,
                     int i,
                     boolean c)
              throws VisADException

Sets the DisplayTupleType to which this DisplayRealType will belong.

Parameters:

t - The DisplayTupleType of which this DisplayRealType will be a component.

i - The 0-based index for this as a component of t.

c - Flag indicating whether t has a CoordinateSystem whose toReference() is periodic in this with period 2*pi (or equivalent according to unit).

Throws:

VisADException - a VisAD error occurred.

isSingle

public boolean isSingle()

Returns:

flag indicating whether this is 'single'

getDefaultValue

public double getDefaultValue()

Returns:

default value for this DisplayRealType

getRange

public boolean getRange(double[] range_values)

get the range of values is defined for this

Parameters:

range_values - double[2] array used to return low and hi values of the range (if this DisplayRealType has a range)

Returns:

flag indicating whether this has a range (i.e., is scaled)

getText

public boolean getText()

Returns:

flag indicating whether this DisplayRealType is really a text type

getCircular

public boolean getCircular()

Returns:

flag indicating whether this has a DisplayTupleType, which has a CoordinateSystem whose toReference() is periodic in this with period 2*pi (or equivalent according to unit)
