public class EnumData

extends FloatData

An EnumData object represents enumerated data value. EnumData supports integer and fractional number values. In particular, EnumData inherits FloatData instead of for example IntegerData to allow manipulation and interpolation of fraction values. Fraction values are mapped to integer enumerated values by first trucating the fraction values to corresponding integer values, and then mapping the results to enumerated values.

JDK1.1

Constructor Detail

EnumData

public EnumData(EnumData ed)

Shallow copy constructor.

EnumData

public EnumData(EnumData ed,
                boolean deep)

Deep or shallow copy constructor. If it is shallow, then the new object shares an underlying type with the original object. If it is deep, then the type is dupped.

Parameters:

ed - source data (may be null)

deep - determines if the copying is deep or shallow

EnumData

public EnumData(EnumType type)

Creates a new enumerated data object with the given enumeration type and default value (0).

Parameters:

type - enumerated type that provides the mapping between enumeration indexes and values.

EnumData

public EnumData(EnumType type,
                java.lang.Number value)

Creates a new enumerated data object with the given enumeration type and value.

Parameters:

type - enumerated type that provides mapping between enumeration indexes and values.

EnumData

public EnumData(EnumType type,
                float value)

Creates a new enumerated data object with the given enumeration type and value.

Parameters:

type - enumerated type that provides mapping between enumeration indexes and values.

EnumData

public EnumData(EnumType type,
                int value)

Creates a new enumerated data object with the given enumeration type and value.

Parameters:

type - enumerated type that provides mapping between enumeration indexes and values.

EnumData

public EnumData(EnumType type,
                java.lang.String stringValue,
                java.text.ParsePosition status)
         throws InvalidDataException

Creates a enum data value from a string value.

Parameters:

stringValue - string value to be parsed

status - parse status (may be null)

Throws:

InvalidDataException - if string value could not be parser
