Detailed Description

The NumericRange class describes a range of numbers between a minimum and maximum combined with a resolution.

Constructor & Destructor Documentation

NumericRange::NumericRange	(	double	mi,
		double	ma,
		double	resolution = 0
	)

NumericRange basic constructor for the range with a minimum and a maximum and a resolution.

*If the resolution is 0, the range has same resolution a double. A step size of 0 will make the range iterator invalid. This prefectly legal, it only makes the iterator not usable. *A resolution of an integer will make the range an integer range

Parameters

mi	minimum of the range
ma	maximum of the range
step	resolution of the range.

NumericRange::NumericRange

(

const NumericRange &

vr

)

NumericRange copy constructor.

Parameters

vr	other value range

Member Function Documentation

Range * NumericRange::clone ( ) const

virtual

copies the range to a new instance. This pointer has to be deleted by the caller

Returns

the new Range

Implements Ilwis::Range.

Reimplemented in Ilwis::TimeInterval.

IlwisTypes NumericRange::determineType ( ) const

virtual

determineType determines the minimal range needed type for this range.

*For example a range of numbers can be in the 32 bits range while the range contains only the numbers between 0-255, so the minimal range would be itUINT8

Returns

an ilwistype

Reimplemented from Ilwis::Range.

bool NumericRange::isValid ( ) const

virtual

determines the validity of a range. This method must be implemented by each deravative

Returns

true for a valid range

Implements Ilwis::Range.

Reimplemented in Ilwis::TimeInterval.

QString NumericRange::toString ( ) const

virtual

translates the string into a string representation. As each type of range has a different string representation this method has to be reimplemented by each derivative

Returns

a string

Implements Ilwis::Range.
