Detailed Description

The Range class base interface for all objects that need to define a range of values.

*Examples of dervatives of this class are numerical ranges, thematical collections, time intervals. The class itself has not that usefull an interface but pointers to this class can be used as a *a general container for more specialized ranges .

Member Function Documentation

virtual Range* Ilwis::Range::clone ( ) const

pure virtual

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

Returns

the new Range

Implemented in Ilwis::TimeInterval, Ilwis::NamedIdentifierRange, Ilwis::Box< T >, Ilwis::Box< Ilwis::Pixel >, Ilwis::Box< Ilwis::Coordinate >, Ilwis::NumericItemRange, Ilwis::IndexedIdentifierRange, Ilwis::ContinousColorRange, and Ilwis::NumericRange.

virtual IlwisTypes Ilwis::Range::determineType ( ) const

inlinevirtual

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 in Ilwis::ValueRange< T >, and Ilwis::NumericRange.

virtual bool Ilwis::Range::isValid ( ) const

pure virtual

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

Returns

true for a valid range

Implemented in Ilwis::TimeInterval, Ilwis::NamedIdentifierRange, Ilwis::Box< T >, Ilwis::Box< Ilwis::Pixel >, Ilwis::Box< Ilwis::Coordinate >, Ilwis::ItemRange, Ilwis::ColorPalette, Ilwis::IndexedIdentifierRange, Ilwis::NumericItemRange, Ilwis::ContinousColorRange, Ilwis::NumericRange, and Ilwis::ValueRange< T >.

virtual QString Ilwis::Range::toString ( ) const

pure 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

Implemented in Ilwis::Box< T >, Ilwis::Box< Ilwis::Pixel >, Ilwis::Box< Ilwis::Coordinate >, Ilwis::NamedIdentifierRange, Ilwis::IndexedIdentifierRange, Ilwis::ValueRange< T >, Ilwis::NumericRange, Ilwis::NumericItemRange, and Ilwis::ContinousColorRange.

IlwisTypes Range::valueType ( ) const

virtual

valueType returns the type of values contained in the range

Returns

an ilwistype

Reimplemented in Ilwis::Box< T >, Ilwis::Box< Ilwis::Pixel >, Ilwis::Box< Ilwis::Coordinate >, Ilwis::ColorPalette, and Ilwis::ContinousColorRange.
