Detailed Description

IQuality describes qualitative data, where a value is specified as one category within a number of predefined (possible) categories. These categories can be ordered or not.

Qualitative data describes items in terms of some quality or categorization that may be 'informal' or may use relatively ill-defined characteristics such as warmth and flavour. However, qualitative data can include well-defined aspects such as gender, nationality or commodity type.

For qualitative data, the IComponentDataItem data exchanged between components contains one of the possible category instances per element in the IComponentDataItem involved.

Examples:

Colors: red, green, blue
Land use: nature, recreation, industry, infrastructure
Rating: worse, same, better

Constructor & Destructor Documentation

◆ ~IQuality()

virtual HydroCouple::IQuality::~IQuality ( )

virtualdefault

IQuality::~IQuality is a virtual destructor.

Member Function Documentation

◆ categories()

virtual hydrocouple_variant_set HydroCouple::IQuality::categories ( ) const

pure virtual

Returns: A list of the possible ICategory allowed for this IQuality If the quality is not ordered the list contains the ICategory's in an unspecified order. When it is ordered the list contains the ICategory's in the same sequence.

◆ isOrdered()

virtual bool HydroCouple::IQuality::isOrdered ( ) const

pure virtual

Checks if the IQuality is defined by an ordered set of ICategory or not.
