HydroCouple::IQuality Class Reference

Qualitative data described 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. More...

Detailed Description

Qualitative data described 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.

Returns

An 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.

For qualitative data the IComponentItem data exchanged between IComponents contains one of the possible ICategory instances per element in the IComponentItem involved.

Examples:

• Colors:
  • red
  • green
  • blue
• Land use:
  • nature
  • recreation
  • industry3
  • infrastructure
• Rating:
  • worse
  • same
  • better

Constructor & Destructor Documentation

~IQuality()

virtual HydroCouple::IQuality::~IQuality ( )

pure virtual

IQuality::~IQuality is a virtual destructor.

Member Function Documentation

categories()

virtual vector<hydrocouple_variant> 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.
