* This class represents information pieces expressed in categorical type of
|
40
|
* data (in opposition to {@link QuantitativeData quantitative data} on one side and to literal data on
|
41
|
* the other side). Only {@link TaxonDescription taxon descriptions} and
|
42
|
* {@link SpecimenDescription specimen descriptions} may contain categorical data.<BR>
|
43
|
* The "color of petals" {@link Feature feature} for instance can be described with
|
44
|
* {@link State state terms} such as "blue" or "white". If the color of petals of a
|
45
|
* particular tree is described as "mostly blue" and "exceptionally white" two
|
46
|
* {@link StateData state data} instances must be assigned to an instance of the
|
47
|
* present class: the first one with the state "blue" and the {@link Modifier modifier}
|
48
|
* "mostly" and the second one with the state "white" and the modifier "exceptionally".
|
49
|
* Whenever more than one state data belongs to a categorical data they should be
|
50
|
* interpreted as being related by the inclusive disjunction "or".
|
51

* <P>
|
