Prof van Oosterhout, also from UEA's School of Environmental Sciences, said: "Each supertype
protects the host against a specific group of parasites, and these supertypes
were common across populations, and species, irrespective of the location.
Identification of peptide vaccine candidates for prostate cancer patients with HLA-A3 supertype
DRB1-0101 was the highest binding allele of MHC II supertype
In addition, every supertype
is "determined by aspect, mood, or tense" (178).
The implementation can be a single table collapsing all states together and containing all possible attributes,or the implementation might occur as a table one-for-one for each subtype with the supertype
related columns repeated inside each one of the subtype tables.
For example, syllables can be classified according to the type hierarchy (16) in Figure 19, in which the unadorned syllable label a represents the supertype
, the union of all possible syllable types.
The Measurement and Observation Pattern , is applied using a new type Observation that acts as a supertype
to a measurement and a qualitative observation.
We can see from the definitions of x that its type must be a supertype
of both I and J, and further from the two uses, it must be a subtype of both SI and SJ.
ENTITY SETUP_LINE_DEF SUPERTYPE

Subtyping is necessary when clarity is required about the data (and to some respect, the behavior) of the Supertype
In fact, it only paraphrases a common constraint on subtyping, namely that the extension of a supertype
is totally covered by the extensions of its subtypes, thus rendering the supertype
a mere abstraction.
For example, in Orion the type of an instance variable can only be replaced by a supertype
in the type hierarchy.
