7.7 Modeling Classification Hierarchies Using Generalization

All classifiers can appear on a block definition diagram, which means that they can be organized into a classification hierarchy. The classifiers so far encountered in this chapter are blocks, value types, interfaces, interface blocks, and signals. In a classification hierarchy each classifier is described as being more general or more specialized than another. Typically a general classifier includes a set of features common to a set of more specialized classifiers that also include additional features. The relationship between the general classifier and specialized classifier is called generalization. Different terms are used to identify the classifiers at the end of a generalization ...
