Generalizations

Here is an example of a generalization relationship.

    R38
    Bank Level +
        Top Bank Level
        Middle Bank Level
        Bottom Bank Level
    <subclass>.(Bank, Floor) -> Bank Level.(Bank, Floor)
--

And here's a snippet from the generated diagram:

Here we are specifying the superclass, subclasses and the referential attribute formalization using this grammar:

// Generalization
gen_rel = superclass subclasses genref // A generalization relationship
superclass = INDENT icaps_name SP? "+" EOL* // A superclass class name
subclasses = subclass+
subclass = INDENT INDENT icaps_name EOL*  // A subclass class name

// Genref
genref = single_line_genref / binref+ // Either abbreviated <subclass> source or explicit source for each subclass
single_line_genref = INDENT allsubs_attrs SP '->' (WRAP / SP) target_attrs EOL* // Abbreviated in a single line
