E093 Class Is Not Superclass Constraint
Umple semantic error raised when a class is not the superclass of a given class as defined by a constraint
Model constraints can be applied to Umple classes to ensure they respect certain properties, as defined in their constraints. This error is raised if a class is not the superclass of a given class as expected from the constraint.
Example
//The error is produced, the
//constraint is not respected because
//A is not a superclass of B
//Alternative syntax in comment
class A {
//[model: A parent of B]
[model: A superclass B]
}
class B {
}
Load the above code into UmpleOnline
Solution to The Above So the Message No Longer Appears
//The constraint is now respected
//and the error does not occur
class A {
[model: A superclass B]
}
class B {
isA A;
}
