E092 Class Is Not Subclass Constraint
Umple semantic error raised when a class is not the subclass 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 subclass of a given class as expected from the constraint.
Example
//The error occurs as A
//does not respect the constraint
//Alternative syntax is indicated
//in comments
class A {
//[model: A child of B]
//[model: A inherits from B]
[model: A isA B]
}
class B {
}

Solution to The Above So the Message No Longer Appears
//A respects the constraint
//and avoids the error
class A {
isA B;
[model: A isA B]
}
class B {
}
