E091 Attribute Of Type Not Found Constraint
Umple semantic error raised when a class does not contain the required attribute of a given type
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 does not contain an attribute of a specified type in the constraint.
Example
- //The error is raised, A does
- //not contain an attribute of
- //type B
- class A {
- [model: A has attribute of B]
- }
- class B {
- }
Load the above code into UmpleOnline
Solution to The Above So the Message No Longer Appears
- //A now contains an
- //attribute of type B
- class A {
- B attr;
- [model: A has attribute of B]
- }
- class B {
- }
