Instead of using low level com.nomagic.uml2.ext.jmi.helpers.StereotypesHelper API to access information about profile elements, it is possible to generate a profile implementation class out of the UML Profile model. This implementation class wraps all mapping, naming details with a nice Java API. MagicDraw comes with already generated profiles implementation for standard profiles. See Standard profiles implementation page for details.
To create your own custom profile implementation you need to follow these steps
- Install Development Tools plugin from Help->Resource Manager
- Open UML Profile model with MagicDraw.
- Generate profile implementation code using Tools->Development Tools->Generate Profile Class Implementation (wrappers) ...
Profile implementation class has these features
- There is a constant defined for every DataType, Enumeration name
- There is a getter for every DataType element defined in the profile
- Java enumeration is generated for every Enumeration element defined in the profile. This class has following features
- There are methods to get enumeration literals by generated enumeration and vice versa
- Inner java class is generated for every Stereotype defined in the profile. This class has following features
- There is a constant defined for Stereotype name
- There are constants defined for all stereotype tags names
- There is a setter/getter method available for every stereotype tag. Signature of these methods corresponds to tag multiplicity type and etc. No more need to work with strings and casting values to primitives as in StereotypesHelper case.
- There is a check method to check if Element has specific stereotype applied
- There is a getter for Stereotype element itself
It is highly recommended to assign URI to Profile element in the UML model before generation. URI is an unique Profile identifier and helps to avoid conflicts if model has several profiles with same name applied.
Custom sample profile
Usages example
Element element = ...; CustomProfile customProfile = CustomProfile.getInstance(element); //check if element has Person stereotype applied customProfile.person().is(element); //get Person.country tag value String country = customProfile.person().getCountry(element); //set Person.country tag value customProfile.person().setCountry(element, "US");
