The most common way for this to happen is:Īnd you delete Class B by right clicking on its icon in theīrowser window and selecting Delete, you are left with theĬlass B is no longer contained in the diagram, but the association is still present. One of your associations has no other class on the other end.
#Goland unresolved reference code#
A dangling association is when the script code is looping through the associations attached to the class you are generating code for and getting the class on the other side of the association. Unresolved Reference may be due to a dangling association. A message without an Operation will cause this error. Make sure that the messages specified in Message diagrams exists as an operation under Operations in that class. These steps will reproduce the situation above:Įrror: Unresolved reference to Operation. Use Edit > Find to find where unresolved references exist.Īctual Unresolved Error Messages that are reported, their explanations, and some possible solutionsĮrror: Unresolved reference to Operation "mumble".A possible solution for the elements containing the unresolved references is to delete (from the model) all those objects that were causing the unresolved reference errors, and put them back in the model with the corresponding Client/Supplier.Check to make sure that all objects in diagrams are instances of defined classes.If a relationship references an element in an unloaded subunit, and unresolved reference may occur. Check to see if all subunits are loaded.Possible Solutions for Unresolved References If the class does not have a corresponding method, check model will tell you. If any of the referenced items get deleted from the model, either directly by means of a delete from model command, or indirectly by means of copying portions of the design and pasting into a new design, Check Model will report an error.A Relationship references a nonexistent supplier (such as A inherits from B, but B does not exist).A link in a sequence diagram is pointing from an object to another object, but the second object does not exist.If you import the category then the reference will be resolved. An existing class references a class in the category that was deleted.
A sequence diagram has an operation that is not defined in its class.From a message on a object diagram to an operation in a class.An object to its class (The object is a type of a class present in the model.).Client/Supplier of any kind of relationship (has, uses, instantiation, metaclass, category import, module visibility, connection) exists as a model element in the model.Click the play button to run the script.Ĭheck Model checks for the following circumstances to check if unresolved references are present From within Rational Rose, navigate to Tools > Open Script.ģ. Check Model can be run by navigating to Tools > Check Model.īefore running Check Model, run the script attached to this technote which may resolve a substantial portion of the unresolved references. The same error message appears even though I have implemented the methods just a few lines above.According to the on-line help for Rational® Rose, Check Model traverses the entire model looking for unresolved references and places the results into the log. Here is a similar (but simpler) example of some code that I have found here on stackoverflow ( Go - append to slice in struct) to reproduce this issue.
While writing the code, GoLand shows me an error message such as "unresolved reference" when the reference do exist and that the program compiles and runs correctly. I am writing a project using the Go language with GoLand IDE by Jetbrains.
