The Java Operation mapped directly to the UML Operation is done with the stereotype «JavaOperation». This stereotype is optional, so if the UML class has no stereotype Java CE treats it as a Java Operation. If no appropriate property is found in UMLOperation, modifiers are mapped into UML Property properties or to the Java language properties. The Java Operation return type is mapped to the UML Type property of the UML Parameter with the “Return“ direction kind. Java Operation parameters are mapped to the UML Parameters. The direction kind is set “In“ for “final” parameters. Note that Java parameter type modifiers are mapped to the UML specific property “Type Modifier,“ but not to the UML Multiplicity.
Operation mapping table
| Java Element | UML Element |
|---|---|
| Operation declaration | UML Operation, owned by UML Class, with stereotype «JavaOperation» (optional) |
| Operation Name | UML Operation Name |
Operation documentation | UML Operation Documentation |
| Parameters list | UML Operation “Parameters” list |
| Return type | Mapped to the UML Parameter type with “return“ direction kind, i.e., it resides in the UML Operation parameters list. It is a reference to the UML Classifier; its package structure and name represent the referenced Java class |
| Return type modifiers | Mapped to the MagicDraw specified property “Type Modifier“ |
| Visibility modifier | UML Operation “Visibility” property |
| Final modifier | UML Operation “Is Leaf“ property |
| Abstract modifier | UML Operation “Is Abstract“ property |
| Static modifier | UML Operation “Is Static“ property |
| Synchronized modifier | UML Operation “Concurrency“ kind “guarded” |
| Throws list | UML Operation “Raised Exception“ list. It is a list of references to the UML Classes; its package structure and name represent the referenced Java exception class. |
| Native modifier | Java Language property “Native modifier” |
| Strictfp modifier | Java Language property “Strictfp modifier” |
Parameter mapping table
| Java Element | UML Element |
|---|---|
| Parameter declaration | UML Parameter, owned by UML Operation, with stereotype «JavaParameter» (optional) |
| Parameter name | UML Parameter Name |
Parameter documentation | When used in JavaDoc preprocessing, it is mapped to the UML Parameter Documentation. If not, it is part of the UML Operation Documentation. |
| Return type | Mapped to the UML Type property. It is a reference to the UML Classifier; its package structure and name represent the referenced Java exception class. |
| Return type modifiers | Mapped to the MagicDraw specified property “Type Modifier“ |
| Final modifier | Direction kind “in“ of the UML Parameter |
