I don't know how to do this in your tool of choice, but on the model level, it works exactly like for classes. You create a template operation with your signature. Chapter 17.4.14 of the <a href="http://www.omg.org/spec/UML/" rel="noreferrer">UML2 superstructure</a> specifies this for notation: <blockquote> The template parameters and template parameter binding of a template operation are two lists in between the name of the operation and the parameters of the operation. *<visibility> <name> ‘<‘ <template-parameter-list> ‘>’ ‘<<‘ <binding-expression-list> ‘>>’‘( ‘ <parameter> [‘,’<parameter>]** ‘)’ [‘:’ <property-string>] </blockquote> In your case, let's first see the simple case of <pre><code>public <T> boolean bar(T x, T y) </code></pre> This would correspond to <blockquote> + bar<T> (x: T, y: T) : Boolean </blockquote> Your original example looks a bit more complicated because the template parameter is constrained to another class, Comparable, that in turn is also a template whose parameter (I'll call it T1) is bound to the operation's parameter in turn. This gives us <blockquote> + bar<T > Comparable<T1->T>> (x: T, y: T) : Boolean </blockquote> Note: (A bit of in-depth rambling ahead) Templates as specified by UML (and to some degree C++) are a very different beast from Generics in Java. They look more or less the same, but there are - sometimes subtle - differences in their semantics that can make it difficult to match the two. The most important one in UML is this: <blockquote> A template cannot be used in the same manner as a non-template element of the same kind. The template element can only be used to generate bound elements (e.g., a template class cannot be used as the type of a typed element) or as part of the specification of another template (e.g., a template class may specialize another template class). </blockquote> This means that in UML, OtherFoo needs to be a template, too - i.e. have a template signature (with 0 parameters). In order to then use the operation template correctly outside the template scope - i.e. call it in an activity or similar - you'd first have to bind it to a concrete operation, which is used instead. In case of your example, this means: <ol> <li>Binding OtherFoo template to an (anonymous) bound class.</li> <li>Binding bar operation template to an operation in the bound class.</li> </ol>

1. COI find this info very useful, is clear as crystal, thanks. It will be great for future readers if you could add a graphic of the two latest examples as JonSkeet did in his answer (check the link on my question).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
