| <h2>Introduction</h2> | |
| <p>There are two main benefits in familiarizing yourself with UML templates: firstly, | |
| you can express and communicate your ideas more accurately, and secondly, code | |
| generated via conversion through Ecore will result in generically specified | |
| Java.<span style='mso-spacerun:yes'> </span>Through a series of examples, this | |
| article attempts to explain how templates in UML map to generics in Ecore and | |
| Java.<span style='mso-spacerun:yes'> </span></p> | |
| <p>Some concepts involving generics in UML do not map directly to Java (or | |
| Ecore).<span style='mso-spacerun:yes'> </span>In general, UML is more verbose | |
| and requires a modeler to create more constructs to convey ideas that would | |
| otherwise be more simply described in Java (or Ecore).</p> | |
| <p>Consider template bindings for example: template bindings are constructs | |
| that do not explicitly exist in Java (or Ecore).<span | |
| style='mso-spacerun:yes'> </span>The template binding concept in UML can be | |
| considered to be a merging of <span class=SpellE>templateable</span> items | |
| into the bound item where actual parameters are substituted for formal | |
| parameters.<span style='mso-spacerun:yes'> </span>More about this in the | |
| section entitled <a href="#_Some_UML_Basics">Some UML Basics</a>.</p> | |
| <p>Concrete classifiers that result from applying template bindings to a <span | |
| class=SpellE>templated</span> classifier can also be considered an artificial | |
| construct required by UML.<span style='mso-spacerun:yes'> </span>Such | |
| additional classifiers are not needed when describing generics in Java (or | |
| Ecore).<span style='mso-spacerun:yes'> </span>The examples listed later in | |
| this document will explain these ideas in detail.</p> | |
| <p><o:p> </o:p></p> | |
| <h2>Enhanced Ecore Profile</h2> | |
| <p>The mapping from UML to Ecore as implemented in the UML2 2.1 API is intended | |
| to be a lossless conversion.<span style='mso-spacerun:yes'> </span>Round | |
| tripping from UML to Ecore and back again should produce the original UML | |
| model.<span style='mso-spacerun:yes'> </span>To achieve this lossless | |
| conversion, concepts present in Ecore, but not in UML have been added to an | |
| enhanced Ecore profile.<span style='mso-spacerun:yes'> </span>The information | |
| added to stereotyped items will be reapplied when converting back.</p> | |
| <p>What UML does not capture that Ecore does:</p> | |

| pointed out that it is possible to specify a single bound on type parameters in | |
| UML via the <span class=SpellE>ClassifierTemplateParameter::constrainingClassifier</span> | |
| property but this is currently a scalar value).<span style='mso-spacerun:yes'> | |
| </span>The <<<span class=SpellE>eGenericType</span>>> stereotype | |
| has been created for this purpose.</p> | |
| <p style='margin-left:.5in;text-indent:-.25in;mso-list:l10 level1 lfo2; | |

| requires additional classifiers to specify bound generic types.<span | |
| style='mso-spacerun:yes'> </span>These need to be marked in order to remove | |
| them when converting from UML to Ecore.<span style='mso-spacerun:yes'> | |
| </span>The <<<span class=SpellE>eGenericType</span>>> stereotype is | |
| used as a marker so that conversion from UML to Ecore will result in dropping | |
| elements with such stereotypes.</p> | |

| <p>While we are on the topic of differences between Ecore and UML we should | |
| mention that UML has some quirkiness in the area of templates.<span | |
| style='mso-spacerun:yes'> </span>In the current version of the UML | |
| specification, UML has multiple actual parameters per formal parameter.<span | |
| style='mso-spacerun:yes'> </span>It is unclear how multiple parameters could | |
| be substituted for one formal parameter.<span style='mso-spacerun:yes'> | |
| </span>The conversion process therefore considers only one actual per formal | |
| parameter.<span style='mso-spacerun:yes'> </span>An <a | |
| href="http://www.omg.org/issues/uml2-rtf.open.html#Issue9398">issue</a> for | |
| this has been raised at OMG and should be resolved by the next revision of the | |
| UML specification.</p> | |
| <p><o:p> </o:p></p> | |
| <h2><a name="_Some_UML_Basics"></a>Some UML Basics</h2> | |
| <p>UML allows users to model generics via templates and template bindings.<span | |
| style='mso-spacerun:yes'> </span>Section 17.5 of the UML superstructure specification | |
| describes all the constructs required to describe templates.</p> | |
| <p>Quoting from the UML superstructure specification </p> | |
| <p><i style='mso-bidi-font-style:normal'>A <span class=SpellE>TemplateableElement</span> | |
| that has a template signature is a specification of a template.<span | |

| relationships.<span style='mso-spacerun:yes'> </span><span class=SpellE>TemplateableElements</span> | |
| can have template signatures and template bindings.<span | |
| style='mso-spacerun:yes'> </span>Thus a <span class=SpellE>templateable</span> | |
| element may be both a template and a bound element.<span | |
| style='mso-spacerun:yes'> </span>The template parameters for the template | |
| signature specify the formal parameters that will be substituted by actual | |
| parameters in a binding.<o:p></o:p></i></p> | |
| <p><i style='mso-bidi-font-style:normal'>A template cannot be used in the same | |
| manner as a non-template element of the same kind.<span | |
| style='mso-spacerun:yes'> </span>The template element can only be used to | |
| generate bound elements or as part of the specification of another | |
| template.<span style='mso-spacerun:yes'> </span>A bound element is an ordinary | |
| element and can be used in the same manner as a non-bound element of the same | |
| kind.<span style='mso-spacerun:yes'> </span></i>This is an important point | |
| since it means that a template class cannot be used as the type of a typed | |
| element.</p> | |
| <p><span class=SpellE><i style='mso-bidi-font-style:normal'>ParameterableElement</i></span><i | |
| style='mso-bidi-font-style:normal'> is an element that can be exposed as a | |
| formal template parameter for a template or specified as an actual parameter in | |

| class=SpellE>ParameterableElement</span> may be part of the definition of a | |
| template parameter.<span style='mso-spacerun:yes'> </span>In an element bound | |
| to the template, any use of the template parameter will be substituted by the | |
| use of the actual parameter.<span style='mso-spacerun:yes'> </span>If a <span | |
| class=SpellE>ParameterableElement</span> is exposed as a template parameter, | |
| then <span class=SpellE>parameterable</span> element is only meaningful within | |
| the template.<o:p></o:p></i></p> | |
| <p><i style='mso-bidi-font-style:normal'>A <span class=SpellE>TemplateBinding</span> | |

| element and a template.<span style='mso-spacerun:yes'> </span>A template | |
| binding specifies the substitutions of actual parameters for the formal | |
| parameters of the template.<span style='mso-spacerun:yes'> </span>The presence | |
| of a template binding relationship implies the same semantics as if the | |
| contents of the template owning the target template signature were copied into | |
| the bound element, substituting and elements exposed as formal template | |
| parameters by the corresponding elements specified as actual parameters in the | |
| binding.<o:p></o:p></i></p> | |
| <p>The kinds of UML metatypes that can be <span class=SpellE>templateable</span> | |
| are Classifier (Class, Component etc.), Operation, Package and less commonly, | |

| style='mso-bidi-font-style:normal'>Iterator_E</i></span>.<span | |

| </span>UML does not allow us to use templates as the type of an <span | |

| property which is an <span class=SpellE><i style='mso-bidi-font-style:normal'>ArrayList</i></span> | |
| of Cars.<span style='mso-spacerun:yes'> </span>Again, we create a new class <span | |
| class=SpellE><i style='mso-bidi-font-style:normal'>ArrayList</i>_<i | |

| </span>It is possible to specify upper and lower bounds on such wildcards.<span | |
| style='mso-spacerun:yes'> </span>When we talk about bounds, we refer to the | |
| ability to specify that bindings to a generic type parameter must either be the | |

| style='mso-spacerun:yes'> </span>In this way, tighter restrictions can be | |
| placed on acceptable bindings.<span style='mso-spacerun:yes'> </span>In | |
| addition to tightening restrictions, upper bounds (extends) are particularly | |
| useful for ensuring that substitutions will have features that are required by | |
| the template for its behavior.<span style='mso-spacerun:yes'> </span>For | |
| example, one might have <i style='mso-bidi-font-style:normal'>List<E extends | |

| <p>Congratulations! Youve made it this far, if youve followed through the | |
| examples, you will no doubt have discovered that the UML representation is | |
| verbose and intricate in comparison to Ecore or Java.<span | |
| style='mso-spacerun:yes'> </span>Hopefully, with a bit of practice, the UML | |
| representation will become second nature.<span style='mso-spacerun:yes'> | |
| </span>This article really only scratches the surface of the intricate possible | |
| scenarios one may create when working with generics.<span | |
| style='mso-spacerun:yes'> </span>By using templates in UML you can express | |
| and communicate your ideas more accurately, and code generated via conversion | |
| through Ecore will result in generically specified Java.</p> | |
