The Value The Value of of UML ModelsUML Models
What to do with UML Models?Send to a colleque for implementationSend to a partner for coordinationSend to a standardization committee
Generate documentationGenerate codeGenerate XML schema

The Value The Value of of InterchangeInterchange
Model ExchangeCommunicate from one Organization to another
Investment securityMigrate from one Vendor to another
Value-adding Chains of ToolsWhiteboard toolModeling toolCode Generation toolsValidation, Testing and Verification tools
Dr. Marko Boger
XMIXMI
XML Metadata Interchange (XMI)Based on XML Standardized by OMGUsed for highly referential Data E.g. MetadataProductions rules for MOF
Supported by many VendorsSaving Format of Poseidon
Dr. Marko Boger
Problems Problems with with XMIXMI
Problems with XMIDifferent Versions of XMI (1.0 – 1.2)Different Versions of MOF (1.0 – 1.4)Different Versions of UML (1.1, 1.3, 1.4)Different Interpretations Faulty Implementations
No Diagram InformationOnly the Model Information is included

Template-basedVelocity Project of ApacheTemplate-Language
• #if• #foreach• Variables: $var• Java Classes: $myClass
Design an examle file• Java, C++, HTML, XML, XML-Schema
Replace variable parts with model info.

Example for Example for HTMLHTML
<HTML><BODY>Hello $customer.Name!<table>
#foreach( $product in $catalog.productlist )#if ( $customer.hasPurchased($product) )
<tr><td>
$product.getTitle( )</td>
</tr>#end
#end</table>

How How Velocity Velocity worksworks
Establish Context, use in Templates
Context
public class $clazz.getName() {#foreach( $attribut in $attributes)private $attribut;
#end}
Template
public class Car {private kfz;private color;
}
clazz
...
attributes Vector attributes = {kfz, color}
MClassifier clazz = new MClassifierImpl(“Car“)
Java
Dr. Marko Boger
Changing TemplatesChanging Templates
Add simple metric to each classCount number of methods. If too many, generate a warning in header
/** Java class "${className}.java" generated from Poseidon for UML.* Poseidon for UML is developed by Gentleware.* Generated with velocity template engine.*/#if (preparedOperations.size()>10)
// This class has too many operations. Consider a refactoring.#end
#if ($package != "")package $package;#end
#renderImports($imports)
#renderClassSignature($preparedClassifier)
Dr. Marko Boger
Changing TemplatesChanging Templates
Add log information to MethodCall Logmanager before every method call
#macro (renderOneOperation $currentOp $editable)$currentOp.getDocs()${visibility}${static}${final}${returnType} ${name}($inOutPars)$thrownClause {
LogManager.log.info("calling method ${name}()");#renderMethodBody($currentOp.getMethodBody() $currentOp.hasReturnType())
} // end ${name}#end
