<p class="MsoNormal"><span lang="EN-US">based on the generated code for the GReAT Group operator, we built up a cpp template for copying an abstract source object including its children. Since we would like to pass the copied object to an out-port within the
same rule, the approach is to create a dummy object within the rule’s effector and replace it during the AttributeMapping by calling the aforementioned template:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">The result in the transformation’s output is as intended. But, the runtime of the function UdmUtil::CopyObjectHierarchy within the template increases with every call. After several calls, the execution of UdmUtil::CopyObjectHierarchy
takes several seconds. My search within the Udm source code did not reveal any reason. This is why I would like to ask if someone could give me a hint or provide an alternative solution? For example an incorrect usage of the UdmUtil::copy_assoc_map.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">An example transformation with the necessary metamodel and inputs can be found here:

<p class="MsoNormal"><span lang="EN-US">The cpp template is located in the “UserLib_CloneObject.h”. The increasing runtime for a single “CopyObjectHierarchy” execution can be seen in the console output (Steps 2 to 3).<o:p></o:p></span></p>
