Sequence Diagram

Bugs about infinite loop and problems about movement of elements have been fixed.

Work in progress

  • Bug 529945: [Performance] Creation of new element is not done in a constant time
    • We create a small class to get easily a benchmark of the performance to create 5000 elements in the same container.
      • The best way to create 5000 Classes is to use the UML Factory. (constant time)
      • The best way to create 5000 Classes stereotyped SysML Blocks is to use the UML Factory, then the stereotype application for Block (using its factory), then adding ourself the stereotype application to the resource (constant time)
      • Using the native UML API or the Papyrus Edit Service is less efficient and not in constant time, so adding a stereotype application depends on the model's size (we filled the UML bug Bug 528925: 528925)
      • For UML element creation, the Papyrus Edit Service is less efficient than the UML factory itself, and not in constant time. We will continue to investigate on it.
      • benchmarks after applying and testing some patches:
Before patches Improving Stereotyped elements naming + SysML 1.4 patches + UML2 patches All patches
5000 blocks with service edit 206 800 ms 177 968ms 18 090ms 18 158ms (no impact using service edit?)
5000 classes + apply stereotype 81 616 N/A N/A 1058ms 915ms

In additiona, we changed the method used to calculate the name of created elements in order to increase the performance of Papyrus. A preference has been added and 3 options are now available:

  • No Index
  • quick index (default): unique in the main usecase, don't start necessary to 1.
  • unique index: the previous implementation

We informed the users on the Papyrus forum, on this thread
