Question between aggregations, compositions, references (arrow) and simple link (nothing) relations within UML2 ?
- by Rushino
Hello,
I have some questions regarding relations between aggregations, compositions, references (arrow) and simple link (nothing) relations within UML2 ?
If A - B - C each have composition relationship. Are the root responsable of creation and destruction of the object B and C ?
What aggregations have that the simple link or references doesn't ? What make them different ?
Thanks.
Edit: The question was a bit unclear and not objective. I edited it.
