Does it support Composition relationship(The solid diamond) is class diagram? Thanks.
Since Composition is a stronger form of aggregation, you have to first establish aggregation relationship between two classes. Use Tools > Create > Aggregation for aggregation control. Once you have established aggreation relationship between two classes, right click on the aggregation link and then change the containment to either by value or by reference from unspecified to display composition relationship.
