[webkit-dev] question on Structure.

[PandaCanFly]

Hi, all.
    I am reading the implementation of JavascriptCore. I think Class Structure, Class JSCell, Class JSObject are the point to understand other codes. 
    The member functions of Structure whose name is addPropertyTransition, addPropertyTransitionToExistingStructure, really confuse me. In my opinion, new object transition is same to the parameter structure. What's the functionality of transition? 
    Thanks for your attention~
