Are all these structures thread safe?

Hi guys, I'm wondering whether I should use RWMutex with the structures? I'm working on a concurrent application.
Thanks very much!

@zhaoxy2850 No, they are not. Thread safety is not a concern of this project. This should be handled at a higher level, hence use of RWMutex to wrap GoDS insertion/retrieval methods is the way to go.

Thanks!

@emirpasic Does this these data structures are safe for concurrent reads? (e.g. with an iterator?)
