ChartWrapper and internal data

[API Developer]

Hey guys,

I'm creating a structure that implements the ChartWrapper and was wondering if someone could clarify some specifics as to why it works. Currently I hold the data (google DataTable) inside of the wrapper and use the getDataTable() and setDataTable() to access it and make small changes to it if needed. In the cases of these functions, are they returning references, does the setDataTable try to just update it, or does it create an entire copy then copy that entire copy into itself.

Javascript copies object references by default, and I haven't observed anything that would lead me to believe the API does anything differently.
