Use Function::interpolate() to access the values. Often, one can
avoid ever needing to access the values directly, but if they should
be needed, then it is possible to either interpolate the Function to a
given Cell (getting the expansion coefficients in the local finite
element basis) or get the values at all vertices.

So, try to avoid accessing the values but if you really need the
values at vertices you can still get them.
