  • Newvalue: This fits well with Ticket #45, because it will be more useful for generalized AMR reading.

The reasons for doing this are two-fold -- 1. Using a recarray means we use pointers in the individual grid files. 2. Using a recarray de-pollutes the namespace of the Hierarchy object.

  • Newvalue: No, I have changed my mind. recarray does not work for us because it is slightly less flexible. The hierarchy, even in extremely large datasets, is a large chunk of memory. But this is not the way to fix that.
