 | CVV Class |
The VV class stores very long vector (array) data (such
as channel data from an OASIS database) in memory and
performs specific actions on the data. This set of
functions is similar to the VM functions except that
you cannot access data directly and therefore you cannot
use a VV to pass data to an external (non-Geosoft)
Dynamic Link Library (DLL) object function.
If you want to pass data to a DLL, you must move a subset
of the data stored in memory to a small vector object and
then use the GetPtrVM_GEO function to pass a pointer to the
data on to the external function.
See VVU for more utility methods.
