GXVM class.
In-memory vector data methods
The `GXVM <geosoft.gxapi.GXVM>` class will store vector (array) data in a memory buffer which
can be accessed using the `GXVM <geosoft.gxapi.GXVM>` methods.
The main use for the `GXVM <geosoft.gxapi.GXVM>` class is to store data in a single physical
memory location. This memory can then be accessed by a user DLL using
the `GXGEO.get_ptr_vm <geosoft.gxapi.GXGEO.get_ptr_vm>` function defined in gx_extern.h.
`GXVM <geosoft.gxapi.GXVM>` memory can be any size, but a `GXVM <geosoft.gxapi.GXVM>` is intended for handling relatively
small sets of data compared to a `GXVV <geosoft.gxapi.GXVV>`, which can work efficiently with
very large volumes of data. The acceptable maximum `GXVM <geosoft.gxapi.GXVM>` size depends on
the operating system and the performance requirements of an application.
The best performance is achieved when all `GXVM <geosoft.gxapi.GXVM>` memory can be stored
comfortably within the the available system RAM. If all `GXVM <geosoft.gxapi.GXVM>` memory
will not fit in the system RAM, the operating system virtual memory
manager will be used to swap memory to the operations systems virtual
memory paging file. Note that the operating system virtual memory
manager is much slower than the manager used by Geosoft when working with
very large arrays in a `GXVV <geosoft.gxapi.GXVV>`.
See `GXVV <geosoft.gxapi.GXVV>` for methods to move data between a `GXVM <geosoft.gxapi.GXVM>` and a `GXVV <geosoft.gxapi.GXVV>`.
