Functional Details

Typically, Fields have a "positions" component defining a set of points in space, a "connections" component defining the connectivity of the positions, and a "data" component containing the individual data values associated with the individual positions or connections. A Field can be manipulated by accessing these components. The following are just two examples:

Return Value Returns the name component of Field f or returns NULL and Sets an error code if f is not a Field. It does not set an error code if the component does not exist.
