I'm using VisAD to model database tables and have a question.
Let a db table have an id, an x and an y coord, and a few other fields
like temperature, pressure etc.
I create a MathType like
(id -> (x,y,temp,pressure,...)
(that is RealType -> (RealTupleTypes)).
Used a Linear1DSet as domain of a FlatField and got the points all right
on the display. Here a snippet:
TupleType range_tuple = ...;
RealType index = RealType.getRealType( "id" );
FunctionType func_i_xy = new FunctionType( index, range_tuple );
Set index_set = new Integer1DSet(index, count);
FlatField vals_ff = new FlatField( func_i_xy, index_set );
Now I have another type of geometry, rather than single points, much like
the 2D Set found in Region.java, which defines a polygon:
int tris = DelaunayCustom.fill(samples);
DelaunayCustom delaunay = new DelaunayCustom(samples, tris);
Irregular2DSet region =
new Irregular2DSet(earth, samples, null, null, null, delaunay);
which I also want to fill.
So I changed the type to
(id ->( (x,y) , temp, pressure, ...))
(x,y) is a RealTupleType.SpatialCartesian2DTuple, whereas the other fields
are RealTypes (defined by float).
To the question: what method setSample do I need? If that makes sense at
all. Or do I have to wrap ((x,y),temp,pressure,...) in some visad.Data
Thanks in advance,
