Yes I have "EQSymbol" StainCrossSymbol etc., and corresponding entries in the
stationsymbols.xml. But those only draw symbols in the station model editor,
right?
At least they did in the old version. I need code such as is (or was) in
StationModelDisplayable.java and ShapeUtility.java that draws the point obs in the main
display.
Yes, they should show up in the station model editor. What you want to
do is to move the code that created
the visad geometry arrays into methods in EQSymbol, StrainCrossSymbol, etc.
Look at ucar.unidata.ui.symbol.LabelSymbol
The idea is that the StationModelDisplayable looks at each MetSymbol in
the station model.
If the MetSymbol returns false in the call doAllObs (the default) the
displayable tries to find the
data objects in the point ob that correspond to the parameter name of
the MetSymbol.
If it cannot find them then it skips that symbol.
If the MetSymbol returns true from doAllObs then the displayable simply
passes the point ob to the met symbol
which returns the shapes to use. e.g.:
if (metSymbol.doAllObs()) {
shapes = metSymbol.makeShapes(ob);
} ...
else the displayable handles the creation of the shape array for known
MetSymbol classes (e.g.,
WindBarbSymbol, WeatherSymbol, etc.) If it doesn't know how to handle
the MetSymbol
it calls the method:
} else {
//Default is to ask the symbol to make the shapes
shapes = metSymbol.makeShapes(dataArray, ob);
}
I hope that clears things up.
