GTable1D

GTable1D

GENIUS allows to display (and read/write !) one dimension tables (abscissa et ordinate). The idea is to be able to manage one or several tabulated functions y_i = f(x_i) as, for example C_x et C_z depending on the Angle of Attack …

To do it, we must use GEntryRealVector class (or GEntryIntVector, GEntryDateVector) to store data by columns.

GUnit[] unitAng = {new GMetricUnit("deg"), new GMetricUnit("rad")};
 
double[] incVal  = {Math.toRadians(10.),   Math.toRadians(15.),   Math.toRadians(20.),
		    Math.toRadians(25.),   Math.toRadians(30.),   Math.toRadians(35.),
		    Math.toRadians(40.)};
double[] cxVal   = {0.100, 0.150, 0.200, 0.250, 0.350, 0.450, 0.600};
double[] czVal   = {0.250, 0.300, 0.350, 0.400, 0.500, 0.550, 0.600};
 
incTabIhm = new GEntryRealVector("Angle Of Attack", incVal, unitAng);
incTabIhm.setNameInConfigFile("AOA");
CxTabIhm = new GEntryRealVector("Cx", cxVal);
CzTabIhm = new GEntryRealVector("Cz", czVal);
CzTabIhm.addGInterval(errInterval);

Then we will use GTable1D class to assembly them:

aeroTabIhm=new GTable1D("Cx/Cz = f(Mach)", TableOrientation.VERTICAL,incTabIhm, CxTabIhm, CzTabIhm);
aeroTabIhm.setConstraint(new GConstraint(GConstraint.newline()));

At last, if we want to get the content of this table, we will have to use the getGVector() method then getValue() or getValueArray() methods. The following example gives us a method to recover a double table:

public double[] getData ( int rank ) {
   double[] tmp = new double[aeroTabIhm.getGVector(rank).size()];
   for (int i = 0; i < tmp.length; i++) {
      tmp[i] = (Double)aeroTabIhm.getGVector(rank).getValue(i);
   }
   return tmp;
}

Note that, it is mandatory to cast the data as, since the V1.2 version, it is possible to get objects as GEntryDateVector in GTable1D, so the getGVector() will return a table of Objects rather than a table of Number as previously.
