[netCDFJava #SCH-111122]: Problem casting Array

Hi Philippe:

The most efficient solution:

  Array data = v.read();
  float[] fdata =(float []) data.get1DJavaArray(float.class);

this avoids copying if the data is already float.

However, you have a 1D array, not 2D. Since you are worried about efficiency, 
the fastest thing to do is to work with the 1D array (ie dont use a 2D array), 
and do the stride arithmetic yourself, so use fdata[j*nx+i] whenever you want 
f[j][i], where nx = data.getShape()[1]. Im assuming you know these are 2D 
arrays.

otherwise you have to allocate the 2D array and copy into it, in which case you 
might as well do

  Index ima = data.getIndex();
  int [] shape = data.getShape();
  for (int j = 0; j<shape[0];  j++)
    for (int i = 0; i<shape[1];  i++)
      f[j][i] = data.getFloat( ima.set(j,i)); 

Regards,

John
