And I have one more problem:
So here's the deal, I can't have all the data that I'm going to write in
memory, So I'm writing each value 1 by 1 in this way:
I call addValue with the index (which is the n-dimensional position), the
value and the variable.
this works great for numbers:
private void addDoubleValue4d(int[] index, Double value, Variable var)
throws IOException, InvalidRangeException {
Preconditions.checkArgument(index.length==4);
//Shape for 1 value in a 4 dimensional space
ArrayDouble arrAmp = new ArrayDouble(new int[]{1, 1, 1, 1});
arrAmp.setDouble(0, value);
nc.write(var.getName(), index, arrAmp);
}
Now, when it comes to String values I would expect it to work the same way:
private void addStringValue2d(int[] index, String value, Variable var)
throws IOException, InvalidRangeException {
Preconditions.checkArgument(index.length==2);
//Shape for 1 value in a 2 dimensional space
ArrayObject arrAmp = new ArrayObject(String.class,new int[]{1, 1});
arrAmp.setObject(0, value);
nc.writeStringData(var.getName(), index, arrAmp);
}
But writeStringData gets he shape of the var (4x2) and then tries to access
an illegal position (2).
It seems that the problem is that strlen in writeStringData is not computed
with Math.min(array.getSize(), v2.shape[rank -1])
int strlen = v2.shape[rank-1];
// turn it into an ArrayChar
ArrayChar cvalues = ArrayChar.makeFromStringArray((ArrayObject) values, strlen);
I would have made the change on my own but there is no test suit (at least I
couldn't find it) so I'm not sure of the impact of such a change.
