The test case below should demonstrate the bug pretty well. Note that it
did not exist in 4.0.
import java.io.File;
import java.io.IOException;
import ucar.ma2.Array;
import ucar.ma2.DataType;
import ucar.ma2.InvalidRangeException;
import ucar.nc2.Dimension;
import ucar.nc2.NetcdfFile;
import ucar.nc2.NetcdfFileWriteable;
public class Foo {
public static void main(String[] args) throws IOException,
InvalidRangeException {
File tempFile = File.createTempFile("foo", "nc");
tempFile.deleteOnExit();
NetcdfFileWriteable ncWriteable =
NetcdfFileWriteable.createNew(tempFile.getAbsolutePath(), false);
try {
Dimension timeDim = ncWriteable.addUnlimitedDimension("time");
ncWriteable.addVariable("time", DataType.INT, new
Dimension[]{timeDim});
ncWriteable.addVariableAttribute("time", "units", "hours
since 1990-01-01");
ncWriteable.create();
Array timeData = Array.factory(DataType.INT, new int[]{1});
int[] time_origin = new int[] {0};
for (int time = 0; time < 10; time++) {
timeData.setInt(timeData.getIndex(), time * 12);
time_origin[0] = time;
ncWriteable.write("time", time_origin, timeData);
}
// Prints "0 12 24 36 48 60 72 84 96 108", the expected result.
System.out.println(ncWriteable.readSection("time"));
} finally {
ncWriteable.close();
}
NetcdfFile ncFile = NetcdfFile.open(tempFile.getAbsolutePath());
try {
// Prints "0 0 12 0 24 0 36 0 48 0".
System.out.println(ncFile.readSection("time"));
} finally {
ncFile.close();
}
}
}
