1. normally you should include whatever error messages you see, or explain
what you know "does not work"
2. the javadoc says:
public static ArrayAbstract factory(java.lang.Object javaArray)
Generate a new Array from a java multidimensional array of primitives.
This makes a COPY of the data values of javaArray.
since it makes a copy of the array, you need to fill the array before you
write it. Im not sure if this is your problem.
3. I assume you are interested in writing strings. (for byte data, use
ArrayByte, not ArrayChar)
heres how to write a 2D char array:
// write char variable
int[] origin = new int[2];
ArrayChar ac = new ArrayChar.D2(n, len)
ima = ac.getIndex();
String val = "Testing 1-2-3";
for (j=0; j<val.length(); j++)
ac.setChar(ima.set(j), val.charAt(j));
try {
ncfile.write("svar", origin1, ac);
} catch (IOException e) {
System.err.println("ERROR writing Achar");
assert(false);
}
I realize this is obscure, so Ive added some new helper classes into
ArrayChar (release 2.10 now avail).
Example, assuming you want to write a single string
ArrayChar ac2 = new ArrayChar.D1(str_len);
ac2.setString( "Yer String here");
// write String
try {
ncfile.write("StringVariable", origin, ac2);
} catch (IOException e) {
}
Example, assuming you have an array of n Strings with maximum length
max_len:
String s[n];
ArrayChar ac2 = new ArrayChar.D2(n, max_len);
ac2.setString( 0, s[0]);
ac2.setString( 1, s[1]);
ac2.setString( 2, s[2]);
// write String array
try {
ncfile.write("StringArray", origin, ac2);
} catch (IOException e) {
}
