/** simple encode/decode */
public void testSimple() throws Exception {
Directory dir = newDirectory();
int bitsPerValue = DirectWriter.bitsRequired(2);
IndexOutput output = dir.createOutput("foo", IOContext.DEFAULT);
DirectWriter writer = DirectWriter.getInstance(output, 5, bitsPerValue);
writer.add(1);
writer.add(0);
writer.add(2);
writer.add(1);
writer.add(2);
writer.finish();
output.close();
