@Override
@SuppressWarnings({ "rawtypes", "unchecked" })
protected void writeMap(Schema schema, Object datum, Encoder out)
throws IOException {
if (writeDirtyBits) {
// write extra state information for maps
StatefulMap<Utf8, ?> map = (StatefulMap) datum;
out.writeInt(map.states().size());
for (Entry<Utf8, State> e2 : map.states().entrySet()) {
out.writeString(e2.getKey());
out.writeInt(e2.getValue().ordinal());
}
