Passing an array or List type works, as @dmon answered.

For sake of completeness, there is also an incremental approach if you wanted to read contents one-by-one:

Iterator it = mapper.reader(Objects.class).readValues(in);
while (it.hasNext()) {
  Objects next = it.next();
  // ... process it
}

This is useful if you have huge lists or sequences of objects; either with enclosing JSON Array, or just root-level values separated by spaces or linefeeds.
