public A startArray() {
    return null;
  }
Indicates the beginning of an array in the JSON input. This method will be called when reading
the opening square bracket character (<code>'['</code>).
<p>
This method may return an object to handle subsequent parser events for this array. This array
handler will then be provided in all calls to {@link #startArrayValue(Object)
startArrayValue()}, {@link #endArrayValue(Object) endArrayValue()}, and
{@link #endArray(Object) endArray()} for this array.
</p>

@return a handler for this array, or <code>null</code> if not needed
