public boolean hasData()
Does not advance the position.
Returns true immediately if the input stream has available data that has not yet been consumed.
On a network input stream, this may block to determine if the stream contains data or is at end-of-data.
This is used when parsing multiple elements from a stream to see if there is data or not before calling parse().
It may also be used after a parse() operation that is intended to consume the entire data stream (such as for a file) to determine if all data has been consumed or some data is left-over.
