com.fasterxml.aalto.AsyncInputFeeder
Interface used by {@link AsyncXMLStreamReader} to get more input to parse.It is accessed by entity that feeds XML content to parse; at any given point only one chunk of content can be processed so caller has to take care to only feed more content when existing content has been parsed (which occurs when parser's nextToken is called). Once application using non-blocking parser has no more data to feed it should call {@link #endOfInput} to indicate end of logical input stream. @author tatu
