public interface Parser—Basic interface for SAX (Simple AP for XML) parsers.
All SAX parsers must implement this basic interface: It allows applications to register handlers for different types of events and to initiate a parse from a URI, or a character stream.
All SAX parsers must also implement a zero-argument constructor (although other constructors are also allowed).
SAX parsers are reusable but not re-entrant: The application may reuse a parser object (possibly with a different input source) once the first parse has completed successfully, but it may not invoke the parse() methods recursively within a parse.
