Examples of org.w3c.css.sac.Parser

org.w3c.css.sac.Parser
Basic interface for CSS (Simple API for CSS) parsers.
All CSS 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 CSS parsers must also implement a zero-argument constructor (though other constructors are also allowed).

CSS 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.
