public interface: Parser [javadoc | source] 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.

Method from org.w3c.css.sac.Parser Summary:
getParserVersion, parsePriority, parsePropertyValue, parseRule, parseSelectors, parseStyleDeclaration, parseStyleSheet, parseStyleSheet, setConditionFactory, setDocumentHandler, setErrorHandler, setLocale, setSelectorFactory

Method from org.w3c.css.sac.Parser Detail:
public String getParserVersion() Returns a string about which CSS language is supported by this parser. For CSS Level 1, it returns "http://www.w3.org/TR/REC-CSS1", for CSS Level 2, it returns "http://www.w3.org/TR/REC-CSS2". Note that a "CSSx" parser can return lexical unit other than those allowed by CSS Level x but this usage is not recommended.
public boolean parsePriority(InputSource source) throws CSSException, IOException Parse a CSS priority value (e.g. "!important").
public LexicalUnit parsePropertyValue(InputSource source) throws CSSException, IOException Parse a CSS property value.
public void parseRule(InputSource source) throws CSSException, IOException Parse a CSS rule.
public SelectorList parseSelectors(InputSource source) throws CSSException, IOException Parse a comma separated list of selectors.
public void parseStyleDeclaration(InputSource source) throws CSSException, IOException Parse a CSS style declaration (without '{' and '}').
public void parseStyleSheet(InputSource source) throws CSSException, IOException Parse a CSS document. The application can use this method to instruct the CSS parser to begin parsing an CSS document from any valid input source (a character stream, a byte stream, or a URI). Applications may not invoke this method while a parse is in progress (they should create a new Parser instead for each additional CSS document). Once a parse is complete, an application may reuse the same Parser object, possibly with a different input source.
public void parseStyleSheet(String uri) throws CSSException, IOException Parse a CSS document from a URI. This method is a shortcut for the common case of reading a document from a URI. It is the exact equivalent of the following: parse(new InputSource(uri)); The URI must be fully resolved by the application before it is passed to the parser.
public void setConditionFactory(ConditionFactory conditionFactory)
public void setDocumentHandler(DocumentHandler handler) Allow an application to register a document event handler. If the application does not register a document handler, all document events reported by the CSS parser will be silently ignored (this is the default behaviour implemented by HandlerBase). Applications may register a new or different handler in the middle of a parse, and the CSS parser must begin using the new handler immediately.
public void setErrorHandler(ErrorHandler handler) Allow an application to register an error event handler. If the application does not register an error event handler, all error events reported by the CSS parser will be silently ignored, except for fatalError, which will throw a CSSException (this is the default behaviour implemented by HandlerBase). Applications may register a new or different handler in the middle of a parse, and the CSS parser must begin using the new handler immediately.
public void setLocale(Locale locale) throws CSSException Allow an application to request a locale for errors and warnings. CSS parsers are not required to provide localisation for errors and warnings; if they cannot support the requested locale, however, they must throw a CSS exception. Applications may not request a locale change in the middle of a parse.
public void setSelectorFactory(SelectorFactory selectorFactory)
