Method Detail

setLocale

public void setLocale(java.util.Locale locale)
               throws CSSException

Description copied from interface: Parser

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.

Specified by:

setLocale in interface Parser

Parameters:

locale - A Java Locale object.

Throws:

CSSException - Throws an exception (using the previous or default locale) if the requested locale is not supported.

See Also:

CSSException, CSSParseException

setDocumentHandler

public void setDocumentHandler(DocumentHandler handler)

Description copied from interface: Parser

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.

Specified by:

setDocumentHandler in interface Parser

Parameters:

handler - The document handler.

See Also:

DocumentHandler

setSelectorFactory

public void setSelectorFactory(SelectorFactory selectorFactory)

Specified by:

setSelectorFactory in interface Parser

setConditionFactory

public void setConditionFactory(ConditionFactory conditionFactory)

Specified by:

setConditionFactory in interface Parser

setErrorHandler

public void setErrorHandler(ErrorHandler handler)

Description copied from interface: Parser

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.

Specified by:

setErrorHandler in interface Parser

Parameters:

handler - The error handler.

See Also:

ErrorHandler, CSSException

parseStyleSheet

public void parseStyleSheet(InputSource source)
                     throws CSSException,
                            java.io.IOException

Description copied from interface: Parser

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.

Specified by:

parseStyleSheet in interface Parser

Parameters:

source - The input source for the top-level of the CSS document.

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

See Also:

InputSource, Parser.parseStyleSheet(java.lang.String), Parser.setDocumentHandler(org.w3c.css.sac.DocumentHandler), Parser.setErrorHandler(org.w3c.css.sac.ErrorHandler)

parseStyleSheet

public void parseStyleSheet(java.lang.String uri)
                     throws CSSException,
                            java.io.IOException

Description copied from interface: Parser

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.

Specified by:

parseStyleSheet in interface Parser

Parameters:

uri - The URI.

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

See Also:

Parser.parseStyleSheet(InputSource)

parseStyleDeclaration

public void parseStyleDeclaration(InputSource source)
                           throws CSSException,
                                  java.io.IOException

Description copied from interface: Parser

Parse a CSS style declaration (without '{' and '}').

Specified by:

parseStyleDeclaration in interface Parser

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

parseRule

public void parseRule(InputSource source)
               throws CSSException,
                      java.io.IOException

Description copied from interface: Parser

Parse a CSS rule.

Specified by:

parseRule in interface Parser

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

getParserVersion

public java.lang.String getParserVersion()

Description copied from interface: Parser

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.

Specified by:

getParserVersion in interface Parser

parseSelectors

public SelectorList parseSelectors(InputSource source)
                            throws CSSException,
                                   java.io.IOException

Description copied from interface: Parser

Parse a comma separated list of selectors.

Specified by:

parseSelectors in interface Parser

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

parsePropertyValue

public LexicalUnit parsePropertyValue(InputSource source)
                               throws CSSException,
                                      java.io.IOException

Description copied from interface: Parser

Parse a CSS property value.

Specified by:

parsePropertyValue in interface Parser

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

parsePriority

public boolean parsePriority(InputSource source)
                      throws CSSException,
                             java.io.IOException

Description copied from interface: Parser

Parse a CSS priority value (e.g. "!important").

Specified by:

parsePriority in interface Parser

Throws:

CSSException - Any CSS exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.
