    • insertRule

      public int insertRule(String ruleText, int index) throws DOMException
      Description copied from class: BaseCSSStyleSheet
      Used to insert a new rule into the style sheet. The new rule now becomes part of the cascade.
      Specified by:
      insertRule in interface CSSStyleSheet
      Overrides:
      insertRule in class BaseCSSStyleSheet
      Parameters:
      ruleText - The parsable text representing the rule. For rule sets this contains both the selector and the style declaration. For at-rules, this specifies both the at-identifier and the rule content.
      index - The index within the style sheet's rule list of the rule before which to insert the specified rule. If the specified index is equal to the length of the style sheet's rule collection, the rule will be added to the end of the style sheet.
      Returns:
      The index within the style sheet's rule collection of the newly inserted rule.
      Throws:
      DOMException - HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at the specified index e.g. if an @import rule is inserted after a standard rule set or other at-rule.
      INDEX_SIZE_ERR: Raised if the specified index is not a valid insertion point.
      NO_MODIFICATION_ALLOWED_ERR: Raised if this style sheet is readonly.
      SYNTAX_ERR: Raised if the specified rule has a syntax error and is unparsable.

    • parseStyleSheet

      public boolean parseStyleSheet(Reader reader, short commentMode) throws DOMException, IOException
      Description copied from class: BaseCSSStyleSheet
      Parses a style sheet.

      If the style sheet is not empty, the rules from the parsed source will be added at the end of the rule list, with the same origin as the rule with a highest precedence origin.

      If commentMode is not COMMENTS_IGNORE, the comments preceding a rule shall be available through CSSRule.getPrecedingComments(), and if COMMENTS_AUTO was set also the trailing ones, through the method CSSRule.getTrailingComments().

      This method resets the state of this sheet's error handler.

      To create a sheet, see CSSStyleSheetFactory.createStyleSheet(String,MediaQueryList)

      Specified by:
      parseStyleSheet in interface CSSStyleSheet<AbstractCSSRule>
      Overrides:
      parseStyleSheet in class BaseCSSStyleSheet
      Parameters:
      reader - the character stream containing the CSS sheet.
      commentMode - 0 if comments have to be ignored, 1 if all comments are considered as preceding a rule, 2 if the parser should try to figure out which comments are preceding and trailing a rule (auto mode).
      Returns:
      true if the SAC parser reported no errors or fatal errors, false otherwise.
      Throws:
      DOMException - if raised by the error handler.
      IOException - if a problem is found reading the sheet.
